== Upgrading from previous releases ==
As usual, the supported methods for upgrading from previous Fedora releases are to do an 'upgrade install' from the regular installation media, or to use preupgrade (see [[How_to_use_PreUpgrade]]). Upgrading by using yum directly is not supported, but may in practice work. For known issues when upgrading via yum, see [[Upgrading_Fedora_using_yum#10-11|the page on this upgrade method]].

{{Anchor|libfprint-nonzero}}
=== Some fingerprint readers do not work with ''non-zero bytes in cmd response'' error ===
<small>[[Common F11 bugs#libfprint-nonzero|link to this item]] - [[rhbug:500460|Bugzilla: #500460]]</small>
Some fingerprint reader models (including at least the ones in some Thinkpad T43 laptop models) failed to work at all in Fedora 11. If you ran an application which attempts to use the fingerprint reader from a console, the following error messages were observed:
<pre>
upekts:warning [__handle_incoming_msg] non-zero bytes in cmd response: fb ff
</pre>
An updated [http://admin.fedoraproject.org/updates/libfprint-0.1.0-7.pre2.fc11.1 libfprint] package has been released to address this issue. Update your system as usual to receive this update, if you do not yet already have it.
{{Anchor|491754}}
=== Installation fails with ''DeviceError: cannot commit to disk sda after 5 attempts'' ===
<small>[[Common F11 bugs#491754|link to this item]] - [[rhbug:491754|Bugzilla: #491754]]</small>
Several users reported a failure during installation of {{FedoraVersion|long|11}}. While partitioning your disk(s), the anaconda installer might fail and present an error message indicating ''DeviceError: cannot commit to disk sda after 5 attempts''. Subsequent attempts to install the system using the same steps appear to be successful in some, but not all, cases. In other cases, changing the chosen partition layout seemed to avoid the problem.
An [http://dcantrel.fedorapeople.org/491754.img updates.img] file is available to work around the defect. This image is provided through the Fedora project space of David Cantrell, one of the Anaconda maintainers. For additional information on using an {{filename|updates.img}} with the installer, see [[Anaconda/Updates]].

=== QEMU/KVM DVD installs under a {{FedoraVersion|long|11}} host hang when attempting to eject DVD ===
<small>[[Common F11 bugs#501412|link to this item]] - [[rhbug:501412|Bugzilla: #501412]]</small>
 
KVM users may experience that Fedora 11 DVD installs hang prior to ejecting the virtual optical DVD mediaThis issue is the result of interactions in QEMU's IDE CDROM emulation for
eject and tray locking.  Users may work around this issue by restarting the hung guest.

{{Anchor|emu10k1-digital-fail}}
=== Sound Blaster Live! cards (and other emu10k1-based cards) do not work ===
<small>[[Common F11 bugs#emu10k1-digital-fail|link to this item]] - [[rhbug:502698|Bugzilla: #502698]]</small>
 
Multiple users reported that emu10k1-based sound cards does not work in Fedora 11. This includes many Sound Blaster Live! sound cards, and several others. When trying to play a sound file, no sound was heard, and the system recorded several failure messages from the kernel, similar to this:
<pre>
ALSA sound/core/pcm_lib.c:166: BUG: stream = 0, pos = 0x2000, buffer size = 0x2000, period size = 0x2000
</pre>
This issue was fixed with the upgrade to the 2.6.30 kernel series. Any 2.6.30-versioned Fedora 11 kernel should be free from this issue. Update your system as usual to receive this update, if you do not yet already have it.
 
{{Anchor|random-display-blank}}
=== Display goes blank briefly, apparently at random ===
<small>[[Common F11 bugs#random-display-blank|link to this item]] - [[rhbug:501601|Bugzilla: #501601]]</small>
 
Several users have reported that their display will sometimes suddenly go blank for a brief period - a second or two - before coming back. This is caused by problems in how X handles idle time counting.
 
Most users report that this issue is fixed with updated [http://admin.fedoraproject.org/updates/xorg-x11-server-1.6.3-4.fc11 xorg-x11-server] and [http://admin.fedoraproject.org/updates/gnome-power-manager-2.26.4-3.fc11 gnome-power-manager] packages. Update your system as usual to receive these updates, if you do not yet already have them.
 
== Issues when upgrading from previous releases ==
 
As usual, the supported methods for upgrading from previous Fedora releases are to do an 'upgrade install' from the regular installation media, or to use preupgrade (see [[How_to_use_PreUpgrade]]). Upgrading by using yum directly is not supported, but may in practice work. For known issues when upgrading via yum, see [[Upgrading_Fedora_using_yum#10-11|the page on this upgrade method]].
 
{{Anchor|501057}}
 
=== Upgrade fails while editing existing bootloader entry ===
<small>[[Common F11 bugs#501057|link to this item]] - [[rhbug:501057|Bugzilla: #501057]]</small>
 
While upgrading your system using anaconda, the Fedora installer, you are given the option to update your bootloader configuration, create a new bootloader configuration or skip any bootloader configuration changes.  When choosing to create a new bootloader configuration, the installer may fail while attempting to edit the default bootloader target created by the installer.  To work around this issue, edit the default bootloader configuration after the upgrade completes and your system reboots.  If changes are needed prior to a system reboot, you may manually edit the configuration by pressing <code><ctrl><alt>F2</code> and edit the bootloader configuration file by typing: <pre> vi /mnt/sysimage/etc/grub.conf</pre>
 
===Can't find .i686 kernel===
 
The kernel.i686 RPM is no longer produced.  All .i386 and .i486 packages have been rebuilt as .i586 (Pentium class). These designations represent the ''minimum'' supported architecture version; Fedora 11 is ''optimized'' for Pentium 4-compatible and later processors.  Fedora has never officially supported pre-Pentium architectures, and dropping any remaining backwards compatibility with these chips further improves performance and allows for code simplification.
 
The following kernels are available instead:


A test build that should resolve this problem is available from Koji: [http://koji.fedoraproject.org/koji/taskinfo?taskID=1379557 gnome-packagekit-2.27.2-0.1056.20090527git.fc11]. If you are affected by this issue, please test this update and report your results to the [[rhbug:492005|bug report]].
* kernel.i586, for those requiring compatibility with a Pentium-class architecture or who do not have a PAE and NX capable processor.
* kernel-PAE.i686, which requires a PAE and NX capable processor with Pentium PRO-class or later architecture.


In the meantime, changing the following option in the configuration file <tt>/etc/PackageKit/PackageKit.conf</tt> may work for some people, although results vary:
After analyzing the differences between the i585 and i686 architectures, dropping the non-PAE i686 kernel is not expected to have a negative performance impact for those required to use the kernel.i586 package. The kernel-PAE.i686 RPM has additional capabilities, such as support for ExecShield security and the ability to address up to 64GB of RAM (the standard kernel can address only 4GB).  Note that the architecture designations in RPM names represent the ''minimum'' supported architecture version; Fedora 11 is ''optimized'' for Pentium 4-compatible and later processors.

Anaconda (the recommended install method) will automatically choose the best kernel for your hardware.
=== Screen stays black when returning from idle mode on Thinkpad X41T ===
<small>[[Common F11 bugs#x41t-dpms-die|link to this item]] - [[rhbug:489907|Bugzilla: #489907]]</small>


On the Lenovo / IBM Thinkpad X41T model laptop, with default settings, the screen will fail to turn back on once it has gone into power-saving idle mode (either on a timeout, or on closing and re-opening the lid). Disabling kernel modesetting via the <tt>nomodeset</tt> kernel parameter works around this problem, but may cause other problems to occur instead. Another workaround is to create a file with the following contents:
If you are using the "yum upgrade" method (not recommended), you may receive the kernel.i586 package even if your processor would support the kernel-PAE.i686 package. To determine this, run the command:
<pre>
<pre>
#!/bin/bash
grep 'flags.* pae' /proc/cpuinfo | grep -wq nx && echo 'kernel-PAE'
xrandr --output LVDS1 --off
xrandr --output LVDS1 --auto
</pre>
</pre>
Make it executable, and set a shortcut key combination to launch it. Running the script via the shortcut should restore the display. Fedora developers are currently working on a fix for this problem.
If you see "kernel-PAE" in the output, then your CPU is capable of using this package, and you can manually "yum install kernel-PAE".
 
{{Anchor|501063}}
 
=== The installer does not honor ''skip bootloader'' choice ===
<small>[[Common F11 bugs#501063|link to this item]] - [[rhbug:501063|Bugzilla: #501063]]</small>
 
While upgrading your system using anaconda, the Fedora installer, you are given the option to update your bootloader configuration, create a new bootloader configuration or skip any bootloader configuration changes.  When choosing to '''skip'' any bootloader configuration changes, the installer will ignore this select and update any existing bootloader configuration. To work around this issue, save the existing bootloader configuration prior to upgrade, and restore that configuration after the upgrade completes and your system reboots. If changes are needed prior to a system reboot, you may manually edit the configuration by pressing <code><ctrl><alt>F2</code> and edit the bootloader configuration file by typing: <pre> vi /mnt/sysimage/etc/grub.conf</pre>
 
{{Anchor|506685}}
 
=== Yum doesn't work after upgrading from F10 ===
<small>[[Common F11 bugs#506685|link to this item]] - [[rhbug:506685|Bugzilla: #506685]]</small>


{{Anchor|nouveau-agp}}
When upgrading from an updated F10 install, yum ends up not working - outputting an error about no yum module found.
=== Graphical desktop failing to start or crashing with AGP NVIDIA graphics cards ===
<small>[[Common F11 bugs#nouveau-agp|link to this item]] - [[rhbug:490358|Bugzilla: #490358]], [[rhbug:487456|Bugzilla: #487456]], [[rhbug:498579|Bugzilla: #498579]], [[rhbug:499730|Bugzilla: #499730]]</small>


Problems have been reported with several NVIDIA AGP graphics cards, with the new ''nouveau'' graphics driver used in Fedora 11. AGP is a tricky case that the driver does not yet handle well for several cards. If you experience failure to start the graphical desktop (X server), or hanging or crashing of the graphical desktop, and you have an NVIDIA-based AGP graphics card, you may want to try the following workaround. Add the kernel parameter <tt>nouveau.noagp=1</tt>. For many reporters, this resolves the problem.
The version of yum in f10-updates was newer than the one in F11-GA  - it caused yum to not be updated during the anaconda upgrade process. There is a simple one-time work around as root:


Some NVIDIA onboard graphics chipsets use AGP, as well as expansion cards that fit in an AGP slot. To check whether your onboard chipset is an AGP one, run this command:
<pre>
<pre>
grep -i agp /var/log/Xorg.0.log
export PYTHONPATH=/usr/lib/python2.5/site-packages
 
yum clean all
 
yum update yum
 
</pre>
</pre>
if it returns anything, your chip is an AGP one. If not, it isn't.


If you experience a problem of this kind, and your graphics card is not the same model as in any of the existing reports listed above, please file a new bug report on the ''xorg-x11-drv-nouveau'' component, explaining your symptoms, and providing [[BugsAndFeatureRequests#Xorg|all the usual information required for X.org bug reports]].
That should update you to the current yum from F11-updates and you'll be all set.
 
== Installation issues ==
 
{{Anchor|Hash-update}}
{{Anchor|504228}}
=== Documentation for ISO images is faulty ===
<small>[[Common F11 bugs#Hash-update|link to this item]] - [[rhbug:504228|Bugzilla: #504228]]</small>
 
The {{filename|README-BURNING-ISOS}} file distributed on mirrors along with the CD and DVD images contains an incorrect filename for the checksum file, which is now {{filename|Fedora-11-<arch>-CHECKSUM}}.  Additionally, it refers to SHA-1 checksums instead of SHA-256 checksums.  To check the contents of a downloaded ISO image using an existing Linux operating system, use the {{command|sha256sum}} command instead of {{command|sha1sum}}.  As stated correctly in the document, the BitTorrent download method automatically performs checksums during download, so no additional procedure is required in that case.
 
The Documentation team [[rhbug:504228 | is aware of this bug]].  Although the file cannot be easily changed after mirror distribution, this issue will be fixed for the next release.
 
{{Anchor|498553}}
=== Live image installations fail with ''FSError: filesystem has not been created'' ===
<small>[[Common F11 bugs#498553|link to this item]] - [[rhbug:498553|Bugzilla: #498553]]</small>
 
Several users have reported a failure occurring during installation from a {{FedoraVersion|long|11}} live media environment.  During the disk partitioning phase of the installer, a window focus interaction issue between the ''metacity'', the GNOME window manager, and the Fedora installer may allow the user to click the <code>Next</code> button of the installer before partitioning has completed.  Doing so will result in a failure message, ''FSError: filesystem has not been created''.  To workaround this issue, it is recommended that users verify that no installer partitioning progress dialogs are present before clicking the ''Next'' button until all partitioning operations have completed.  Due to the windowing environment that the live image installer runs from, it is possible that a partitioning progress dialog does not have focus and is behind the main installer window.  Before proceeding to the ''Next'' phase of the installation, verify that no installer partitioning progress dialogs are present.
 
{{Anchor|494000}}
=== Booting {{FedoraVersion|long|11}} live media created with liveusb-creator from a {{FedoraVersion|long|9}} or {{FedoraVersion|long|10}} system fails to boot ===
<small>[[Common F11 bugs#494000|link to this item]] - [[rhbug:494000|Bugzilla: #494000]]</small>
 
{{FedoraVersion|long|11}} live media created from a {{FedoraVersion|long|9}} system using liveusb-creator may fail during boot with a message, ''Unable to find root filesystem'' or a grey screen. The recommended workaround for this issue is to use livecd-iso-to-disk - the command line tool - instead, with reference to [[Common_F11_bugs#498155|issue 498155 above]] for {{FedoraVersion|long|9}} users, and to the [[How_to_create_and_use_Live_USB#Command_Line_Method_-_Linux_only|instructions for using this tool]]. {{FedoraVersion|long|10}} may be able to work around the issue by installing the Fedora 11 version of the ''syslinux'' package, but that may have unpredictable results for other operations and is hence not recommended.
 
{{Anchor|499544}}
 
=== Installation fails with ''PartitionException: Can't have overlapping partitions'' ===
<small>[[Common F11 bugs#499544|link to this item]] - [[rhbug:499544|Bugzilla: #499544]]</small>
 
Several users have reported installation failures while attempting to re-use or resize existing disk partitions during an install.  The most common reproducer occurs while resizing existing partitions under the ''Create custom layout'' partitioning option.  If you encounter this failure and the use of existing partitions is required, it is recommended that you resize your partitions prior to performing the installation.  This page will be updated when more information is available.
 
{{Anchor|502310}}
=== Installation fails while editing previously encrypted partition - ''IndexError: list index out of range'' ===
<small>[[Common F11 bugs#502310|link to this item]] - [[rhbug:502310|Bugzilla: #502310]]</small>
 
Several users have reported installation failures while attempting to edit previously encrypted disk partitions during an install.  When the installer discovers encrypted volumes, it will prompt the user for a passphrase needed to unlock the encrypted partitions.  If the user does not enter a passphrase, and later attempts to edit a previously encrypted partition under the ''Create custom layout'' partitioning option, the installer will fail with a message, ''IndexError: list index out of range''.  To work around this issue, users are advised to enter a passphrase when prompted for any previously encrypted disk partitions.  If the passphrase is not known, you are advised to let the installer partition your disks using the ''Use entire drive'' option, or edit any previously encrypted disk partitions by hand prior to installation.
 
{{Anchor|503310}}
=== Kickstart installations cannot reuse existing RAID arrays ===
<small>[[Common F11 bugs#503310|link to this item]] - [[rhbug:503310|Bugzilla: #503310]]</small>
 
Kickstart installations which attempt to reuse existing RAID arrays (raid --useexisting) will fail with an error that the array name is not recognized.  Anaconda does recognize (and can use) the RAID autostart partitions, but cannot reuse their assembly in any existing arrays.  Semi-automatic kickstart installations with manual layout also exhibit the issue.
 
An installer patch {{filename|updates.img}} image is (presently) available which should fix this problem. You can find it [http://rvykydal.fedorapeople.org/updates.clearpart.img here]. That is the personal space of one of the Anaconda developers. For additional information on using an {{filename|updates.img}} with the installer, see [[Anaconda/Updates]].
 
If you cannot use the installer patch, to work around the issue, you must either rebuild the array, losing all existing data in the array, or perform the installation without kickstart.  Fully manual installations do not exhibit the issue.  The inability to reuse existing arrays is limited to kickstart installations only.
 
{{Anchor|503681}}
 
=== Kickstart installations cannot reuse existing LVM volume groups ===
<small>[[Common F11 bugs#503681|link to this item]] - [[rhbug:503681|Bugzilla: #503681]]</small>
 
Kickstart installations which attempt to reuse existing LVM volume groups (volgroup --useexisting) will fail with an error that the volume group name is not recognized.  Anaconda does recognize (and can use) LVM physical volume partitions, but cannot reuse their membership in any existing volume groups.  Semi-automatic kickstart installations with manual layout also exhibit the issue.
 
An installer patch {{filename|updates.img}} image is (presently) available which should fix this problem. You can find it [http://rvykydal.fedorapeople.org/updates.clearpart.img here]. That is the personal space of one of the Anaconda developers. For additional information on using an {{filename|updates.img}} with the installer, see [[Anaconda/Updates]].
 
If you cannot use the installer patch, to work around the issue, you must either recreate the group, losing all its existing logical volumes and the data they contain, or perform the installation without kickstart.  Fully manual installations do not exhibit the issue.  The inability to reuse existing volume groups is limited to kickstart installations only.
 
{{Anchor|504687}}
=== Kickstart installations fail when using partition options --ondisk or --biosdisk ===
<small>[[Common F11 bugs#504687|link to this item]] - [[rhbug:504687|Bugzilla: #504687]]</small>
 
Kickstart installations which use either the <code>--ondisk</code> or <code>--biosdisk</code> options to the <code>part</code> kickstart command will not work.  A workaround for Fedora 11 is to avoid using either kickstart options.  If use of the options <code>--ondisk</code> or <code>--biosdisk</code> is required, an [http://clumens.fedorapeople.org/504687.img updates.img] is available to work around the defect.  For additional information on using an updates.img with the installer, see [[Anaconda/Updates]].
 
{{Anchor|ppc970-no-hd}}
=== Installer sees no hard drives on ppc970 systems ===
<small>[[Common F11 bugs#ppc970-no-hd|link to this item]] - [[rhbug:504040|Bugzilla: #504040]]</small>
 
There is a problem with yaboot on ppc970-based systems which causes the installer to be unable to find the system's hard drives. This prevents installation or upgrade from working.
 
There is a fix for yaboot, but the fixed package is not present on the Fedora 11 media. However, an [http://jwboyer.fedorapeople.org/boot.iso updated installer image] with this bug fixed is available. The image was built by Fedora contributor and Red Hat employee Josh Boyer and is hosted on his space on the Fedora People server. You can use the image as you would any other {{filename|boot.iso}} image, to install from a network source or from a Fedora 11 image or disc. See the [http://docs.fedoraproject.org/install-guide/f11/ installation guide] for more details.

<small>[[Common F11 bugs#496760|link to this item]] - [[rhbug:496760|Bugzilla: #496760]]</small>
 
There is a problem while creating logical volumes during installation.  The steps to reproduce this failure were originally verified prior to release of Fedora 11.  Since the release, it appears there may be new failure vectors for this same issue.  If you are experiencing this failure, you will need to reboot your system and retry the installation.  Root cause for this issue is being investigated.

=== Writing installation failure tracebacks to a USB key does not work ===
<small>[[Common F11 bugs#usb-traceback-anaconda|link to this item]] - [[rhbug:491700|Bugzilla: #491700]]</small>
 
In some circumstances, when installation fails and the installer (Anaconda) offers to write the traceback to a USB key for debugging purposes, this does not work properly. Even after inserting a key, it may not be shown in the list Anaconda presents. If you experience this problem, try removing and re-inserting the USB key; this may circumvent the problem.
 
This bug was fixed after the release of Fedora 11. As it is an installer bug, an update to fix it cannot be provided.

=== Installer ignores incomplete BIOS RAID array disks, nodmraid kernel parameter not honored ===
<small>[[Common F11 bugs#dmraid-nodmraid|link to this item]] - [[rhbug:499733|Bugzilla: #499733]]</small>
 
In Fedora 11, a deliberate change was made to the installer (Anaconda) in the case where a BIOS RAID array is present but the metadata for the array is incomplete. In past releases, the individual disks from the array would be available in the installer. In Fedora 11, they are ignored. This change is intentional. However, a kernel parameter - ''nodmraid'' - which should override this behaviour in the case where you wish to install to the disks is supposed to be available, but does not work. This is a bug.
 
Another way to address the problem - actually preferred to using ''nodmraid'' - is to remove the incomplete metadata by running the command {{command|dmraid -rE}} on the array in question. Please backup your data before attempting to do this. Please see the bug report for further discussion of this issue.

=== Resume from suspend fails with NVIDIA graphics adapters ===
<small>[[Common F11 bugs#nouveau-suspend|link to this item]] - [[rhbug:459323|Bugzilla: #459323]]</small>
 
Resuming from suspend fails to restore the graphical display when using the nouveau video driver, which is now the default for all NVIDIA video adapters in Fedora 11. Unfortunately, there is no workaround for this problem, and it is not likely to be fixed within the Fedora 11 timeframe. If you have a system with an NVIDIA video adapter on which you need suspend/resume functionality, you must use an alternative driver. The old ''nv'' free driver will work for some cards, but for others, only the proprietary ''nvidia'' driver will work. To switch to the ''nv'' driver, you can use the ''system-config-display'' utility - on the ''Hardware'' tab, click the ''Configure...'' button next to '''Video Card''' and select the ''nv'' driver from the list.

Several users with many different Intel graphics adapters have reported text displayed in applications becomes heavily corrupted after the system has been running for a while. Disabling kernel modesetting, using the <tt>nomodeset</tt> parameter, works around this issue. The cause of this problem is under investigation and we hope to provide an official update to resolve it shortly after the release of Fedora 11.
Problems have been reported with several NVIDIA AGP graphics cards, with the new ''nouveau'' graphics driver used in Fedora 11. AGP is a tricky case that the driver does not yet handle well for several cards. If you experience failure to start the graphical desktop (X server), or hanging or crashing of the graphical desktop, and you have an NVIDIA-based AGP graphics card, you may want to try the following workaround. Add the kernel parameter <code>nouveau.noagp=1</code>. For many reporters, this resolves the problem.
 
Some NVIDIA onboard graphics chipsets use AGP, as well as expansion cards that fit in an AGP slot. To check whether your onboard chipset is an AGP one, run this command:
<pre>
grep -i agp /var/log/Xorg.0.log
</pre>
if it returns anything, your chip is an AGP one. If not, it isn't.

Fedora 11 introduces a simplified, PulseAudio-based GNOME volume control applet and application: see the release notes for more details on this. This, and other PA-based volume controls like pavucontrol, rely on PulseAudio to set the volume level. In some cases where the underlying ALSA volumes do not default to sensible values, PulseAudio-based volume control applications cannot properly adjust the volume: for instance, you hear no sound even with the control set to max, or setting the control to its lowest level still results in audible sound.

Fedora 11 introduces a simplified, PulseAudio-based GNOME volume control applet and Sound Preferences application: see the [http://docs.fedoraproject.org/release-notes/f11/ release notes], section 4.5 Multimedia, for more details on this.  
 
This, and other PA-based volume controls like pavucontrol, rely on PulseAudio to set the volume level. In some cases where the underlying ALSA volumes do not default to sensible values, PulseAudio-based volume control applications cannot properly adjust the volume: for instance, you hear no sound even with the control set to max, or setting the control to its lowest level still results in audible sound.  
 
In these cases, you can use the legacy volume control application installed by default in Fedora 11 to control the underlying ALSA volumes directly. It can be found in the menus under System / Preferences, with the name Advanced Volume Control. If you upgrade from Fedora 10 to Fedora 11, this volume control application may not be installed: install the package {{package|gst-mixer}} to gain access to it.
 
If you find yourself in this situation, please [https://bugzilla.redhat.com/enter_bug.cgi?product=Fedora&component=pulseaudio&version=11 file a new bug report] on the ''pulseaudio'' component, according to [https://bugzilla.redhat.com/show_bug.cgi?id=497966#c1 these instructions], and set it to block the bug AlsaVolume.

Some users have reported that when attempting to use the "nvidia" kernel module (either the official installer or kmod-nvidia*) Xorg will fail to start properly. The end result, Fedora 11 boots to a black screen. Inspection of dmesg may reveal many messages similar to:

vmap allocation for size 4198400 failed: use vmalloc=<size> to increase size.
</pre>
A workaround is to add an entry to your kernel line in /etc/grub.conf that includes the amount of video memory on your nVidia card, for example for a 128 MB Geforce 8400 GS you would append the following:
<pre>
vmalloc=128MB

After installation, it might be noticed that programs requiring the network can not connect to the network. If this is the case, the ''NetworkManager'' icon may show a red X indicating that the machine is not currently connected. While all networking hardware is correctly wired, and device indicators show the network to be properly connected, a change in default install behaviour means that the network does not immediately connect.
 
The required procedure from this point is to click the ''NetworkManager'' icon, and activate the System eth0 or similar connection. If the red X disappears from the ''NetworkManager'' icon, then this was the issue that was stopping the connection from being activated.
 
However, the above change is only for the current login. To make this change permanent, right click the ''NetworkManager'' icon, Edit connections, select the System eth0 or similar, click Edit, provide the root password, check the Connect automatically item at the top of the dialog box, Apply and Close.

=== Resume from suspend fails, kernel oops notification appears on reboot ===
<small>[[Common F11 bugs#suspend-oops|link to this item]] - [[rhbug:499651|Bugzilla: #499651]]</small>
 
Several users have reported a failure to resume from suspend on various systems. On some systems this happens every time, on others it is quasi-random. When attempting to resume from suspend, the system hangs at a black screen. On rebooting, you are asked to report a kernel oops - ending with ''[<c040945f>] sysenter_do_call+0x12/0x34'' - to the kernel bug tracking system (unless you have this feature disabled).
 
A workaround for this issue is discussed in the bug report. Create a file {{filename|/etc/pm/sleep.d/00-cpuspeed.sh}} with the following contents:
<pre>
#!/bin/bash
if [ "$1" == "suspend" ]; then
  service cpuspeed stop
  modprobe -r acpi_cpufreq

If you have a floppy drive controller in your system that is enabled in the BIOS, but no actual floppy drive, you may be affected by an issue where the boot process pauses for a significant time (at least a minute). If you hit the Escape key to see verbose boot messages, you will see that it hangs at the 'Starting udev' stage. There are two known workarounds for this issue.

Resolved issues

Some fingerprint readers do not work with non-zero bytes in cmd response error

link to this item - Bugzilla: #500460

Some fingerprint reader models (including at least the ones in some Thinkpad T43 laptop models) failed to work at all in Fedora 11. If you ran an application which attempts to use the fingerprint reader from a console, the following error messages were observed:

upekts:warning [__handle_incoming_msg] non-zero bytes in cmd response: fb ff

An updated libfprint package has been released to address this issue. Update your system as usual to receive this update, if you do not yet already have it.

Installation fails with DeviceError: cannot commit to disk sda after 5 attempts

link to this item - Bugzilla: #491754

Several users reported a failure during installation of Fedora 11. While partitioning your disk(s), the anaconda installer might fail and present an error message indicating DeviceError: cannot commit to disk sda after 5 attempts. Subsequent attempts to install the system using the same steps appear to be successful in some, but not all, cases. In other cases, changing the chosen partition layout seemed to avoid the problem.

An updates.img file is available to work around the defect. This image is provided through the Fedora project space of David Cantrell, one of the Anaconda maintainers. For additional information on using an updates.img with the installer, see Anaconda/Updates.

Update notification doesn't disappear

link to this item - Bugzilla: #492005

After updating using PackageKit, the updates notice may reappear even when there are no package updates left to receive.

An updated gnome-packagekit package has been released to address this issue. Update your system as usual to receive this update, if you do not yet already have it.

Booting Fedora 11 live media created with livecd-iso-to-disk from a Fedora 9 system fails to boot

link to this item - Bugzilla: #498155

Fedora 11 live media created from a Fedora 9 system using livecd-iso-to-disk may fail during boot with a message, Unable to find root filesystem or a grey screen.

An updated livecd-tools package has been released to address this issue. Update your system as usual to receive this update, if you do not yet already have it.

QEMU/KVM DVD installs under a Fedora 11 host hang when attempting to eject DVD

link to this item - Bugzilla: #501412

KVM users may experience that Fedora 11 DVD installs hang prior to ejecting the virtual optical DVD media. This issue is the result of interactions in QEMU's IDE CDROM emulation for eject and tray locking. Users may work around this issue by restarting the hung guest.

An updated qemu package has been released to address this issue. Update your system as usual to receive this update, if you do not yet already have it.

Sound Blaster Live! cards (and other emu10k1-based cards) do not work

link to this item - Bugzilla: #502698

Multiple users reported that emu10k1-based sound cards does not work in Fedora 11. This includes many Sound Blaster Live! sound cards, and several others. When trying to play a sound file, no sound was heard, and the system recorded several failure messages from the kernel, similar to this:

ALSA sound/core/pcm_lib.c:166: BUG: stream = 0, pos = 0x2000, buffer size = 0x2000, period size = 0x2000

This issue was fixed with the upgrade to the 2.6.30 kernel series. Any 2.6.30-versioned Fedora 11 kernel should be free from this issue. Update your system as usual to receive this update, if you do not yet already have it.

Display goes blank briefly, apparently at random

link to this item - Bugzilla: #501601

Several users have reported that their display will sometimes suddenly go blank for a brief period - a second or two - before coming back. This is caused by problems in how X handles idle time counting.

Most users report that this issue is fixed with updated xorg-x11-server and gnome-power-manager packages. Update your system as usual to receive these updates, if you do not yet already have them.

Issues when upgrading from previous releases

As usual, the supported methods for upgrading from previous Fedora releases are to do an 'upgrade install' from the regular installation media, or to use preupgrade (see How_to_use_PreUpgrade). Upgrading by using yum directly is not supported, but may in practice work. For known issues when upgrading via yum, see the page on this upgrade method.

Upgrade fails while editing existing bootloader entry

link to this item - Bugzilla: #501057

While upgrading your system using anaconda, the Fedora installer, you are given the option to update your bootloader configuration, create a new bootloader configuration or skip any bootloader configuration changes. When choosing to create a new bootloader configuration, the installer may fail while attempting to edit the default bootloader target created by the installer. To work around this issue, edit the default bootloader configuration after the upgrade completes and your system reboots. If changes are needed prior to a system reboot, you may manually edit the configuration by pressing <ctrl><alt>F2 and edit the bootloader configuration file by typing:

 vi /mnt/sysimage/etc/grub.conf

Can't find .i686 kernel

The kernel.i686 RPM is no longer produced. All .i386 and .i486 packages have been rebuilt as .i586 (Pentium class). These designations represent the minimum supported architecture version; Fedora 11 is optimized for Pentium 4-compatible and later processors. Fedora has never officially supported pre-Pentium architectures, and dropping any remaining backwards compatibility with these chips further improves performance and allows for code simplification.

The following kernels are available instead:

  • kernel.i586, for those requiring compatibility with a Pentium-class architecture or who do not have a PAE and NX capable processor.
  • kernel-PAE.i686, which requires a PAE and NX capable processor with Pentium PRO-class or later architecture.

After analyzing the differences between the i585 and i686 architectures, dropping the non-PAE i686 kernel is not expected to have a negative performance impact for those required to use the kernel.i586 package. The kernel-PAE.i686 RPM has additional capabilities, such as support for ExecShield security and the ability to address up to 64GB of RAM (the standard kernel can address only 4GB). Note that the architecture designations in RPM names represent the minimum supported architecture version; Fedora 11 is optimized for Pentium 4-compatible and later processors.

Anaconda (the recommended install method) will automatically choose the best kernel for your hardware.

If you are using the "yum upgrade" method (not recommended), you may receive the kernel.i586 package even if your processor would support the kernel-PAE.i686 package. To determine this, run the command:

grep 'flags.* pae' /proc/cpuinfo | grep -wq nx && echo 'kernel-PAE'

If you see "kernel-PAE" in the output, then your CPU is capable of using this package, and you can manually "yum install kernel-PAE".

The installer does not honor skip bootloader choice

link to this item - Bugzilla: #501063

While upgrading your system using anaconda, the Fedora installer, you are given the option to update your bootloader configuration, create a new bootloader configuration or skip any bootloader configuration changes. When choosing to 'skip any bootloader configuration changes, the installer will ignore this select and update any existing bootloader configuration. To work around this issue, save the existing bootloader configuration prior to upgrade, and restore that configuration after the upgrade completes and your system reboots. If changes are needed prior to a system reboot, you may manually edit the configuration by pressing <ctrl><alt>F2 and edit the bootloader configuration file by typing:

 vi /mnt/sysimage/etc/grub.conf

Yum doesn't work after upgrading from F10

link to this item - Bugzilla: #506685

When upgrading from an updated F10 install, yum ends up not working - outputting an error about no yum module found.

The version of yum in f10-updates was newer than the one in F11-GA - it caused yum to not be updated during the anaconda upgrade process. There is a simple one-time work around as root:

export PYTHONPATH=/usr/lib/python2.5/site-packages

yum clean all

yum update yum

That should update you to the current yum from F11-updates and you'll be all set.

Installation issues

Documentation for ISO images is faulty

link to this item - Bugzilla: #504228

The README-BURNING-ISOS file distributed on mirrors along with the CD and DVD images contains an incorrect filename for the checksum file, which is now Fedora-11-<arch>-CHECKSUM. Additionally, it refers to SHA-1 checksums instead of SHA-256 checksums. To check the contents of a downloaded ISO image using an existing Linux operating system, use the sha256sum command instead of sha1sum. As stated correctly in the document, the BitTorrent download method automatically performs checksums during download, so no additional procedure is required in that case.

The Documentation team is aware of this bug. Although the file cannot be easily changed after mirror distribution, this issue will be fixed for the next release.

Live image installations fail with FSError: filesystem has not been created

link to this item - Bugzilla: #498553

Several users have reported a failure occurring during installation from a Fedora 11 live media environment. During the disk partitioning phase of the installer, a window focus interaction issue between the metacity, the GNOME window manager, and the Fedora installer may allow the user to click the Next button of the installer before partitioning has completed. Doing so will result in a failure message, FSError: filesystem has not been created. To workaround this issue, it is recommended that users verify that no installer partitioning progress dialogs are present before clicking the Next button until all partitioning operations have completed. Due to the windowing environment that the live image installer runs from, it is possible that a partitioning progress dialog does not have focus and is behind the main installer window. Before proceeding to the Next phase of the installation, verify that no installer partitioning progress dialogs are present.

Booting Fedora 11 live media created with liveusb-creator from a Fedora 9 or Fedora 10 system fails to boot

link to this item - Bugzilla: #494000

Fedora 11 live media created from a Fedora 9 system using liveusb-creator may fail during boot with a message, Unable to find root filesystem or a grey screen. The recommended workaround for this issue is to use livecd-iso-to-disk - the command line tool - instead, with reference to issue 498155 above for Fedora 9 users, and to the instructions for using this tool. Fedora 10 may be able to work around the issue by installing the Fedora 11 version of the syslinux package, but that may have unpredictable results for other operations and is hence not recommended.

Installation fails with PartitionException: Can't have overlapping partitions

link to this item - Bugzilla: #499544

Several users have reported installation failures while attempting to re-use or resize existing disk partitions during an install. The most common reproducer occurs while resizing existing partitions under the Create custom layout partitioning option. If you encounter this failure and the use of existing partitions is required, it is recommended that you resize your partitions prior to performing the installation. This page will be updated when more information is available.

Installation fails while editing previously encrypted partition - IndexError: list index out of range

link to this item - Bugzilla: #502310

Several users have reported installation failures while attempting to edit previously encrypted disk partitions during an install. When the installer discovers encrypted volumes, it will prompt the user for a passphrase needed to unlock the encrypted partitions. If the user does not enter a passphrase, and later attempts to edit a previously encrypted partition under the Create custom layout partitioning option, the installer will fail with a message, IndexError: list index out of range. To work around this issue, users are advised to enter a passphrase when prompted for any previously encrypted disk partitions. If the passphrase is not known, you are advised to let the installer partition your disks using the Use entire drive option, or edit any previously encrypted disk partitions by hand prior to installation.

Kickstart installations cannot reuse existing RAID arrays

link to this item - Bugzilla: #503310

Kickstart installations which attempt to reuse existing RAID arrays (raid --useexisting) will fail with an error that the array name is not recognized. Anaconda does recognize (and can use) the RAID autostart partitions, but cannot reuse their assembly in any existing arrays. Semi-automatic kickstart installations with manual layout also exhibit the issue.

An installer patch updates.img image is (presently) available which should fix this problem. You can find it here. That is the personal space of one of the Anaconda developers. For additional information on using an updates.img with the installer, see Anaconda/Updates.

If you cannot use the installer patch, to work around the issue, you must either rebuild the array, losing all existing data in the array, or perform the installation without kickstart. Fully manual installations do not exhibit the issue. The inability to reuse existing arrays is limited to kickstart installations only.

Kickstart installations cannot reuse existing LVM volume groups

link to this item - Bugzilla: #503681

Kickstart installations which attempt to reuse existing LVM volume groups (volgroup --useexisting) will fail with an error that the volume group name is not recognized. Anaconda does recognize (and can use) LVM physical volume partitions, but cannot reuse their membership in any existing volume groups. Semi-automatic kickstart installations with manual layout also exhibit the issue.

An installer patch updates.img image is (presently) available which should fix this problem. You can find it here. That is the personal space of one of the Anaconda developers. For additional information on using an updates.img with the installer, see Anaconda/Updates.

If you cannot use the installer patch, to work around the issue, you must either recreate the group, losing all its existing logical volumes and the data they contain, or perform the installation without kickstart. Fully manual installations do not exhibit the issue. The inability to reuse existing volume groups is limited to kickstart installations only.

Kickstart installations fail when using partition options --ondisk or --biosdisk

link to this item - Bugzilla: #504687

Kickstart installations which use either the --ondisk or --biosdisk options to the part kickstart command will not work. A workaround for Fedora 11 is to avoid using either kickstart options. If use of the options --ondisk or --biosdisk is required, an updates.img is available to work around the defect. For additional information on using an updates.img with the installer, see Anaconda/Updates.

Installer sees no hard drives on ppc970 systems

link to this item - Bugzilla: #504040

There is a problem with yaboot on ppc970-based systems which causes the installer to be unable to find the system's hard drives. This prevents installation or upgrade from working.

There is a fix for yaboot, but the fixed package is not present on the Fedora 11 media. However, an updated installer image with this bug fixed is available. The image was built by Fedora contributor and Red Hat employee Josh Boyer and is hosted on his space on the Fedora People server. You can use the image as you would any other boot.iso image, to install from a network source or from a Fedora 11 image or disc. See the installation guide for more details.

Installation fails with LVMError: lvcreate failed for vg_gx2701/lv_root

link to this item - Bugzilla: #496760

There is a problem while creating logical volumes during installation. The steps to reproduce this failure were originally verified prior to release of Fedora 11. Since the release, it appears there may be new failure vectors for this same issue. If you are experiencing this failure, you will need to reboot your system and retry the installation. Root cause for this issue is being investigated.

Writing installation failure tracebacks to a USB key does not work

link to this item - Bugzilla: #491700

In some circumstances, when installation fails and the installer (Anaconda) offers to write the traceback to a USB key for debugging purposes, this does not work properly. Even after inserting a key, it may not be shown in the list Anaconda presents. If you experience this problem, try removing and re-inserting the USB key; this may circumvent the problem.

This bug was fixed after the release of Fedora 11. As it is an installer bug, an update to fix it cannot be provided.

Installer ignores incomplete BIOS RAID array disks, nodmraid kernel parameter not honored

link to this item - Bugzilla: #499733

In Fedora 11, a deliberate change was made to the installer (Anaconda) in the case where a BIOS RAID array is present but the metadata for the array is incomplete. In past releases, the individual disks from the array would be available in the installer. In Fedora 11, they are ignored. This change is intentional. However, a kernel parameter - nodmraid - which should override this behaviour in the case where you wish to install to the disks is supposed to be available, but does not work. This is a bug.

Another way to address the problem - actually preferred to using nodmraid - is to remove the incomplete metadata by running the command dmraid -rE on the array in question. Please backup your data before attempting to do this. Please see the bug report for further discussion of this issue.

Hardware-related issues

General note about updating system BIOS and device firmware

link to this item

Some bugs can be resolved by updating the system BIOS and the firmware on some devices. Always make sure you have the latest versions applied before reporting a bug. Examples of devices which may have firmware updates available include CD/DVD drives and external storage devices such as firewire drive enclosures.

Miscellaneous problems with Intel graphics adapters

link to this item

Many users are already aware from coverage in the press that significant changes have recently been made to the driver for Intel graphics adapters (and the supporting code in Mesa/DRI and the kernel), and that these have caused some functionality regressions. If you are suffering from problems with an Intel graphics adapter such as failure of X to start at all, hangs or freezes or crashes in the graphical environment, display corruption, failure of 3D accelerated applications to work properly or similar problems, and your issue is not specifically covered elsewhere on this page, the following general advice may be of use.

Several such issues may be worked around by disabling kernel mode setting. To do this, add

These legacy acceleration methods will be removed in future, so any bugs in the new acceleration method (UXA) need to be fixed.

Miscellaneous problems with ATI / AMD graphics adapters

link to this item - Bugzilla: #498457

As with the Intel driver, the Radeon driver for ATI / AMD graphics adapters is going through substantial changes, and it is worth noting some configuration options that may help address various problems with such adapters. If you are experiencing failure to start the graphical desktop, hanging or freezing, corruption, or slow performance with an ATI / AMD graphics adapter, you may try the following.

Some issues may be worked around by disabling kernel mode setting. To do this, add

Resume from suspend fails with NVIDIA graphics adapters

link to this item - Bugzilla: #459323

Resuming from suspend fails to restore the graphical display when using the nouveau video driver, which is now the default for all NVIDIA video adapters in Fedora 11. Unfortunately, there is no workaround for this problem, and it is not likely to be fixed within the Fedora 11 timeframe. If you have a system with an NVIDIA video adapter on which you need suspend/resume functionality, you must use an alternative driver. The old nv free driver will work for some cards, but for others, only the proprietary nvidia driver will work. To switch to the nv driver, you can use the system-config-display utility - on the Hardware tab, click the Configure... button next to Video Card and select the nv driver from the list.

Graphical desktop failing to start or crashing with AGP NVIDIA graphics cards

link to this item - Bugzilla: #490358, Bugzilla: #487456, Bugzilla: #498579, Bugzilla: #499730

Problems have been reported with several NVIDIA AGP graphics cards, with the new nouveau graphics driver used in Fedora 11. AGP is a tricky case that the driver does not yet handle well for several cards. If you experience failure to start the graphical desktop (X server), or hanging or crashing of the graphical desktop, and you have an NVIDIA-based AGP graphics card, you may want to try the following workaround. Add the kernel parameter nouveau.noagp=1. For many reporters, this resolves the problem.

Some NVIDIA onboard graphics chipsets use AGP, as well as expansion cards that fit in an AGP slot. To check whether your onboard chipset is an AGP one, run this command:

grep -i agp /var/log/Xorg.0.log

if it returns anything, your chip is an AGP one. If not, it isn't.

If you experience a problem of this kind, and your graphics card is not the same model as in any of the existing reports listed above, please file a new bug report on the xorg-x11-drv-nouveau component, explaining your symptoms, and providing all the usual information required for X.org bug reports.

Grey lines appear in Firefox location bar and terminal windows with Intel i845 graphics adapters

link to this item - Bugzilla: #502096

In a default configuration, on systems with Intel i845 graphics adapters, you may notice graphical corruption of the Firefox location bar, GNOME terminal windows, and possibly other applications. The corruption manifests as one pixel tall, dotted light grey lines of varying widths in random locations, appearing and disappearing. Disabling kernel modesetting, using the nomodeset parameter, works around this issue.

Enabling desktop effects causes system hang with Intel i845 graphics adapters

link to this item - Bugzilla: #490005

On systems with Intel i845 graphics chipsets, attempting to enable accelerated desktop effects (Compiz) via the System / Preferences / Desktop Effects menu entry causes the system to hang (in fact, X is stuck, but if you have the appropriate network setup, you should be able to ssh into the affected machine to shut it down in an orderly fashion). There is no known workaround for this issue, therefore we advise not trying to enable desktop effects on this graphics chipset for now.

Garbage displayed in several applications on systems with Intel i845 / i855 graphics adapters

link to this item - Bugzilla: #505962

Multiple users have reported garbage being displayed in various applications - including but probably not limited to cheese, eog, gthumb, xmgrace, mplayer, emacs, gthumb, blender and inkscape. It seems to be applications that render images or video which are problematic. To workaround this issue, edit /etc/X11/xorg.conf - see this page for instructions on how to create it if it does not exist - and add this line to the Device section:

Option "Tiling"        "False"

Then restart the system (or just X).

Corrupted display in Google Earth on Intel i855 graphics adapters

link to this item - Bugzilla: #XXXXXX

In a default configuration, on systems with Intel i855 graphics adapters, Google Earth does not display properly, rendering only a small, empty black rectangle (and hence obviously being useless). Disabling kernel modesetting with the nomodeset kernel parameter may work around this issue.

Screen stays black when returning from idle mode on Thinkpad X41T

link to this item - Bugzilla: #489907

On the Lenovo / IBM Thinkpad X41T model laptop, with default settings, the screen will fail to turn back on once it has gone into power-saving idle mode (either on a timeout, or on closing and re-opening the lid). Disabling kernel modesetting via the nomodeset kernel parameter works around this problem, but may cause other problems to occur instead. Another workaround is to create a file with the following contents:

#!/bin/bash
xrandr --output LVDS1 --off
xrandr --output LVDS1 --auto

Make it executable, and set a shortcut key combination to launch it. Running the script via the shortcut should restore the display. Fedora developers are currently working on a fix for this problem.

Graphical installation / desktop fails to start on Asus Eee Top

link to this item - Bugzilla: #491627

It has been reported that with a default configuration, Fedora 11 fails to initialize the graphical desktop (X server) properly on the Asus Eee Top system. You can work around this issue by downloading this file and installing it as /etc/X11/xorg.conf. With this file in place, the X server should start correctly at the native resolution of the system.

Graphical installation / desktop fails to start on Mac systems with Intel 945 graphics adapter 8086:27A2

link to this item - Bugzilla: #494390

Several users of various Apple Mac systems, including some generations of the Mac Mini and Macbook, which all use an Intel 945 graphics adapter with the PCI ID 8086:27A2, have reported that the graphical installation / desktop (X server) fail to start correctly. Some users report that disabling kernel modesetting, with the kernel parameter nomodeset, works around this issue.

This issue has also been reported as freedesktop.org bug #21710, and was subsequently resolved in kernel 2.6.31 (as the problem is in part of the driver that comes within the kernel). We are investigating the possibility of backporting this patch for a future Fedora 11 kernel update.

Graphical installation / desktop fails to start on Toshiba Portége M100

link to this item - Bugzilla: #500544

It has been reported that starting the graphical environment (either during installation or on boot of an installed system) fails entirely with default configuration on the Toshiba Portége M100 system. To work around this issue, add the nomodeset kernel parameter, which disables kernel modesetting. With this parameter set, things should work fine.

Graphical installation fails to start on ATI / AMD graphics adapters (especially onboard graphics)

link to this item

On some ATI / AMD graphics adapters - especially onboard adapters (IGPs) - graphical installation may fail to work even if you disable kernel modesetting according to the general ATI / AMD instructions above. In this case, try switching to the fallback vesa driver, by adding xdriver=vesa as a kernel parameter for the installer. If this issue affects you, you will likely need to both disable kernel modesetting and switch to the XAA acceleration method, according to the general ATI / AMD instructions above, if you wish to use the native driver on the installed system (you can switch from vesa to the native driver once the installation has completed using the system-config-display tool).

Slow 3D performance on ATI / AMD graphics adapters

link to this item

The use of kernel modesetting is known to have an adverse impact on 3D performance for ATI / AMD graphics adapters. If you notice poor 3D performance (and better 3D performance is more important to you than smooth graphical boot), disabling kernel modesetting should improve this somewhat. To disable kernel modesetting, add nomodeset as a kernel parameter.

Garbage displayed in some 3D games and applications on ATI / AMD graphics adapters

link to this item - external reference

The GL_EXT_framebuffer_object OpenGL extension is not currently implemented by the 3D driver for ATI / AMD adapters in Fedora 11. This will result in garbage rendering in any game or application which uses this extension. This is a known limitation of the current implementation of the driver: it is being worked on by the driver developers and future updates may make this extension available again.

Installer crashes when Xorg is launched due to ACPI

link to this item - Bugzilla: #507715

ACPI problems are known to cause a crash when Xorg is launched by the installer. Using the kernel parameter acpi=off disables ACPI.

PulseAudio-based volume control cannot adjust volume satisfactorily

link to this item - Bugzilla: #497966 (tracker)

Fedora 11 introduces a simplified, PulseAudio-based GNOME volume control applet and Sound Preferences application: see the release notes, section 4.5 Multimedia, for more details on this.

This, and other PA-based volume controls like pavucontrol, rely on PulseAudio to set the volume level. In some cases where the underlying ALSA volumes do not default to sensible values, PulseAudio-based volume control applications cannot properly adjust the volume: for instance, you hear no sound even with the control set to max, or setting the control to its lowest level still results in audible sound.

In these cases, you can use the legacy volume control application installed by default in Fedora 11 to control the underlying ALSA volumes directly. It can be found in the menus under System / Preferences, with the name Advanced Volume Control. If you upgrade from Fedora 10 to Fedora 11, this volume control application may not be installed: install the package Package-x-generic-16.pnggst-mixer to gain access to it.

If you find yourself in this situation, please file a new bug report on the pulseaudio component, according to these instructions, and set it to block the bug AlsaVolume.

Sound Blaster Live! cards (and other emu10k1-based cards) default to digital (S/PDIF) output

link to this item - Bugzilla: #496320

Due to an oversight in the logic for deciding what input/output profile is best, PulseAudio defaults to digital (S/PDIF) output for emu10k1-based sound cards in Fedora 11. This includes many Sound Blaster Live! sound cards, and several others. For many users this will result in the card apparently not working - you will hear nothing when playing back sound. This is because most users use analog rather than digital connections for their speakers or headphones. To switch to analog output, install the pavucontrol package, and run the program (you can run pavucontrol directly, or look in the system menus under Sound & Video for PulseAudio Volume Control). Go to the Configuration tab, and in the drop-down menu for the affected sound card, change to the 'Output Analog Stereo + Input Analog Mono' option. This should cause sound playback to work correctly. The PulseAudio developers are currently working on an update to fix this issue, which should be available shortly after Fedora 11 is released.

Xorg fails to start when using the nvidia kernel module

link to this item - Bugzilla: #489078

Some users have reported that when attempting to use the "nvidia" kernel module (either the official installer or kmod-nvidia*) Xorg will fail to start properly. The end result, Fedora 11 boots to a black screen. Inspection of dmesg may reveal many messages similar to:

$ dmesg | grep vmap
vmap allocation for size 4198400 failed: use vmalloc=<size> to increase size.
vmap allocation for size 4198400 failed: use vmalloc=<size> to increase size.

A workaround is to add an entry to your kernel line in /etc/grub.conf that includes the amount of video memory on your nVidia card, for example for a 128 MB Geforce 8400 GS you would append the following:

vmalloc=128MB

Synaptics touchpad edge scrolling fails to work on Acer Aspire One

link to this item - Bugzilla: #502548

Acer Aspire One laptop users have reported a regression in regards to the touchpad edge-scrolling feature. There is no known workaround for this problem.

An updated xorg-x11-drv-synaptics package has been submitted to the updates-testing repository for testing. Users experiencing this problem are encouraged to test this update and report to Bodhi whether it solves the problem. To test the update, run this command:

su -c 'yum --enablerepo=updates-testing xorg-x11-drv-synaptics'

Software issues

Network doesn't connect

link to this item - Bugzilla: #498207

After installation, it might be noticed that programs requiring the network can not connect to the network. If this is the case, the NetworkManager icon may show a red X indicating that the machine is not currently connected. While all networking hardware is correctly wired, and device indicators show the network to be properly connected, a change in default install behaviour means that the network does not immediately connect.

The required procedure from this point is to click the NetworkManager icon, and activate the System eth0 or similar connection. If the red X disappears from the NetworkManager icon, then this was the issue that was stopping the connection from being activated.

However, the above change is only for the current login. To make this change permanent, right click the NetworkManager icon, Edit connections, select the System eth0 or similar, click Edit, provide the root password, check the Connect automatically item at the top of the dialog box, Apply and Close.

Please also see the future release note describing this, and a graphical description of the steps to take to make this setting.

Resume from suspend fails, kernel oops notification appears on reboot

link to this item - Bugzilla: #499651

Several users have reported a failure to resume from suspend on various systems. On some systems this happens every time, on others it is quasi-random. When attempting to resume from suspend, the system hangs at a black screen. On rebooting, you are asked to report a kernel oops - ending with [<c040945f>] sysenter_do_call+0x12/0x34 - to the kernel bug tracking system (unless you have this feature disabled).

A workaround for this issue is discussed in the bug report. Create a file /etc/pm/sleep.d/00-cpuspeed.sh with the following contents:

#!/bin/bash
if [ "$1" == "suspend" ]; then
  service cpuspeed stop
  modprobe -r acpi_cpufreq
fi
if [ "$1" == "resume" ]; then
  service cpuspeed start
fi

Make sure it is executable. This should work around the problem on future suspend cycles. We are working to investigate a fix for this issue.

System pauses during boot for over a minute at 'Starting udev'

link to this item - Bugzilla: #513448

If you have a floppy drive controller in your system that is enabled in the BIOS, but no actual floppy drive, you may be affected by an issue where the boot process pauses for a significant time (at least a minute). If you hit the Escape key to see verbose boot messages, you will see that it hangs at the 'Starting udev' stage. There are two known workarounds for this issue. Either disable the floppy drive controller in your system BIOS, or blacklist the 'floppy' module in Fedora: create a file named /etc/modprobe.d/floppy.conf, with the contents:

blacklist floppy

ALSA sequencer unavailable by default

link to this item - Bugzilla: #505421

Due to a misconfiguration, in Fedora 11, the snd-seq module - which provides the ALSA sequencer interface - is not loaded by default. This affects applications which use the sequencer, such as Package-x-generic-16.pngqjackctl - "Could not open ALSA sequencer as a client", "ALSA MIDI patchbay will not be available" - and Package-x-generic-16.pngtuxguitar.

To work around this problem, create a file with the following contents:

install snd-pcm /sbin/modprobe --ignore-install snd-pcm && /sbin/modprobe snd-seq

and save it as /etc/modprobe.d/dist-alsa.conf.

An updated module-init-tools package has been submitted to the updates-testing repository for testing. Users experiencing this problem are encouraged to test this update and report to Bodhi whether it solves the problem. To test the update, run this command:

su -c 'yum --enablerepo=updates-testing module-init-tools'

Non-Fedora Mozilla/Firefox binaries may crash

There is a conflict between binary software downloaded from Mozilla and software included in Fedora which may lead to a crash, often seen when using Flash. See details and workarounds.
