* '''2010-07-05''' Updated


The [http://eeepc.asus.com/global/ EeePC]  has really taken the sub-compact pc market by storm.  Although the bundled linux installation is interesting, Fedora is more our style.  This page should contain all the needed quirks and notes needed to run Fedora perfectly on the eeePc.

Using USB pendrive (at least 1 GB) take a look at the [[FedoraLiveCD/USBHowTo| USB Howto page]]


* '''2008-02-14''' [http://www.redhatmagazine.com/2008/02/14/fedora-eee-pc-eeedora/ Red Hat Magazine: Fedora + Eee PC = Eeedora]
Using the regular installation DVD may be problematic when putting it on USB flash drives. Use the livecd versions.


== ACPI State of play==
'''Recommended for resource limited netbooks'''
* Out of the Box F8: The asus_acpi module that Asus provided provides ACPI events that can be handled by the acpid daemon.  Asus provides scripts that the acpid can trigger to do various functions, Volume Up, Volume Down, Wifi On/Off etc.  Asus also provides their OSD code to notify the user that they have pressed a button.
* Out of the Box F9: Fedora 9 ships with a module called eeepc.ko - if you load it at system boot (add modprobe eeepc to /etc/rc.local) pressing one of the extra buttons will generate an acpi event that you can (and have to) handle yourself.


* This is how I got the Fn+F2 (wireless) hotkey working on Fedora 9 with networknanager: [http://forums.fedoraforum.org/forum/showpost.php?p=1005336 Link] .
http://spins.fedoraproject.org/moblin/


* Goal: I plan to provide an asus_acpi module that gives proper Fedora system integration through HAL.
http://spins.fedoraproject.org/xfce/
* Status:  Thanks to [http://blog.eikke.com/index.php/ikke/2007/08/15/asus_laptops_multimedia_keys_and_input code]  [http://blog.eikke.com/index.php/ikke?cat=17 Ikke]  started, I got things in order quite quickly.
=== Buttons ===
* Zz/Fn+F1 - Works as expected computer suspends
* Wifi/Fn+F2 - Currently produces the wlan ButtonPressed event on dbus.  I am working on hal killswitch functionality for it.
* BrtUp/Fn+F3 - Works.  No OSD
* BrtDown/Fn+F4 - Works. No OSD
* SwitchDisplay/Fn+F5 - Produces ButtonPressed events on dbus.  My plan is to patch [http://dekorte.homeip.net/download/grandr-applet/ grandr]  to listen on the dbus and do proper xrandr switching.
* AP/Fn+F6 - AccessPoint Mode?  I don't think we need this.  I was thinking about making this button use xrandr to switch on and off a scrolling Virtual Display.  This should help if a large dialog box pops up off screen. (Originally this Fn Key was meant to open the task manager)
* Mute/Fn+F7 - Works. OSD. Needs tweaks to gconf
* VolDown/Fn+F8 - Works. OSD. Needs tweaks to gconf
* VolUp/Fn+F9 - Works. OSD. Needs tweaks to gconf

Green: works<br>
Yellow: should eventually work<br>
Red: non-free drivers or serious hardware support problems
 
==== Eee PC 90x/1000H/1005HA/1005PE/1015PEM/1015PN Series ====
 
The XXXp models (like the 1005p) are based on newer Pine Trail platforms. Issues may arise as newer models are released.
 
Fn Keys (included wireless switch) o
* Almost working, the Fn+F2 (wireless switch) mostly works; supported by eeepc_laptop kernel module.  May require 'acpi_osi=Linux' to be added to kernel boot parameters for eeepc_laptop module to load. The system doesn't always connect right away when re-enabled by HW switch (~1 minute delay).
 
Wireless chipset
* Eee PC 901/1000H wireless chip is Ralink RT2860, which is not supported by current kernel (work on support is in progress, see [http://rt2x00.serialmonkey.com/wiki/index.php/Main_Page rt2400] project page for more details), but there's an open source driver provided by Ralink. RPMFusion has a kmod package with this driver (kmod-rt2860). [https://fedoraproject.org/wiki/OtherRepositories Read this for more details on external repositories].
* 1001p/1005p wireless chip is Atheros AR2427 802.11g WiFi supported by ath9k but needs 2.6.32+ kernel.
* 1015PEM wireless chip is Broadcom BCM4313. Drivers are availible in RPMFusion (package b43-fwcutter or wl kernel module). In recent kernel versions (around 3.1) also brcmsmac became ready and available.
 
Video Card ION (1015PN)
* Works properly with nouveau driver
* To be able to switch between video cards, follow [http://f4l3.net/2011/07/make-ion-working-properly-in-fedora-15 this] tutorial.
 
Issues
* Fn Key to disable wireless also disables eth0 [fix: what model?]
* Screen is off after resume from suspend/hibernate (Eee PC 901) - upgrade to BIOS 1603

===== Brightness Issues =====
With some Eee PC's, the brightness setting are either too low, or are sometimes a little inconstant or arbitrary (inconsistent on each boot, eg. high to low/completely off).
If you have issues with this, issue this command to fix it:


        fi
<pre># setpci -s 00:02.0 f4.b=80
        ;;
esac
</pre>
Make scripts executable:
<pre>
chmod -v +x /etc/acpi/actions/*
</pre>
</pre>


== Wireless Drivers ==
The <code>80</code> represents the desired range for brightness in hexadecimal, where <code>FF</code> allows to maximum brightness. <code>80</code> is about half and is generally ideal but may need to be tweaked to suit one's need.
Livna-testing has working madwifi drivers
 
Note this is not permanent, so it should be added to rc.local.


<pre>
File:<code>/etc/rc.d/rc.local</code>
su
<pre>#!/bin/sh
rpm -ivh http://rpm.livna.org/livna-release-9.rpm
rpm --import /etc/pki/rpm-gpg/RPM-GPG-KEY-livna
</pre>


This will compile a kernel module everytime is necessary... So feel free to update your kernel when fedora team releases updates.
...
<pre>
yum --enablerepo livna-testing install akmod-madwifi
</pre>
On first new kernel boot, it will compile the new kernel module..when finished, reboot and wifi will work! That's all!


setpci -s 00:02.0 f4.b=80</pre>


''If you want to compile manually the madwifi driver, use the experimental one:''
= Hints and alternative software =
===== Maximize battery life =====
<ol>
<li> Use the integrated HPET timer (saves about 30 CPU wake ups per second)


First install all necessary packages:
Should be used by default.
<pre>
su
yum install make binutils gcc glibc-devel glibc-headers libgomp patch kernel-headers kernel-devel wget
</pre>


Blacklist the ath5k module:
<pre>$ cat /sys/devices/system/clocksource/clocksource0/current_clocksource</pre>
<pre>
echo "blacklist ath5k" >> /etc/modprobe.d/blacklist
</pre>


Look at your modprobe.conf:
This should return 'hpet'
<pre>
gedit /etc/modprobe.conf
</pre>


Your /etc/modprobe.conf should look like this:
<li> Change IO scheduler to deadline:
<pre>
Load the module.
<!-- Start Atheros Stuff
<pre># modprobe deadline-iosched</pre>
-->
alias wifi0 ath_pci
alias ath0 ath_pci
options ath_pci autocreate=sta
<!-- End Atheros Stuff
-->
</pre>


Download madwifi-nr-r3366+ar5007 driver:
Edit /boot/grub/menu.lst
<pre>
wget http://snapshots.madwifi.org/special/madwifi-nr-r3366+ar5007.tar.gz
</pre>


Extract madwifi source code and compile it:
Add 'elevator=deadline' to kernel options.
<pre>
tar xvf madwifi-ng-r2756-20071018.tar.gz
cd madwifi-nr-r3366+ar5007
make && echo ok
su -c "make install && echo ok"
</pre>


== NetworkManager ==
<pre>$ cat /sys/block/sda/queue/scheduler</pre>
''Not necessary in Fedora 9''
This should return 'noop [deadline] cfq'
* Works well with the Madwifi-NG drivers.  To solve problems with frequents drop outs and communication problems try issuing this command.
<pre>
iwpriv ath0 bgscan 0
</pre>
* Just a quick update on a better way to issue this command on every boot.  Edit your /etc/modprobe.conf and change change your lines for ath0 to look like this.
<pre>
alias ath0 ath_pci
install ath_pci /sbin/modprobe --first-time --ignore-install ath_pci && { /sbin/iwpriv  ath0 bgscan 0 > /dev/null 2>&1 || :; }
</pre>


== Window Manager ==
<li>Run powertop as root and do the recommended changes. Changes do not stick and have to be run again after a reboot.
Do yourself a favor and install [http://icculus.org/openbox/index.php/Main_Page Openbox] .
<pre># dnf install powertop</pre>
<pre>
yum install openbox obconf
</pre>


After installation you will need to choose openbox as your new window manager.
<li> Disable rarely used services
If you are running gdm click on the session button and choose Gnome/Openbox.  If
you have an .xinitrc that is run at log in you can add, openbox, openbox-session
or openbox-gnome-session to it.


Why?
<pre># for s in abrtd atd auditd avahi-daemon ip6tables iscsi iscsid mdmonitor portreserve livesys livesys-late; do echo "chkconfig $s off"; chkconfig $s off; done</pre>
* This Window Manager is FAST!!!
* The decorations are very small and simple.
* By default Openbox trys to shrink windows to fit the viewable screen
* Did I say this how fast this WM is?


== Resolutions ==
<li>Install Jupiter and Jupiter Support/Eee from [http://sourceforge.net/projects/jupiter/ SourceForge] to add power profiles as well as extra function keys and automatic support for Super Hybrid Engine.
== Wireless resume from suspend fix ==
With madwifi driver, wireless doesn't work when resuming from sleep...but we can fix this issue with this script


Create the file:
Download the latest jupiter and jupiter-support-eee RPM packages from SourceForge.
<pre>
su -
gedit /etc/pm/sleep.d/S99wireless
</pre>
and paste this code:
<pre>
#!/bin/sh


case "$1" in
<pre>sudo dnf clean all
thaw|resume)
sudo dnf install --nogpgcheck /path/to/jupiter*rpm /path/to/jupiter-support-eee*rpm</pre>
{ ip link set wifi0 up ; } 2>/dev/null
;;
*)
;;
esac
exit $?
</pre>


( Please Note that the machine won't suspend if the radio is turned off and the Madwifi driver is still loaded. )
</ol>


Make the script executable:
===== Maximize performance =====
<pre>
chmod +x /etc/pm/sleep.d/S99wireless
</pre>


== Quirks ==


=== Shut down fix ===
<ol>
If your EeePC does not entirely shutdown, add the following line to '''/etc/init.d/halt''' (I put right after the "Saving mixer setting" stuff):
<li> Noatime for hard drive (reduces writes to disk)


<pre>
<pre>nano /etc/fstab</pre>
su -
gedit /etc/init.d/halt
</pre>


add this line just before the '''# Save random seed block'''
Add ",noatime,nodiratime" after "defaults" for all ext2,ext3,ext4 partitions.


<pre>
<li>Remove Pulseaudio (when playing music or watching video pulseaudio can raise CPU usage high)
#Shutdown eeepc fix
modprobe -r snd-hda-intel && echo "snd-hda-intel module removed!"
</pre>


Bug has been reported: https://bugzilla.redhat.com/show_bug.cgi?id=444115
<pre># dnf remove pulseaudio</pre>


=== TouchPad ===
Switch audio preferences to ALSA.  Video players also need to be changed to ALSA in audio properties.


To enable the touchpad tapping, make your /etc/X11/xorg.conf look [http://forums.fedoraforum.org/showpost.php?p=1012733&postcount=16 like this] .
<li>Turn off unnecessary services on start up.


Should usually be found in Preferences -> Startup

Eee PC 90x/1000H/1005HA/1005PE/1015PEM/1015PN Series

The XXXp models (like the 1005p) are based on newer Pine Trail platforms. Issues may arise as newer models are released.

Fn Keys (included wireless switch) o

  • Almost working, the Fn+F2 (wireless switch) mostly works; supported by eeepc_laptop kernel module. May require 'acpi_osi=Linux' to be added to kernel boot parameters for eeepc_laptop module to load. The system doesn't always connect right away when re-enabled by HW switch (~1 minute delay).

Wireless chipset

  • Eee PC 901/1000H wireless chip is Ralink RT2860, which is not supported by current kernel (work on support is in progress, see rt2400 project page for more details), but there's an open source driver provided by Ralink. RPMFusion has a kmod package with this driver (kmod-rt2860). Read this for more details on external repositories.
  • 1001p/1005p wireless chip is Atheros AR2427 802.11g WiFi supported by ath9k but needs 2.6.32+ kernel.
  • 1015PEM wireless chip is Broadcom BCM4313. Drivers are availible in RPMFusion (package b43-fwcutter or wl kernel module). In recent kernel versions (around 3.1) also brcmsmac became ready and available.

Video Card ION (1015PN)

  • Works properly with nouveau driver
  • To be able to switch between video cards, follow this tutorial.

Issues

  • not supported by default, no packages in rpmfusion, no drivers in staging tree. This is a Realtek RTL8192SE chip, incompatible with RTL8192E and RTL8192SU drivers already in staging.
  • vendor-supplied free drivers may or may not work, depending on your kernel version and system CPU architecture
  • you may have luck with a rtl8192se_linux_2.6.0010.1116.2009 driver on 2.6.31.5 or 2.6.31.9 kernel on x86_64 architecture.

Fixes and solutions to common problems

FN keys not working

eeepc_laptop is not loaded. Edit /boot/grub/menu.lst. Add 'acpi_osi=Linux' to the kernel options.

# lsmod|grep eee

eeepc_laptop should be listed in the results.


Hiding the battery broken alert

This fixes the annoying battery broken alert reported by gnome-power-manager on login. That's a known bug

$ gconftool-2 --type bool --set /apps/gnome-power-manager/notify/low_capacity 0
Brightness Issues

With some Eee PC's, the brightness setting are either too low, or are sometimes a little inconstant or arbitrary (inconsistent on each boot, eg. high to low/completely off). If you have issues with this, issue this command to fix it:

# setpci -s 00:02.0 f4.b=80

The 80 represents the desired range for brightness in hexadecimal, where FF allows to maximum brightness. 80 is about half and is generally ideal but may need to be tweaked to suit one's need.

Note this is not permanent, so it should be added to rc.local.

File:/etc/rc.d/rc.local

#!/bin/sh

...

setpci -s 00:02.0 f4.b=80

Hints and alternative software

Maximize battery life
  1. Use the integrated HPET timer (saves about 30 CPU wake ups per second) Should be used by default.
    $ cat /sys/devices/system/clocksource/clocksource0/current_clocksource

    This should return 'hpet'

  2. Change IO scheduler to deadline: Load the module.
    # modprobe deadline-iosched

    Edit /boot/grub/menu.lst

    Add 'elevator=deadline' to kernel options.

    $ cat /sys/block/sda/queue/scheduler

    This should return 'noop [deadline] cfq'

  3. Run powertop as root and do the recommended changes. Changes do not stick and have to be run again after a reboot.
    # dnf install powertop
  4. Disable rarely used services
    # for s in abrtd atd auditd avahi-daemon ip6tables iscsi iscsid mdmonitor portreserve livesys livesys-late; do echo "chkconfig $s off"; chkconfig $s off; done
  5. Install Jupiter and Jupiter Support/Eee from SourceForge to add power profiles as well as extra function keys and automatic support for Super Hybrid Engine. Download the latest jupiter and jupiter-support-eee RPM packages from SourceForge.
    sudo dnf clean all
    sudo dnf install --nogpgcheck /path/to/jupiter*rpm /path/to/jupiter-support-eee*rpm
Maximize performance
  1. Noatime for hard drive (reduces writes to disk)
    nano /etc/fstab

    Add ",noatime,nodiratime" after "defaults" for all ext2,ext3,ext4 partitions.

  2. Remove Pulseaudio (when playing music or watching video pulseaudio can raise CPU usage high)
    # dnf remove pulseaudio

    Switch audio preferences to ALSA. Video players also need to be changed to ALSA in audio properties.

  3. Turn off unnecessary services on start up. Should usually be found in Preferences -> Startup
