General bug reports

If you are experiencing a problem with Xorg, the following would be useful to attach to your bug report (individually, uncompressed, with MIME type set as text/plain):

  • /etc/X11/xorg.conf (or, if this file does not exist, specify in the bug report that it does not)
  • X server log file(s) /var/log/Xorg.*.log
  • /var/log/Xorg.0.log from a trial run where you move /etc/X11/xorg.conf aside and let Xorg autodetect your hardware (if you have such a file).

KMS problems (most Intel and AMD/Radeon hardware)

Please add drm.debug=1 to the kernel command line (in /etc/grub.conf), reboot and attach /var/log/messages to your bug report.

Additionally, please add nomodeset to the kernel command line and try to reproduce the problem, and include the following information :

  • if you were able to reproduce the problem or not
  • X server log file(s) /var/log/Xorg.*.log

to your bug report as well.
