General bug reports
If you are experiencing a problem with Xorg, the following would be useful to attach to your bug report (individually, uncompressed):
/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.0.logfrom a trial run where you move
/etc/X11/xorg.confaside and let Xorg autodetect your hardware (if you have such a file).
See the documentation on the upstream wiki.
