--- Comment #14 from Jan Papež (honyczek) honyczek@centrum.cz --- (In reply to comment #13)
- Disable acceleration (Option "NoAccel" "True" in the device section of your xorg.conf)
- Disable Tiling (Option "ColorTiling" "False" in the device section of your xorg.conf)
Is possible to add these options when using KMS? Modifying /etc/X11/xorg.conf.d/*.conf is enough?
