now I rewert to clean (ie stable) xorg-6.8.1 build from source.
(but I do not change drm module... it look like xorg source do not contain
drm sources) this not help much :( quake crached after a minute or
two. only garbage on the screen and locked mouse... but Xserver itself not
locked I can shutdown Xserver by keyboard... coredump for quake2 not
generated regardless I set ulimit -c unlimited
but there is a message in the log of running quake2:
Error: R200 timed out... exiting
What I can do farther? any ideas?
can this problem be related to drm module?
what other drm modules I can try ?
