Xorg log
This is a regression that happened somewhere between Ubuntu 12.04 and Ubuntu
13.04. The package versions are linux-image-3.8.0-19-generic 3.8.0-19.29,
server-xorg-core 1.13.3-0ubuntu6, and xserver-xorg-video-intel 2.21.6-0ubuntu4.
This is x86_64.
The graphics device is:
00:02.0 VGA compatible controller [0300]: Intel Corporation 2nd Generation Core
Processor Family Integrated Graphics Controller [8086:0102] (rev 09)
I'm seeing frequency (~1x/day) complete hangs of X. Switching VTs and
switching back partially fixes it, but graphics are a little bit glitchy
afterwards (in particular, emacs leaves little bits of its caret all over).
dmesg says:
[ 4331.543286] [drm:i915_hangcheck_hung] *ERROR* Hangcheck timer elapsed... GPU
hung
[ 4331.543290] [drm] capturing error event; look for more information in
/debug/dri/0/i915_error_state
Xorg says:
(EE) [mi] EQ overflowing. Additional events will be discarded until existing
events are processed.
Full logs and error state are attached.</pre>
