Public bug reported:
Binary package hint: xserver-xorg-video-intel
jaunty x86_64, xserver-xorg-video-intel xserver-xorg-video-intel
2:2.6.1-1ubuntu2
00:02.0 VGA compatible controller: Intel Corporation Mobile GM965/GL960
Integrated Graphics Controller (rev 0c)
(pci id 8086:2a02) - lenovo x61 tablet.
The X server crashes with:
Feb 14 18:26:26 hostname kernel: [ 252.148399] [drm:i915_gem_execbuffer]
*ERROR* Execbuf while VT-switched.
whenever a console switch happens (either by ctrl-alt-Fn or by chvt command.)
It does not crash on console switch if UXA is not enabled via Option
"AccelMethod" "UXA" in Device section of xorg.conf. (however without
UXA, graphics performance is very bad)
In particular this causes suspend/resume to fail because the power
manager tries to chvt to a text console on suspend.
