Bug Description
Binary package hint: xserver-
jaunty x86_64, xserver-
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_
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)
Update: it also only crashes if dri(?) is in use: if I shut off compiz (which is used by default) with "metacity --replace", the X server then survives console switches.
In particular this causes suspend/resume to fail because the power manager tries to chvt to a text console on suspend.
syslog excerpt:

Feb 15 13:34:15 hostname gdm[22637]: WARNING: gdm_slave_
nothing shows up in Xorg.0.log
