Public bug reported:
In Karmic x86_64 with GM965 graphics, kernel linux-
image-2.6.30-9-generic, xserver-xorg-video-intel 2:2.7.99.1+git20090602
.ec2fde7c-0ubuntu2 I experienced a crash when using the GNOME Appearance
preferences application to switch visual effects from None to Normal.
Compiz and Xorg both crashed. Compiz reported:
compiz.real[5633]: segfault at 18 ip 00007fd09807af01 sp
00007fff78998f00 error 4 in i965_dri.so[7fd098039000+278000]
While xorg said:
Xorg[3609]: segfault at 0 ip 00000000004f14e4 sp 00007fff126238c8 error
4 in Xorg[400000+1c4000]
Xorg also left the following stack trace in Xorg.0.log.old:
