This bug appears to involve a freeze of Xorg, probably due to a GPU
lockup in the kernel drm code, in a version of Ubuntu before
natty (or we couldn't determine the version from the report).
The X team has been investigating GPU lockups in Intel's video driver
during the natty development cycle.
I tried the upgrade and downgrade xserver-xorg-video-intel package, with no
success.
The only thing that works is using karmic kernel 2.6.31.
