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 have the same problem on a Foxconn Netbox nt525 with Intel GMA 3150.
Have to change to vesa driver to get it working without freezes.

Title:
Some new info. Now I catched several hangs during work with external
monitor connected. Ubuntu 10.10, intel drivers 2.13.901 from glasen
repo.
And finally there's some info in /var/log/messages exactly before hang:
Nov 13 03:29:56 oleg-portable kernel: [51580.271924] *pdpt = 3315c001
And here's even more info (from /var/log/kern.log):
Nov 13 03:29:50 oleg-portable kernel: [51574.269108]
[drm:i915_gem_do_execbuffer] *ERROR* Invalid object handle 0 at index 0
Nov 13 03:29:56 oleg-portable kernel: [51580.271866] BUG: unable to handle
kernel NULL pointer dereference at 0040
Same with version 2.13 of intel drivers. Hangs even when booted from
Maverick's LiveCD.
