For GPU lockup bugs with Intel graphics, you need to collect the output
of 'dmesg' and your /sys/kernel/debug/dri/0/i915_error_state file. Both
of these must be collected while the machine is locked up (e.g. by
sshing into the sick machine over ethernet). See
https://wiki.ubuntu.com/X/Troubleshooting/Freeze for additional info.

Title:
X hard lockup in raring, can't even switch VTs
Status in “xserver-xorg-video-intel” package in Ubuntu:
Incomplete
Bug description:
After an upgrade to raring, I've experienced a bug where firefox and X
are each consuming a CPU doing nothing useful. When this happens, I
can still log into the machine remotely with no problems, but the
console is completely frozen. The X cursor doesn't move, unity
doesn't respond, windows are not refreshing, and I can't even change
VTs (from the keyboard, or over ssh - if I run 'sudo chvt 1', it
hangs).
It appears that X and firefox are both busy, but strace of firefox
shows no output. kill -9 of the firefox process also has no effect
(bug #117499). There is nothing logged in dmesg or in the X log that
seems relevant.
After debugging this for about an hour, the firefox process spontaneously
died, at which point X also stopped monopolizing the CPU; but the console was
still frozen, A few minutes later, the VT switch request seems to have
registered and I wound up on VT1. However, switching back to VT7 does not
result in the screen being refreshed, and 'sudo chvt 1' again hangs.
