Thank you for reporting this bug. It's possible that this is the same
issue as bug 511001, but we prefer to keep xorg bugs separate until
proven otherwise. The Lucid kernel does not have the infrastructure in
place to troubleshoot GPU hung bugs properly. The intel-drm-next kernel
from [1] (see [2] for more information) has a patch that will dump the
error state to /sys/kernel/debug/dri/0/i915_error_state. Could you copy
this file and attach to this bug report. To get a consistent set of logs
it would be nice if you could copy /var/log/Xorg.0.log and dmesg output
at the same time and attach here.

There is some general information about this kind of bug at [3].
