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].
