X stopped responding to mouse and keyboard.
Partial dmesg output:
[11759.532741] [drm] stuck on render ring
[11759.532812] [drm] GPU crash dump saved to /sys/class/drm/card0/error
[11759.532815] [drm] GPU hangs can indicate a bug anywhere in the entire gfx
stack, including userspace.
[11759.532817] [drm] Please file a _new_ bug report on bugs.freedesktop.org
against DRI -> DRM/Intel
[11759.532819] [drm] drm/i915 developers can then reassign to the right
component if it's not a kernel issue.
[11759.532825] [drm] The gpu crash dump is required to analyze gpu hangs, so
please always attach it.
