Created attachment 124523
  --> https://bugs.freedesktop.org/attachment.cgi?id=124523&action=edit
Contains crash dump and xrandr --verbose output

Display froze.
I could still move the mouse cursor but couldn't have any interaction on opened
windows, toolbar, menu...
I did a Ctrl+Alt+F2 to get a console and here is dmesg output :


[drm] stuck on render ring
[drm] GPU HANG: ecode 0:0x00200000, in cubestorm [6409], reason: Ring hung,
action: reset
[drm] GPU hangs can indicate a bug anywhere in the entire gfx stack, including
userspace.
[drm] Please file a _new_ bug report on bugs.freedesktop.org against DRI ->
DRM/Intel
[drm] drm/i915 developers can then reassign to the right component if it's not
a kernel issue.
[drm] The gpu crash dump is required to analyze gpu hangs, so please always
attach it.
[drm] GPU crash dump saved to /sys/class/drm/card0/error
[drm:i915_hangcheck_elapsed] *ERROR* Hangcheck timer elapsed... render ring
idle
SELinux: initialized (dev fuse, type fuse), uses genfs_contexts


The crash dump is attached to the bug.
Thanks for your help.
