Public bug reported:

Binary package hint: xserver-xorg-video-intel

I've had a few OpenGL programs suffer from frozen screens when they use
a full-screen mode on my EliteBook 8440p laptop. So far I have only
found one way to reproduce the problem.

* Launch Kubuntu's "system settings" app.
* In the Display and Monitor control panel, select "Screen Saver", and choose an OpenGL Screen Saver.  I tried Euphoria and Particle Fountain.  Set the screen saver to start after 1 minute.
* In the Power Management control panel, find a profile assigned to the Performance profile. Edit the Performance profile to enable display power management, standby after 2 minutes, suspend after 3 minutes.
* Do nothing for 4 minutes, then touch a key.

For me, the screen lights up showing the last frame of the screen saver
. The cursor is active and changes shape as I move it, as if it were
reacting to the unseen windows on the screen.

Switching to console 1, I see an irregular stream of messages
  [drm:i915_hangcheck_elapsed] *ERROR* Hangcheck timer elapsed ... GPU hung
  [drm:i915_do_wait_request] *ERROR* i915_do_wait_request returns -5

Xorg.log ends with
  [  4163.368] (WW) intel(0): i830_uxa_prepare_access: gtt bo map failed: Input/output error
  [  4163.371] (EE) intel(0): Failed to submit batch buffer, expect rendering corruption or even a frozen display: Input/output error.

The Asciiquarium and Blank Screen screen savers don't cause this
problem.

This may be upstream bug
