** Description changed:

+ SRU Justification
+ 
+ Impact: when changing resolution X hangs due to GPU hangs
+ 
+ Fix Description: handles the case where the cursor is off the active
+ area, ensuring the cursor ends up valid; an invalid cursor can lead to a
+ GPU hang
+ 
+ Patch: TBA
+ 
+ Risks: non-affected systems may be impacted by the change which is in
+ generic i915 code.
+ 
+ TEST CASE: Place the cursor in the bottom right and reduce resolution
+ 
+ ===
+ 
  NOTE: the machine is not necessarily hung as in some cases the use
  reports being able to see the logout dialog from the power button
  (albeit all corrupted), there are also results of ssh'ing into the
  machine.

  Binary package hint: xserver-xorg-video-intel
  
  When changing the resolution  on a Fujitsu Siemens Esprimo and a Fulitsu
  Siemens 24" display, the X server is hung with colored graphic blocks.
  
  Steps to reproduce:
  1) Open gnome-display-properties
  2) Select 1680x1050 or 1024x768 (instead of 1900x1200)
  3) Screen may either turn black or start to flicker or both happens after each other
  
  From the system itself only a hard power off is possible. It may be
  accessible via ssh but it cannot be tested because of a restricted
  testing environment.
