** Description changed:

  TEST CASE:
  1. Monitor compiz CPU usage (from /proc/<pid of compiz>/stat or top in batch mode)
- 2. In "brightness and lock" settings set "Turn screen off when inactive" to 1 minute" 
+ 2. In "brightness and lock" settings set "Turn screen off when inactive" to 1 minute
  3. Wait until screen turns off
  4. Move mouse or press a key to turn screen back on
  5. Check the CPU usage from the monitor
  
  ACTUAL RESULT:
  When screen turns off compiz goes to 100%
  When the screen turns back on, cpu usage drops immediately to a normal value
  The graph attached shows %CPU of compiz with a sample per second. The graph has been captured on a system with  a Radeon HD5770 and fglrx if that matter
