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"
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
