Comment 103 for bug 969860

I'm running Ubuntu 12.10 quantal with the amd-catalyst-13.8 beta2 drivers downloaded from the AMD website and compiled/installed on the system. I've not tried GNOME but I've seen this in the other xsession environments. The primary use of this box is running a standalone xbmc instance though. Whenever the screen is shut off (either by standard delay or xset dpms force off) the cpu usage shoots up to 100%. The card is a Radeon HD 7310
