Comment 8 for bug 97251

I had this problem as well in Gutsy. I am running with an ATI Radeon X200 mobile chipset. I recently hosed my system and needed to reinstall. I installed the proprietary drivers from the restricted drivers manager but I have NOT enabled desktop effects again.... NOW the problem is NON-Existent I believe that the screensaver/power settings are being turned off by Compiz or are otherwise being disturbed in some form or way. I am sorry that I can't give any more info but it has to be the effects or a combination of the driver/effects. hopefully this will help the devs...
