There is a lot of information in the comments of this bug report describing how and when this bug occurs on Lucid, Maverick and Natty. This information, and particularly it's interconnectedness, would be lost if people filed new bugs.

@Bob - Given that you have AMD (ATI) graphics the example /etc/X11/xorg.conf given in this bug's description should help. Alternatively you can a try the profile-based power management method and then set either high, medium or low profile. See comment #19 in bug 557829. See http://www.phoronix.com/scan.php?page=news_item&px=ODIyOA for further info. Please let us know if either of both of these methods work or not.
