This is a very common dpms problem that was fixed just recently in the intel driver, and the regression was introduced in the "Sync DRI2 CopyRegion to vertical retrace" commit on 6/02 that snuck into karmic. If you want to test the fix, please add this PPA to your sources and pull in all of the upgrades.
