I managed to mostly solve the problem; on page 5 of the link paxman1 posted (http://kubuntuforums.net/forums/index.php?topic=3098015.60) someone named ilowman suggested going to System Settings->Advanced->Service Manager and turning off "Detecting RANDR (monitor) changes"
The effect was immediate; my screen now flickers only when loading KDE4.1, and when opening System Settings->Display. This seems to solve the glitches where the screen briefly redraws in a shifted position from normal; the people at that link seemed to think there are two kinds of graphical glitches going on here. One downside, however, is that while I can still switch screen resolutions to 1024x768 (and possibly others) I cannot switch back; I lost my first draft of this comment when X restarted instead. -- [Intrepid] Screen flicker/resync on X4500HD https://bugs.launchpad.net/bugs/275152 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
