mrg, this bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? If so, could you please test for this with the latest development release of Ubuntu? ISO images are available from http://cdimage.ubuntu.com /daily-live/current/ .
If it remains an issue, could you please run the following command in the development release from a Terminal (Applications->Accessories->Terminal), as it will automatically gather and attach updated debug information to this report: apport-collect -p xserver-xorg-video-ati REPLACE-WITH-BUG-NUMBER Please note, given that the information from the prior release is already available, doing this on a release prior to the development one would not be helpful. Thank you for your understanding.

The system will freeze for a second or two whether compositing is on or off when certain user interface functions are called. Xorg CPU usage is 100% and takes priority from other system processes. The mouse will not respond and if audio is playing it will stutter. User interface functions affected are: window switching (changing focus), window open, scroll frame, viewing an image Functions NOT affected: window minimize/maximize, desktop cube, present windows, most effects This bug occurred in previous ubuntu version 9.10 but was fixed with the workaround: Option "MigrationHeuristic" "greedy" in xorg.conf This option no longer has any effect. These options improve scrolling speed/smoothness on GTK based applications only. Option "EXANoUploadToScreen" "1" Option "EXANoDownloadFromScreen" "1" To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-ati/+bug/577288/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : [email protected] Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
