Hello. Updating the drivers from xorg-edgers launchpad repository seems to fix my problem. At the moment I did not get back graphics corruptions in KDE/qt apps. I updated this packages:
xserver-xorg-video-ati xserver-xorg-video-radeon xserver-xorg-core libgl1-mesa-dri libgl1-mesa-glx libdrm-radeon1 libdrm2 The launchpad xorg-edgers: https://launchpad.net/~xorg-edgers/+archive/ppa Important parts of my xorg.conf are: Section "Module" Load "glx" Load "dri" EndSection Section "Device" Identifier "Configured Video Device" Driver "radeon" Option "AccelMethod" "EXA" Option "DRI" "on" EndSection Section "DRI" Mode 0666 EndSection I suggest that If you have fix the problem by updating the packages, keep the drivers installed but disable xorg-edgers repositories. Otherwise, having a worse performance, remove the xorg-edgers repositories from sources.list, uninstall the packages that have been updated, do a "apt-get update" and re-install them. To date, the version of drivers that I mentioned are “6.12.99+git20090729” Bye. -- [M24] Kubuntu: corrupted graphics, choppy scrolling https://bugs.launchpad.net/bugs/338628 You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-ati in ubuntu. _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
