I also reported this in the KDE bugzilla and they say the same, the drivers are probably guilty: https://bugs.kde.org/show_bug.cgi?id=208106
however I was using GNOME+compiz without any problems on this hardware in quite some past versions of ubuntu (including 9.04). I don't have GNOME installed right now on my computer to check though. But yes, it's probably a problem with the drivers. ** Bug watch added: KDE Bug Tracking System #208106 http://bugs.kde.org/show_bug.cgi?id=208106 -- kwin desktop effects black desktop https://bugs.launchpad.net/bugs/433173 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
