I updated my system (KDE 64 RC1) this morning. After a reboot - the Display Manager wouldn't work. I uninstalled x11-driver-video-fglrx, dkms-fglrx, and fglrx-control-center, then installed the fglrx-legacy ones. The display manager is working again, however, the desktop effects are bad. I used to have wobbly windows, now I have ghost images. I have a RS780L [Radeon HD 3000] integrated card. What can be done?
