First I've tested manual installation (by letting the Catalyst installer create deb-packages), then I tried the packages from https://launchpad.net/~ubuntu-x-swat/+archive/x-updates .
Both variations had the same problem: After enabling KDE desktop effects (KDE 4.5) the PC freezes. Changing to terminals or something else isn't possible any more, Alt+Print+R/E/I/S/U/B was the only solution. There are no errors in Xorg logs. Re-creating the configration with aticonfig and amdcccle didn't solve this.
Besides: Starting glxgears openes a glxgears windows with the gears standing still. The window neither can be closed by pressing CTRL+C on the terminal nor by calling "killall -9 glxgears". Pressing the "X" in the windows title bar closes the window but the terminal doesn'tt return to prompt and "ps" shows glxgears as still running. Again no errors in Xorg.0.log.
The desktop effects (and glxgears) worked using the driver from July.
Some system information:
- Kubuntu Lucid 10.4.1 x64, all recent updates installed
- KDE 4.5 installed
- X.org 1.7.6
- Installation and creation of the driver showed no errors
Forgot to mention: It's a AMD HD 4290 (integrated chipset)
