Hallo Alberto! I found the time do delete the Catalyst drivers (AMD installer) and reinstall fglrx from the repositories. I also reinstalled ubuntu-drivers-common from the proposed-archive just to make sure.
Some testing showed the following results: Configuration via "sudo aticonfig --adapter=all --initial -f" is successfull. Amdcccle shows the right graphics cards information. The discrete card is activated by default. But when I switch cards via amdcccle or aticonfig the X-Server crashes at restart with error: "No matching device section for instance (BusID PCI:0@0:1:1)" Rewritting the xorg.conf with aticonfig makes the X-Server startable again. This error also appeared with the drivers from the AMD installer before. The gpu-manager still does not seem to be working. Should the /var/log/gpu-manager normally be rewritten on each boot? That's definitely not the case, according to the last modification time. Can you give me any advice on how to find out what could possibly be blacklisting gpu-manager or stopping it from working? When I start gpu-manager manually the log gets rewritten. Could the X-server-crash be linked with the deactivated gpu-manager? Once again thanks a lot for your work. It's highly appreciated!
