Okay, I had the idea, that it is a problem of the driver. Good. I've done all with this page from OpenSuse-Wiki: http://de.opensuse.org/SDB:AMD/ATI-Grafiktreiber#Installation_via_makerpm-ati-Skript And now I want to uninstall the driver. So, I go in my terminal and become root with: su Then I give the following command: ./makerpm-amd-12.1.sh -u And then comes this error report: Check for running this script as root ... [ OK ] Check for correct runlevel to remove AMD Catalyst 12.1 ... Current runlevel: 5 Error: The system is in wrong runlevel. Please switch to runl [ FAILURE ] I know, this is not a problem for a wine forum, but maybe someone can help again? What is a runlevel, and how I change it to uninstall the driver? Thanks for all answers Greetz IceNekromant
