I went to 'System'>'Preferences'>'look and feel'>'windows manager' and got the following error: "window manager 'unknown' has not registered configuration tool" I restarted metacity in the terminal and then from 'Personal'>'Sessions' I selected 'automatically remember etc'. Then I realized that desktop-effects (which was working very well prior to the update) was not working anymore (no cube and no wobble). I tried to enable it and got the following error in the terminal: Fatal: No GLXFBConfig for default depth, this isn't going to work. compiz (core) - Error: Failed to manage screen: 0 compiz (core) - Fatal: No manageable screens found on display :0.0 Version-Release number of selected component (if applicable): How reproducible: Always Steps to Reproduce: 1. 'desktop-effects' in terminal Actual Results: Expected Results: Additional info:
I have updated to the latest version 2.6.24.3-34.fc8 which appears to have fixed the issue. Most likely the problem was related to the DRM issue which seems to have been fixed in this kernel release.
