Thanks for reporting this bug. ATI has released a newer fglrx with a fix for this issue.
I've packaged the fglrx driver, and put the debs up for testing on Gutsy: http://people.ubuntu.com/~bryce/Testing/ I notice in the changelog, that the new fglrx has fixes for this exact problem. Josh Andler has this bug with fglrx and has confirmed that with these debs, it goes away. Still, additional testing on Gutsy would be much appreciated. These are the packages I installed in my tests: fglrx-control, xorg- driver-fglrx, fglrx-kernel-source, linux-restricted-modules-common, linux-restricted-modules-2.6.22 Also turn off Composite if you have it on (fglrx doesn't support it) I've heard it needs to be turned off by setting Option "Composite" "0" rather than "Disable", but have not confirmed this. fglrxinfo and glxgears are useful to verify things are working properly. ** Changed in: linux-restricted-modules-2.6.20 (Ubuntu) Status: Unconfirmed => Fix Committed -- System hangs on restart/shutdown with current fglrx driver loaded! https://bugs.launchpad.net/bugs/94849 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
