Doing the workaround worked! Here is what I did 1) ALT+F1 (to get to console) 2) stopped gdm 3) unloaded modules radeon drm 4) reloaded modules radeon drm 5) ALT+F7 to get to xwin .. logout 6) start gdm
The order is a little clumsy .. but it just worked after I did this. So the problem is how the radeon drm module is being loaded. -- [gutsy] Regression - "Desktop effects could not be enabled" on ATI Mobility Radeon https://bugs.launchpad.net/bugs/144077 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
