I have a problem that may be the same as yours. I just upgraded to 11.04 from 10.10 and I've tried both Unity and [currently using] Classic GNOME 2. When I mouse over icons in Avant Window Navigator or click indicator- applets, the screen goes CRAZY, crashing emerald my display. I have tried this with no fglrx, the included fglrx and ATI's new drivers, with Compiz and without compiz, with Emerald and with Metacity and it doesn't make a difference. I thought it was a bug with compositing but it seems to happen even when compositing is off. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/769288 Title: Desktop is never stable, always flickering [drm:intel_prepare_page_flip] *ERROR* Prepared flip multiple times -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
