Yep, having the same problems here also, with a dual monitor set up. Works fine without compiz, but with compiz the screen gets corrupts. Symptoms including random garbage over monitors, to just a black screen where the background should be, and dragging windows leaves a trail of artifacts as if the background is not being rendered at all.
My graphics card chipset is ATI Radeon X800XT. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/776565 Title: compiz no longer able to drive my external monitor on upgrade to 11.04; does not recover -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
