I have the same issue with the fglrx driver and an ATI Radeon Mobility HD 4650 graphic card.
When I log in from LightDM to Unity 3D, I have a black screen with some small rectangles of the wallpaper. I can click on the session menu and log out, but windows appear with black areas, just like on the screenshot of #3. Unity 2D session is working good. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/819144 Title: [fglrx] everything is black and blinks when using unity To manage notifications about this bug go to: https://bugs.launchpad.net/nux/+bug/819144/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
