Thanks Darcy. That's a new one to me, but Google shows a lot of people with the same problem using the fglrx driver.
I know there are installation and uninstallation problems with the fglrx driver causing the wrong GLX libraries to be present and rendering OpenGL useless. Please try: 1. Run jockey-gtk and uninstall the FGLRX Radeon driver. 2. In a terminal, run: sudo apt-get install --reinstall libgl1-mesa-glx 3. Reboot Then you should at least have a clean system and maybe the built-in radeon driver will work for you. If that's not enough then also try: https://wiki.ubuntu.com/X/Troubleshooting/VideoDriverDetection#Problem:_Need_to_purge_-fglrx See also: https://bugs.launchpad.net/ubuntu/+source/fglrx-installer/+bug/855943 https://help.ubuntu.com/community/BinaryDriverHowto/ATI https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/293012 https://bugs.freedesktop.org/show_bug.cgi?id=34846 ** Bug watch added: freedesktop.org Bugzilla #34846 https://bugs.freedesktop.org/show_bug.cgi?id=34846 ** Package changed: unity (Ubuntu) => fglrx-installer (Ubuntu) ** Changed in: fglrx-installer (Ubuntu) Status: Incomplete => New ** Changed in: unity Status: Incomplete => Invalid ** No longer affects: unity -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/987584 Title: Cannot access Unity 3D while ATI graphics driver is installed on 12.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/fglrx-installer/+bug/987584/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
