It seems the problem was two fold: There was a hidden in /lib/linux-restricted-modules/ that confused Xorg byt thinking it had the wrong driver version. I ran: sudo rm /lib/linux-restricted-modules/.nvidia* and it fixed that problem.
The second problem was that GLX and Direct Rendering wouldn't load. That was caused by the XGL package still being installed. I removed all XGL packages and the problem was solved. I suggest that the update script should check for both of these problems, as it will probably be very common for people upgrading from Feisty to Gusty! -- [Gusty] Broken Nvidia driver after upgrade to Gusty (7.10) https://bugs.launchpad.net/bugs/138933 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
