After a number of mystical reinstalls, I finally got the Nvidia driver working again. Along the way, I reinstalled nvidia-glx-new and nvidia- kernel-common, which did not seem to help the problem. I also let some nitwit talk me into "m-a a-i nvidia", which installs obsolete drivers in the kernel, but I managed to back that out after hours of painful hair- pulling.
In the end, I think it was the reinstall of linux-restricted-modules that made it work, but I had thrashed the machine so much that I seriously doubt I could come close to duplicating the process. Anyway, if your Nvidia drivers are hammered like mine were, try reinstalling linux-restricted-modules, then nvidia-glx-new, then nvidia-kernel- common. Maybe the elves will make shoes for you. -- 8.04 System Update hammered Nvidia restricted drivers https://bugs.launchpad.net/bugs/431131 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
