I have this bug. I updated to 9.04 rc2 and it worked fine for a day or two. Then I updated something, and after boot I got nvidia kernel mitmatch with 180 and 185 (I was using 180). I then tried to reinstall nvidia-glx-180, but after removing it if I try to install the package, all the xserver packages would be removed.
The included log shows this. ** Attachment added: "aptlog.txt" http://launchpadlibrarian.net/25872708/aptlog.txt -- Latest Xorg removes nvidia driver ... conflicting xserver-xorg-video-4 https://bugs.launchpad.net/bugs/308410 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
