I had this same problem. Using Nvidia 8800gts, previously working perfectly in 9.04.
After upgrade X was broken, booted to CLI with flickering. Once logged in, startx said no screens and xinit no such file or folder. After editing xorg.conf using nano to make X use vesa driver instead, I managed to boot to a desktop. However The first time I did this I got four popup warning messages on the desktop saying critical kernel failure. In the end I had to do a fresh install. -- upgrade breaks graphic drivers and x, preventing login or startx https://bugs.launchpad.net/bugs/464591 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
