This happened to me as well, but I only noticed when I was trying to build my own kernel and couldn't (naturally) use the nvidia drivers with the new kernel. I switched to the nv driver, and discovered it failed. I subsequently discovered that it ALSO fails with the 2.6.17-generic kernel Ubuntu came with- apparently the nv driver did not upgrade from 7.0 to 7.1 along with the rest of the xorg xserver.
I was stuck completely in textmode until I installed an nVidia driver. -- xserver does not boot after upgrade from dapper to edgy / abi mismatch of nv nvidia driver https://launchpad.net/bugs/67272 -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
