I see the exact same behaviour since upgrading to feisty, although with a slightly older card that needs the 'nvidia' module, as opposed to 'nvidia_new'. I don't remember exactly, but I might have used the nvidia-installer somewhere in the past.
Symptoms are: first it works fine, but after a reboot, X can't start. When I try to load the nvidia kernel module, "modprobe nvidia" says: FATAL: Could not open '/lib/modules/2.6.20-15-386/volatile/nvidia.ko': No such file or directory I can "repair" my ubuntu by doing a sudo apt-get install --reinstall linux-restricted-modules-2.6.20-15-386 after that, sudo /etc/init.d/gdm restart successfully starts X That package doesn't contain the missing file, but reinstalling seems to create it in a way. Of course, it's gone when I boot the system again. I did all the checks mentioned above in this thread and see the same things like kry10. -- nvidia-glx-new: X does not start on reboot.
