npras42, try this. Worked like a charm for me.
Edit: It quit on me again. I've been fighting with this for a couple of weeks now, done with ubuntu.
ok, I didn't quit on it
. After his step where you reboot and get to the login, I did the ctrl+alt+f1, then 'sudo /etc/init.d/gdm stop, then 'sudo apt-get dist-upgrade'.
Downloaded the new 9755s from nvidia and installed. All appears
to be well at the moment...we'll see.
