Take a look at this thread in the forums:
http://ubuntuforums.org/showthread.php?t=1501156
one temporary workaround i found was to comment out a part of /etc/init/gdm.conf
after a week of working very well, the problem came back and now ubuntu goes directly to text login.
I think this is part of a larger issue in init or gdm and not an issue with nvidia.
