Comment 3 for bug 1320868

same thing happen to me even when i try to downgrade to version 304,also i try to install ".run" driver from nvidia website.
to fix my system (12.04 TLS) i have to login as a root in console mode and remove all nvidia files:
apt-get purge nvidia*
then i have reboot my pc and everything was returned to normal especially the screen resolution.
note: i have attached the jockey.log file.
