I had trouble to find the drivers for my gtx 760 under linux.
After the installation of the drivers per nvidia’s official website i typed in my password and i landed on the same page again.
Even the guest user didn’t worked. I always landed on the same login page.
Solution: Driver install via apt
apt-get install nvidia-304 nvidia-304-updates nvidia-settings
When you can’t login you can press STRG + ALT + F1 to get into the command line. Then you type in your credentials and you can remove all old drivers and install the new ones (apt-get remove –purge nvidia*)
