I restarted my Ubuntu 14.04, and it brought up the login screen so I logged in and there was nothing but a black screen. I searched the web and tried about 15 fixes, but nothing worked.

Something similar to this happened before: I was stuck in a login loop (I would login, the screen would flash, and the login screen would come up again). The only solution I found for that was a re-install of the OS, which I really can't afford to do again (I have a site that runs off this computer and I need to have it up again).

Help is greatly appreciated!

  • I have an Nvidia GT 610. I've done apt-get purge nvidia*, but that hasn't seemed to help.... Also, if I do sudo start from tty, I get the desktop, but without the menu bars and stuff, just the background and the files on my desktop... @Ashu

  • Thank you! It worked! Note: just doing the driver thing as you suggested didn't work by itself. It seems that I had also lost ownership of my Xauthority file. It worked by using sudo rm ~/.Xauthority after reinstalling the drivers.
