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!
