I installed Ubuntu Gnome 14.04 LTS a couple of days and and was installing everything I needed. I installed the Displaylink drivers and then was in the middle of configuring my monitors when I was randomly kicked out into the login screen and got stuck in a login loop.
I still have access to the CLI and have tried a couple of things to get it working. Tried installing a different login manager (lightdm), didn't work. Tried re-installing gdm, didn't work. Made a new user, which worked, however, I added the new user to the same groups as my previous user (Sudo permissions included), turned off my computer and the next time I turned it on and attempted to login I got stuck in the same login loop with the new user.
Any other suggestions to try and get it working? or do I just have to re-install the OS?
