My Ubuntu 14.04 LTS Desktop was working fine until I decided to play around with Google Two Factor Authentication for Linux.
I followed instructions and setup the google-authenticator.
When I restarted, the machine had a loop on login screen - after entering password and OTP from Google App, login screen was being displayed again.
I removed google-authenticator, uninstalled lightdm, installed Gnome, did "chown $username:$username ~${username-home}", but nothing has worked.
Any ideas?
