I purged gnome but when I'm at the login screen I can only log in with gnome: if I try to change shell everything is blank. Logging in with gnome lead to a black screen and I can't even open the terminal.
When running
sudo apt-get install ubuntu-desktop
I get the same results as this I tried those answers with no luck. I also tried all the solutions and various command lines here without finding a solution.
I would like to get the standard Ubuntu shell, I don't use unity.
