I just upgraded from ubuntu 16.04 to 17.10, when logging in, I have three options:
Ubuntu on Xorg
GNOME on Xorg
However, I can only login using unity, the other two options make the screen turn black and then it goes back to the login screen.
I haven't been able to find much information on this issue, however, I think it may be related to my laptop having a Nvidia graphics card. Any ideas on what might be the problem?
