I switched from Ubuntu 16.04.2 LTS to Ubuntu GNOME 16.10 two weeks ago, and it was working fine. But for some reason, if I upgrade to 17.04, it gets stuck on the login screen. That is, after I click my user account and enter my password, it gets stuck on the grey screen. The mouse pointer doesn't move. And, I can't start a tty. But, I can lock the account by pressing Ctrl + Alt + F1. But when I try unlocking it by entering my password, same problem again. This only happens on 17.04 for me. 16.10 works fine.

I got the same problem with ubuntu 17.04 on a fresh install. The issue was the graphical part (nvidia/intel on board), so on the login I :
Install nvidia driver and nvidia prime
Switch from nvidia to intel in a terminal
When using nvidia, it was ok!
