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.

    Almost exactly the same problem here, and no answers found. Difference is that I installed Ubuntu GNOME 17.04 dual boot with Ubuntu 16.04 LTS. 16.04 still runs fine, in fact the 17.04 GNOME Live CD ran fine until install.

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 :

  • Switch to a terminal with Ctrl+Alt+F1
  • Install nvidia driver and nvidia prime

    sudo add-apt-repository ppa:graphics-drivers/ppa
    sudo apt-get update
    ubuntu-drivers devices
    sudo apt-get install nvidia-(number) nvidia-prime

  • Switch from nvidia to intel in a terminal

    sudo prime-select intel
    sudo prime-select nvidia

When using nvidia, it was ok!

I had the same issue today. I wasn't even able to use CTRL + ALT + F1/F3 to use a terminal only. So after many restarts I tricked it login to recovery mode from which I did yet another release upgrade to Ubuntu 17.10. 17.10 does not have issue like this one and the GUI is smoooth as a butter!
