So for those who are now reaching the login screen and cannot login even when you type in your password. SSH into your rig and run the following commands:
sudo apt-get purge nvidia*
sudo dpkg --configure -a
sudo shutdown -r now
Now everything's working back to normal. Not sure why it did that for me. Also, I don't know if the first commmand is necessary, it's just what I typed in initially so I included it.
Thanks so much for this. I don't think the first command is necessary (edit: just to get your rigs running - see below, it may be for stability) - just the second got everything running for me. When I ran the first command, I then had to do:
sudo apt-get install nvidia-385
So to get my remote-rigs running again I just had to:
sudo dpkg --configure -a
sudo reboot
