Hello friends
I was using EL7 on gnome 3 for few months without any problem. Even 2 hours
ago I had the computer (Laptop running on Nvidia-Prime) turned on and
everything was working without flaw. But when I turned on the computer few
minutes ago, I got login screen (which does not usually happen, since I
have autologin turned on) and when I entered my login credentials I got
black screen and went back to login screen. Everytime I entered my
credentials the same thing happened so I was stuck in endless login loop.
At first I thought it was caused by gnome-extension I updated to new
version today.
For me, I noticed (on a different terminal - Ctrl+F2) that when I warm
boot the laptop, the Nvidia Card is not recognized and hence I get that
login loop. When this happens, I simply fully shutdown laptop for a
minute and when I boot up again, the card is found and all is well. I
might as well mention that I'm running Ubuntu 16.04 on my laptop so your
problem might be different but just thought I might mention it just in
case...

I used to do exactly like you - drop to shell and start messing with
stuff until I realized that this is what was happening. My workaround
has been to simply shutdown, wait a minute and reboot - works always!
