Trevor... I need help. I'm afraid I made it worse. Unsure if the same issue that was slowing down my desktop was the same reason I was crashing, I found this post.
and I ran this command from it:
gnome-shell --replace &
I was messing with ensuring nouveau was gone beforehand. I ran
modprobe -r nouveau
shortly before running the above gnome-shell command. That is the only thing I can think of that would have mattered.
After running the gnome command, the machine crashed, and now every time I boot the machine, I get a blank grey login screen. I have found several other posts with similar issues (many of which you responded on. You are quite active, thank you for all of the help).
Do you think this grey screen is graphic driver related? I can get to text mode with ctrl+alt+f2 and I can also sign into the machine through putty.
I have tried reupdating graphics drivers from el repo (seeing a lot of your recommendations that that is better.) Running
sudo yum update $(nvidia-detect)
returns a lot of errors for example:
Error: Package: kmod-nvidia-430.40-2.el7_7.elrepo.x86_64 (elrepo)
Requires: kernel(drm_crtc_send_vblank_event) = 0x4a758854
and at the end of it all
You could try using --skip-broken to work around the problem

Do you have any suggestions? Thank you so incredibly much for all of your help.
