After install nvidia driver gdm3 won't load (blank screen)

[dukercs]

Good morning!

I've upgraded my system from ubuntu 16 LTS to 18.04 LTS and now to 20.04 LTS. I really want to believe that's a good practice. So no I don't tried to reinstall, yet.


I've installed the nvidia with this command:

sudo apt-get install nvidia-driver-418

My journalctl after tried to prime-select nvidia and a systemctl restart gdm3

This is likely the issue. You could rename your xorg.conf to something else, so that you aren't trying to use that ModeLine that you've specified for some reason.
