Tried also installing lightdm instead of gdm3 which just get me a dark screen.
Reverted back to Nouveau drivers doing what Ivan did in #78, I managed to do a startx and get into gnome desktop. Then I rebooted, and gdm3 was just fine and managed to login.
But after another reboot I could just access to gdm3 but system seemed hangs after login (fixed cursor in middle of a dark screen). If I play with alt+ctrl+f1 , f2 It turns back to gdm3 login screen. alt+ctrl+f3 gets me to a standard text login.
I managed to properly boot again after doing a sudo dpkg-reconfigure gdm3 but it worked only once.
Finally, out of desperation, I did another sudo apt-get install nvidia-driver-396 and now everything is working :) Go figure...
My guess is that removing the old xorg.conf file did the trick for me
Having more or less the same bug as anybody here, but with final Bionic 18.04.
I tried what proposed on #29 and #47 => installing from ppa : https:/ /launchpad. net/~graphics- drivers/ +archive/ ubuntu/ ppa without success (either 390 or 396 version of drivers) without success
