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 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 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1752053 Title: nvidia-390 fails to boot graphical display To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/mesa/+bug/1752053/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
