@Thijs Kaper: I have the exact same problem. My alternative workaround: Like you I authenticate, black screen after typing the password and hitting enter. Then I go to tty2, authenticate in the terminal, and type 'startx' (and 4 times Ctrl+C). And finally KDE starts without problem on tty2. This is crazy.
Like @Bernadette Addison I had huge icons. It was impossible to set a higher resolution with the KDE display manager. So I used xrandr: xrandr --output eDP-1-1 --mode 1920x1200 --scale 1x1 for example. The resolution is fine even after a reboot. I also want to add that I am actually using the nvidia driver 396.24. Because I had so much problems before... I tried to add the graphics-driver ppa as advised by @Chris McDonough. I do not know if finally this helped me a little. Maybe I should switch back to 390. My graphical interface is really a mess since the upgrade to 18.04 :-( -- 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
