Same problem here with a Dell XPS 15 9560 after Kubuntu 17.10 -> 18.04 upgrade. Finally solved after lots of retries and reboots. I have now: Graphics Drivers PPA (https://launchpad.net/~graphics-drivers/+archive/ubuntu/ppa) - sudo add-apt-repository ppa:graphics-drivers/ppa - sudo apt update - sudo apt dist-upgrade Replaced manually nvidia 390 drivers by the newest 396 Purged nouveau package because I saw a "segmentation fault" log in /var/log/Xorg.0.log - sudo apt purge xserver-xorg-video-nouveau - sudo vi /etc/X11/xorg.conf -> uncomment line #Driver "nvidia" of Section "Device". So my xorg.conf file is exactly the same as the pasted in comment #77 without the last Section "Monitor". - sudo reboot
After the reboot I see my previous sddm login screen instead of a tty and I can login normally :) -- 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
