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 Touch seeded packages, which is subscribed to mesa in Ubuntu. https://bugs.launchpad.net/bugs/1752053 Title: nvidia-390 fails to boot graphical display Status in mesa package in Ubuntu: Fix Released Status in nvidia-graphics-drivers-390 package in Ubuntu: Fix Released Status in xserver-xorg-video-nouveau package in Ubuntu: Invalid Bug description: I'm using Bionic with the new 4.15 kernel. I've been using the nvidia-384 driver with no problem for a while. Today I issued "sudo apt-get upgrade" and I was prompted to upgrade the nvidia driver to the nvidia-390. After installing the driver and rebooting, I was only able to boot in to the tty terminal. The graphical display failed to boot. I have had similar problems with nvidia driver version 390 with Arch Linux and with Open Suse Tumbleweed.
