Installing GDM3 does lead to a system which will not boot to a black screen. Note you will need to change the desktop session to plasma to get to kde.
For an experienced user used to the command prompt this is an annoyance. I'd rather run a pure KDE kubuntu system. To a newer or less technical user having a black screen (not flashing cursor BLACK) is a show stopper. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to apt in Ubuntu. https://bugs.launchpad.net/bugs/1765923 Title: Nvidia driver leads to black screen on bionic 18.04 SDDM LightDM bug? Status in apt package in Ubuntu: New Status in nvidia-graphics-drivers-390 package in Ubuntu: New Status in sddm package in Ubuntu: New Bug description: Using the April 19th daily build of Kubuntu 18.04 I installed the Nvidia drivers via the following command. sudo ubuntu-drivers autoinstall The install process proceeds fine and after a logout process I get a black screen. I tried this on the April 17th daily build of bionic and a reboot also results in a black screen. The following is a question which was submitted by a Ubuntu 17.10 user: QUOTE After I installed latest Nvidia driver-390 and tried to boot after shutting down once I faced a black screen problem. since, I'm a noob but something related to nvidia drivers couldn't be started. Then I followed https://askubuntu.com/a/968692/802490 While following these instructions re-installing of nvidia drivers failed. The only things that worked is purging the drivers and changing "WaylandEnable=false" in (/etc/gdm3/custom.conf). Now, I want to re-install nvidia drivers again but I'm afraid that this will lead to that problem again. Can anyone help in re-installing the driver such that I won't face that problem? END QUOTE THE WORK AROUND Use Ctrl-Alt-f6 to get to a login prompt. Login run "startx" The x server will start and Nvidia drivers will function. THE PROBLEM When I try to run SDDM I get an error (Which I will try to copy down to add to this bug when I am on a different computer than the one I am reporting the bug about.). Installing lightDM does not work... it installs but is either will not run or will not actually start a x session.
