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:/
While following these instructions re-installing of nvidia drivers failed. The only things that worked is purging the drivers and changing "WaylandEnable=
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.
