The driver works properly. However, the configuration is what's at issue (therefore an apt problem). The configuration that's forcible enforced in the xorg.conf.d directory doesn't take into account that some devices have dual video cards. My issue was that there is an onboard Intel video chipset and also a NVidia discrete video adapter in my laptop. The kernel detects Intel and NVidia video cards and loads the Intel drivers... When the X-Windows system loads it detects the NVidia video card and attempts to load the X-Server system for it, but the underling modules haven't been loaded into the system and therefore loads the the black screen.
If you go into the xorg.conf.d and modify the 10-nvidia.conf files to add the [Option "PrimaryGPU" "true"] line then it works, but because these files are not configured in the package as configuration files they are overwritten on every update. -- 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: Invalid Status in nvidia-graphics-drivers-390 package in Ubuntu: Confirmed Status in sddm package in Ubuntu: Confirmed 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.
