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.

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:

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.
