Public bug reported:

Hybrid laptop with an NVidia 960M video card boots to a black SDDM
screen when the NVidia card enabled (using the NVidia 384 and 390.xx
drivers).  Nouveau drivers fail to boot.

Switching to Intel drivers (sudo prime-select intel), SDDM loads/runs
just fine.

Removing the "quiet" option from grub boot shows Simple Display Manager
starting without error when NVidia is enabled.  Unsure how to provide
additional useful information.

Ctrl-Alt-f1, logging in via the terminal, and startx enables normal
desktop use.
