[Bug 1785761] [NEW] Selecting proprietary driver seems to have no effect

[Yann Salmon]

Public bug reported:

I am trying to activate nvidia-driver-390 for my graphics card instead
of nouveau. The graphical interface of the Driver Manager detects my GPU
and the available drivers but selecting nvidia-driver-390 seems to have
no effect (the packages have already been installed but nouveau is still
used).

Running kcmshell5 kcm_driver_manager in the console enabled me to get
the following messages. Usage was to select nvidia-driver-390 and click
Apply.
