Bug#924704: bumblebee-nvidia: nvidia-driver 410 doesn't appear to allow the unloading of the nvidia module

[Danfun360]

I already tried legacy-390xx. As I said before, there doesn't seem to be
equivalents of nvidia-cuda-toolkit and nvidia-cuda-dev that don't try to
force the latest nvidia drivers. Also, bumblebee doesn't recognize the
legacy-390xx drivers as a GLX alternative (I get an error stating such).

If I was to remove bbswitch, would I be unable to use PRIMUS? Also how
would I go about with my VGA Passthrough setup?
