Problem with nvidia-installer-dkms on hybrid graphics booting to black screen

Correct, but only if Nvidia driver is installed of course.

For dedicated graphics only, one has the option to switch Intel off in the bios, but need to black list nouveau. This works for me:

Then the alternative is to install optimus-manager and switch back and forth between Intel or Nvidia card on laptop. When it works it is ok, but graphics can be glitchy.
