Can I use NVIDIA-PRIME on a non-Ubuntu Debian system? If not, how do I use my NVIDIA card without Bumblebee?

I have Bumblebee installed but it has a number of problems, not the least of which is being unable to use Vulkan. I tried following the instructions here , in addition to running # apt remove bumblebee*. I rebooted and was able to login with lightdm, but after that the display was black, so I reverted the changes using a different session not running X. Is there something I should do not spelled out in that linked page? It seems like it was written for those trying to set up their NVIDIA-optimus stack, not modify it. I'm running Deepin 15.4.1, which is based on Debian Sid, with slightly different package repositories.
