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.
