Optimus AMD + NVidia

[RossComputerGuy]

I've got an Alienware M15 R5 Ryzen Edition which has an RTX 3070, unfortunately I get an error when Bumblee's daemon starts: [ 487.307327] [ERROR]No integrated video card found, quitting.. The problem is that it seems Bumblebee only checks for an Intel integrated GPU. I don't see any issues open or close about this so I'm opening this one.

I currently use this patch to run bumblebee with AMD CPUs:

You will also have to patch bbswitch to use it as a backend:

Of course the proper way to do this would be to add a command line/kernel parameter to determine which id to use at runtime.

Is there any progress on this? Any plans to support this officially?
