Context: I am trying to passthrough my iGPU to a QEMU/KVM VM. When I do so, my laptop screen goes black, which tells me that the mux switch that my laptop has isn’t used
Makes sense I guess, since I’m using Reverse PRIME to render everything with my dGPU!
So my question is, how can I use my dGPU to render everything on the host (I had issues with hybrid graphics) and have the output go through the mux directly so that I can passthrough my iGPU without an issue? Thanks in advance!
xorg conf that I use to use dGPU with everything
