What are the usual troubleshooting steps if the display stays black?
I solved most of my issues from my post Need help with gpu passtrough
I added some kernel parameters, blacklisted drivers (followed the instructions for the amdgpu on the archwiki).
sudo dmesg does not give me any error messages anymore(related to the gpu (I think?)) but now everything shows up in my primary display again(when I set pci=nomsi and from what I can tell the driver loads with the gpu properly). Running gnome-shell or xorg.sh runs and does not crash but does not display much (sometime completely bugged windows on the primary display). The display connected to the GPU only flashes when starting or powering the VM off.
No Idea what I should do jus’t cant get anything to my other display.

I mean it’s loaded correctly right? So I should be able to just start a X session right?
