Hello,

i have a working setup to run a gaming vm with windows 10. My pc has 2 gpus (r9 
380 and gtx 1080) and i run the vm with the nvidia card which is binded to the 
vfio driver.

Now i want to use the nvidia card on my host too (arch linux). Usual gpu 
offloading with PRIME works fine, while the gpu is binded to the nvidia driver. 
Changing the driver back to vfio and again to nvidia works too, BUT i cant do 
this rebinding procedure while my gpu is claimed by xorg. (xrandr 
--listprovides show 2 providers).

I guess i have 2 options now, rebinding the gpu to vfio while claimed by xorg 
or using tools like bumblebee/nvidia-xrun to create a second xorg session with 
my nvidia gpu.

Using bumblebee did not work for me, it complained about not finding an igpu (i 
would like to use it with the amd card if possible...)




Any ideas how i could set that up?
Maybe someone is running a similar setup.

Thank you!
