Hi, I'm trying to get rolling with Bazzite. I've got Proxmox setup as the host, and I've got GPU passthrough working fine for Windows VM clients. The whole thing is headless and I have an HDMI dummy plug attached to the GPU. My typical workflow is to install the client operating system with a virtual display and the GPU attached (2nd display). Then I get sunshine/moonlight setup, and finally I detach the virtual display.
In this case, with Bazzite using the nvidia-open variant, I'm getting black screen when streaming from the built-in sunshine.
