Describe the Bug

I have igpu AMD 610M, installed drivers under PikaOs (ubuntu with game optimizations) VM under Proxmox. I use Sunshine on same server with Windows VMs without problems. One time while I connected via vnc it worked but very slow. When I disable vnc session and server and tried to connected directly. I have monitor connected to HDMI and dummy plug. With both I get error of not able to detect display.
Installed sunshine through Flatpak. How can I start while startup?

I tried command with setcap. same result.

Expected Behavior

It open session with display or dummy plug connected, same as on Windows VMs
If amd igpu drivers failed than use software encoding. But software encoding is not available.

For software encoding you can use Xvfb to create a virtual display. I don't know how well this will work, but we use it in our unit tests to verify the software encoder passes the basic tests.
