Great to see it helped!

Many thanks, I will look into this.

I really love your project but couldn’t get it up and running on Bazzite due to only supporting podman out of the box. Do you know of a good guide for Bazzite?

Maybe you have to wait for Artemis/Apollo becoming available for Linux. They seem to be looking into Linux support.

I wrote a tutorial that might be of interest to you:

It describes setting up Sunshine on Bazzite without a HDMI dongle. Hope this helps.

Do they now have Linux support? I thought this was limited to Windows as host at this time?

I first had it running with the kernel parameters. For this see the second link in the introduction. The problem there was it added to boot time, as the kernel generates an error message. Passing an EDID as kernel parameter was complicated, due initramfs modification being tricky on Bazzite (at least acccording to my limited understanding). So I moved to this method where I initialize the virtual display via the KMS debug API later in the boot process. This can also be used to arbitrarily modify the virtual display. I have not looked into doing it via parameter. Can you share the example commands?
