I wanted to create a virtual display for Sunshine and came across this article. It looks like no one has linked it here before 🙂
Something I noticed recently is that Sunshine has added support for XDG Portal Screenshare access, meaning on KDE you can actually screen share a virtual display without needing anything configured on the hardware. You need to use the xdg-portal capture method, but I’ve tried it out with my phone before
You need virtual dislay so that meat that you don’t connect video card to TV. Maybe best choice - use wolf? No DE, no display. Just GPU and podman.
Interesting tech! But my use case was to stream my desktop 🙂
Hmmm.
I have an issue with my media PC where if it’s turned on before the HDMI connected TV, then we can’t see the display… I wonder if this will fix that issue too by pretending the TV is always connected…
Oh interesting. I’ve been doing this with a dummy HDMI plug for ages, and sure don’t fix what isn’t broken, but it’d be nice to set it up entirely virtually.
I’ve done both ways and the dummy plug is much less hassle in my opinion. Not a universal solution though. My GPU has only one HDMI port.
I found this article nearly a year ago and have been using this method since, it works great. I use it to play games at my phone’s weird native resolution, and my wife uses it to play games at her macbook’s weird native resolution.
I also have multiple systemd-boot configs to boot with or without it.
Hey this sounds pretty great! I’m going to give this a shot.
Pretty dope idea! Might try this out soon!
