I’d like to try to get fedora to host a second headless Wayland session in the background for a remote user. I have a GPU but I want to share its render and compute, not the physical HDMI output, so I need a virtual Wayland session for the second seat.
Supposedly logind could handle the seat and udev permission issues clean enough, but headless use is still beyond me there.
I’d like a KDE Plasma environment running headless and then sunshine can just stream this session out using the war capture method. I just don’t know how to start up a separate Wayland session under another linux user in the background with a plasma session drawing to an imaginary monitor.
There seem to be 2 ways of doing this.
- wlheadless-run - a young project made to solve this particular problem
- kwin --virtual can theoretically do this, but I’m not finding clear examples of it

There is also this guide, but it is specific for Xorg and Nvidia gpus. But I suspect that if you replace the
startxhere withstartplasma-waylandordbus-run-session startplasma-wayland, then it will work. It would still be nvidia gpu specific though.that won’t work. that only applies to X11. Wayland doesnt work that way.
