Wayland headless multi seat? (sh.itjust.works)

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

Sunshine has some documentation gaps that are annoying to figure out but there enough there you can get it done with some effort. Moonlight feels really crunchy though. Edges are rough and it always felt unfinished. I really think selkies v2 is going to kill it.

Sunshine+moonlight is better for an app based deployment, like set top boxes without web browsers. But if you have a browser available on the client, I can see some crazy possibilities with selkies.

Gamesonwhales solves the sunshine multi user issue in a different way. It’s better for renting out your box as a node for cloud gaming. It’s damn near turnkey for that and super clever. But that’s not what I’m trying to do here so it’s just adding complexity.

From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.
