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.

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

the physical display output is claimed by something else totally separate.

Yes, and the above solution I laid out is a way to get around that, that potentially dodges the complexity of configuring a headless session. It's possible to run two KDE sessions at once, next to eachother, and then simply put one on the main display, with the second being "headless", and not shown.

I started fiddling with the above setup I described, actually installing and testing sunshine. Unfortunately I hit some hiccups. I got sunshine to run, but with no input, and then then it attached to the wrong KDE, even though it was streaming the correct one initially. Now I'm running the same KDE session as a different user (since I was on the same user before), but having pairing issues, but I suspect these are because moonlight is seeing the wrong SSL cert, since the sunshine as a new user generated a new cert.
