It’s a little hard to decipher what you mean. I think I understood that you basically want to have a headless gaming rig so you can stream your games in the rest of your network. The closest you would get is probably Bazzite, and configure it to directly boot into steam big picture mode so you can use steam link on your connecting devices. If you would like a platform agnostic setup you could look into sunshine. That will involve more tinkering tho.

I tried working with tiling and while it felt kinda cool, in the end it didn’t solve any problem I have. At most I’m working in 2 different windows 99% of the time and I have a second monitor for that. So it’s not that hiding windows is a use case, it’s that tiling them isn’t one.
