If you want stable and can deal with the downsides honestly I suggest immutable distros. Otherwise Fedora is pretty reasonably stable for a pretty up to date distro and also has decent community support which is underrated. If your drive(s) are setup for it it’s pretty easy to distro hop anyways so it’s worth a shot

The blade itself is what I’m current reading (when not frantically trying to catchup on one piece)

I’ll probably have to look at the docs but does xrandr assign something like a uuid to displays? I do remember having to set a display manually for one game for Wayland so it launched on the right monitor but I thought I had some issues with the numerical order moving around for some reason. Presumably I’d also want a kvm or something to start the pc from my living room as well and just plug or unplug from the tv itself?
