Said tinkering is pretty simple actually, just install weston. Weston is a reference wayland implementation that can run inside X11, so you can run waydroid inside weston
I actually recommend using Niri lately. It’s not super great, but it does support multi-touch, which is major.
I hope cosmic supports it at some point because cosmic actually supports operating in kiosk mode, and also uses smithay.
Just to be sure, you’re talking about this right?
If yes do you mean running using niri instead of weston?
