I’m currently working on a project to make a touch screen home dashboard and entertainment device. I’m done making its player software, with MPV in the backend, and my next step is to make an Electron overlay dashboard and launcher.
Essentially, I’m looking for a kiosk-style window manager (or something that lets me auto-login and turn off window switching), that would support a transparent overlay application always on top (my Electron dashboard and launcher) over whatever app is being currently used, be it MPV playing a video, or even Steam playing some games. I’m alright with Wayland or X, whichever would have the features I need and would be the most performant!
This is my first deep dive into Linux Window Managers, so if I’m completely off base here, I would might need help to clarify things as well. Thanks in advance!
You might want to take a look at cage which has been designed for that.
I was looking at Cage yesterday, but it seems like it wouldn’t support a transparent always on top application, in a way to give control to any application underneath. Maybe I could experiment with it and see what I can do…
