cage

Anything special about Raspberry Pi's that require X11? Raspberry Pi OS defaults to Wayland nowadays, and there's specific kiosk Wayland compositors like Cage (https://github.com/cage-kiosk/cage). Tho admittedly kiosk-wm (https://github.com/JOT85/kiosk-wm) is much more succinct.

Oh, it's like cage ( https://github.com/cage-kiosk/cage ) for X11. I was wondering ex. how you'd even move windows around in that little code; the answer is "you don't":)

> but worst case I'll run a Wayland compositor on my X11 server for that This is actually surprisingly easy, too. My first experiments ran a wayland app in cage ( https://github.com/cage-kiosk/cage ), but in order to better handle multiple windows I switched to sway with a lightly tweaked config, and other than some input weirdness (I think it struggles with modifiers held while switching focus) it works pretty well.

I haven't personally used it, but I have seen cage [0] being recommended a few times for similar use-cases. [0] - https://github.com/cage-kiosk/cage

You... might be able to, kind of, depending on your goal... So the thing is, if all you need is a single screen (or at least, I've not run this multi-monitor) and you're just working around drivers that don't support Xorg, you can just run cage ( https://github.com/cage-kiosk/cage ), run xwayland on that, and run your real GUI on that. Of course, then you're skipping all the advantages of wayland except hardware/driver compatibility. For "real" wayland, sibling comments are correct that you'd need a wayland compositor that reimplemented awesome.

If you want to avoid having switch back and forth, you might try running things inside a wayland compositor under X11; for example, when I want to run waydroid I just run it in cage[0] in a window in my usual environment. [0] https://github.com/cage-kiosk/cage

That did help me find https://github.com/cage-kiosk/cage/wiki initially I'm here there's other going down that path. Thanks

You probably know about it, but in case you don't know: You can run Wayland inside Xorg via cage[1] so you don't need to use a Wayland compositor. [1]: https://github.com/cage-kiosk/cage

The simplest thing I know of is the minimal Cage compositor for wayland, that only supports running a single fullscreen program: https://github.com/Hjdskes/cage With some hackery, you could probably build this as a backend for GTK/Qt that would run the server in the same process. But I don't know how useful that would really be.

It IS being worked on but in the meantime, gio apps can be run on X using https://github.com/Hjdskes/cage (a very simple wayland compositor)
