+## xwayland script
+I currently use Emacs remotely for my work (because the emacs lsp glue code doesn't currently support tramp) and
+I've found that, even though this is not an ideal setup, running X inside of `gnome-shell -nested` inside of the
+X on the desktop actually does work. So, until we can run Wayland on the Steam Deck desktop and that language
+server code works within tramp, this is what I'll be using for my work. Aaaand, it's a full-screen window for
+now, until I can get rootless working.
+
+This runs the `awesome` window manager which, just to make things even more indirect, I have installed inside an
+Ubuntu distrobox so I can avoid dirtying the Steam Deck's root any more than I need to. So I run xwayland in
+distrobox. When you quit `awesome`, it kills xwayland for you.
+
+So feel free to use this but you have been warned...

+#!/bin/sh
+Xwayland :3 -fullscreen -geometry 1920x1080&
+#Xwayland :3 -fullscreen -geometry 3840x1080&
+pid=$!
+sleep 2
+echo PID=$pid
+export DISPLAY=:3
+awesome
+kill -2 $pid
