Is there a better mailing list to use to ask questions like this?

I can't find a mutter mailing list, does one exist?

Meanwhile I've managed to get as far as:

$ gnome-shell --wayland
..
gnome-shell:22377): mutter WARNING: Can't initialize KMS backend: Could not get session ID: No such file or directory.

Is there an equivalent to "weston-launch" for gnome-shell?
