"Debugging mutter
You can debug mutter (used in gnome-shell) by setting its environment
variables. These need to be set prior to run gnome-shell, so if you
want to log into GNOME from GDM, you need to create a wrapper script
called from a desktop file in /usr/share/wayland-sessions.
FIXME: Putting the wrapper script and desktop file here would be helpful."
Any chance anyone with time and interest to fix the fixme here?
