This message is harmless and unrelated.

Thanks for sending detailed information, it helps a lot. Here is the
problem. You don’t have a session manager installed, so the X11 startup
scripts choose to run x-window-manager.

And here, x-window-manager certainly points to metacity. Which is just a
window manager, not something able to start programs.

There is a reason why gdm depends on a session manager (x-window-manager
being a fallback), and a reason why metacity recommends gnome-session.
