This error message is printed into the journal if a GTK app can't connect to eithre Wayland or X11. Make it at least mention who is not capable of connecting to a server. Unrelated, we might want to improve our error reporting when a GTK app can't start, so that debugging issues with system startup / login get easier to resolve.
