    ibusManager: Ensure to spawn --xim on non-wayland sessions
    
    This (mistakenly) now only depends on signals triggered on Wayland
    sessions. Hardcoding the XIM support on X11 sessions will make input
    in some clients work again.
    
    Closes: https://gitlab.gnome.org/GNOME/gnome-shell/issues/1690
