Almost certainly. The dbus-daemon is started on a per-greeter basis (one per X11 or Wayland display) because on multi-seat or XDMCP systems, gdm wants to run several independent sessions all sharing one uid; so it can't talk to `systemd --user`. The error message is different because gsd-sharing is still trying to perform activation via autostarting, whereas gnome-session has been taught not to try to do that (it won't work). Ideally these messages shouldn't appear, but I don't think they indicate a real bug. > comm="/usr/libexec/gsd-sharing " In an ideal world, I suspect this service shouldn't even be started in the greeter: there's no reason why the greeter session would want to share anything with a LAN. smcv
