As described in <https://lists.debian.org/debian-devel/2016/08/msg00554.html> I'm trying to reduce how much dbus-launch is used in Debian. xfce4-session has code that explicitly runs dbus-launch if DBUS_SESSION_BUS_ADDRESS isn't set, in two places: * shell code in scripts/xinitrc.in{,.in} * C code in xfce4-session/main.c, which looks as though it might be derived from gnome-session or share a common ancestor The major D-Bus implementations (libdbus, GDBus, sd-bus) now have a fallback code path, before trying X11 autolaunch, when DBUS_SESSION_BUS_ADDRESS is unset: if XDG_RUNTIME_DIR is set, and XDG_RUNTIME_DIR/bus exists, is a socket and is owned by the process's uid, then they will use it. In particular, dbus-user-session sets up that situation. For the moment, dbus-user-session does make sure DBUS_SESSION_BUS_ADDRESS is set, to be nice to packages that don't have this fallback path. However, I'd like to avoid requiring that in future, by adapting the dbus-launch code in gnome-session and similar session-starters to look for XDG_RUNTIME_DIR/bus before trying dbus-launch. I'll open an upstream bug for gnome-session after doing this MBF. A similar solution will probably be applicable to xfce4-session.
