DBUS_ENABLE_X11_AUTOLAUNCH obviously requires DBUS_BUILD_X11. However, the converse is not true. If DBUS_BUILD_X11 is defined, dbus-launch will be able to connect to the X server to determine when the session ends; most distributors will want this, but it can be disabled with the standard Autoconf option --without-x. If DBUS_ENABLE_X11_AUTOLAUNCH is *also* defined, dbus-launch and libdbus will be willing to perform autolaunch. Again, most distributors will want this, but it can be disabled with --disable-x11-autolaunch. Bug: https://bugs.freedesktop.org/show_bug.cgi?id=19997 Reviewed-by: Colin Walters <walters@verbum.org>
