Instead of passing ---auto-syntax, you may explicity specify a particular one by using ---sh-syntax for Bourne syntax, or --csh-syntax for csh syntax. -In scripts, it's more robust to avoid --auto-syntax and you hopefully -know which shell your script is written in.</para> - - -<para>See <ulink url='http://www.freedesktop.org/software/dbus/'>http://www.freedesktop.org/software/dbus/</ulink> for more information -about D-Bus.

This can be suboptimal or even totally broken, depending -on the app and what it tries to do.</para> - - -<para>There are two common reasons for autolaunch. One is ssh to a remote -machine. The ideal fix for that would be forwarding of -DBUS_SESSION_BUS_ADDRESS in the same way that DISPLAY is forwarded. -In the meantime, you can edit the session.conf config file to -have your session bus listen on TCP, and manually set -DBUS_SESSION_BUS_ADDRESS, if you like.</para> - - -<para>The second common reason for autolaunch is an su to another user, and -display of X applications running as the second user on the display -belonging to the first user. Perhaps the ideal fix in this case -would be to allow the second user to connect to the session bus of the -first user, just as they can connect to the first user's display. -However, a mechanism for that has not been coded.</para> - - -<para>You can always avoid autolaunch by manually setting -DBUS_SESSION_BUS_ADDRESS. Autolaunch happens because the default -address if none is set is "autolaunch:", so if any other address is -set there will be no autolaunch. You can however include autolaunch in -an explicit session bus address as a fallback, for example -DBUS_SESSION_BUS_ADDRESS="something:,autolaunch:" - in that case if -the first address doesn't work, processes will autolaunch.
