Setting DISPLAY should allow that I think. If I launch qdbus on an ssh session to localhost, I get this Could not connect to D-Bus server: org.freedesktop.DBus.Error.NotSupported: Unable to autolaunch a dbus-daemon without a $DISPLAY for X11 If I set DISPLAY=:0 and run qdbus again, it correctly lists the registered connections on my session's bus. @David: just to see if it would work with the actual bus address being available: - in your main session, get the value of $DBUS_SESSION_BUS_ADDRESS - in your ssh session, set that variable to that value and try qdbus again Cheers, Kevin -- Kevin Krammer, KDE developer, xdg-utils developer KDE user support, developer mentoring
