Hi,

I'm trying to run some dbus-send commands as an unprivileged user (which I called "myremote"), but none of them work.

the same commands, if issued by "root" or "user", work perfectly.

for example, I can run as root this command:

Code:

dbus-send --type=method_call --dest=com.nokia.profiled /com/nokia/profiled com.nokia.profiled.set_profile string:"silent"

and put the phone to silent mode.

however, if trying to run it as "myremote", i get the following:

Code:

Failed to open connection to "session" message bus: (null)

i've read from here that I could try the following

Code:

eval $(dbus-launch --sh-syntax)
export DBUS_SESSION_BUS_ADDRESS
export DBUS_SESSION_BUS_PID
run-standalone.sh dbus-send <etc. etc. command here>

but still no result.

any hints?

Second paragraph here: http://www.freedesktop.org/wiki/Software/dbus

There is one session dbus and one system dbus. Your error message states that you failed to get to talk to a session dbus. You need to talk to the system dbus.

Thank you for your reply.

Ok, so I think adding "--system" should do it (or should have done it).

I came out with the following, but I still have an error and no effect

Code:

run-standalone.sh dbus-send --system  --print-reply --dest=com.nokia.mafw.renderer.Mafw-Gst-Renderer-Plugin.gstrenderer /com/nokia/mafw/renderer/gstrenderer com.nokia.mafw.renderer.next
Error org.freedesktop.DBus.Error.ServiceUnknown: The name com.nokia.mafw.renderer.Mafw-Gst-Renderer-Plugin.gstrenderer was not provided by any .service files

I tried also the "eval $(dbus-launch --sh-syntax) etc." part, with no luck.

Also, I'm not sure I need to talk to the system dbus: the same command run as root requires --session, it won't work with --system!
