I haven’t really done anything with passing parameters to dbus-send etc. but a couple of things spring to mind.

Firstly would using the system bus work rather than the session bus :-

dbus-send --system --type etc etc.

Or failing that can you find out the name of the user logged in and use the su -c command as root to send the info as that user? (Not ideal but might work):-

LOGUSER=[ some code to work out the user ]
su - $LOGUSER -c dbus-send –system –type etc etc


Nice article! I’m trying to grow from it to custom my acpi power button event to ask user to shutdown when button pressed. But I can’t handle the fact that root can’t send message to other users.I’m using

#usr/bin/dbus-send –session –type=method_call –dest=org.kde.ksmserver /KSMServer org.kde.KSMServerInterface.logout int32:1 int32:2 int32:0

this works fine when called from the user logged in, but not from root.

Do you know how to handle this situation?

Thanks.

I managed to get a desktop shortcut to work. I created it with the following executable command:-

/usr/bin/dbus-send –print-reply –session –dest=org.kde.ksmserver /KSMServer org.kde.KSMServerInterface.saveCurrentSession >/tmp/session.out 2>&1

Not that when this is clicked it creates a file call /tmp/session.out that you can look at to see the output of the command. Also I have added the –print-reply option which will show the response from the dbus server. Which should be something like:-

method return sender=:1.6 -> dest=:1.49 reply_serial=2

Thank you for your useful suggestion on using dbus-send. In my case (Kubuntu 8.04, KDE4) however it didn’t work. I checked with kdbus and found the command line that worked:

dbus-send –session –dest=org.kde.ksmserver /KSMServer org.kde.KSMServerInterface.saveCurrentSession

This allowed me to save the session I needed, though this session included terminal I used to run the commanу itself. When I tried to use ‘run command’ on KDE desktop it didn’t work.

Thanks and regards

I haven’t seen that issue with the 3.5 builds, certainly Hardy Heron 3.5.9 has a save session button on the kicker as long as you have “Restore Manually Saved” session switched on in the Session Manager.

However in KDE 3.5 the dcop equivalent is:-

dcop ksmserver default saveCurrentSession
