Let root query screensaver status for user

Hmmm... weird. It works for me with --session
[krzysztof.konopko at some-pc]$ su -
[root at some-pc ~]# sudo -u krzysztof.konopko dbus-send --session \
--dest=org.gnome.ScreenSaver --type=method_call --print-reply \
method return sender=:1.58 -> dest=:1.240 reply_serial=2
It doesn't work with --address though.
Are you sure that user 'joe' is logged in?
Is there any specific entry for the root user (or any group that root
belongs to) in your /etc/sudoers?
