gconftool-2: change background image from ssh

[Germana Oliveira <germanaoliveirab gmail com>]

Hi!

The thing is i wanto to:

- connect to a remote host(s) in a lan

- change the background image without restart the computer

- block this option, so the user can not change it

So, until now i can:

- block the user and

- change background AFTER restart

Using:

gconftool-2 --direct --config-source xml:readwrite:/etc/gconf/gconf.xml.mandatory --type string --set /desktop/gnome/background/picture_filename /usr/share/backgrounds/image

the thing is i don't want to wait until user restart the computer to background change take efect.

Is there a way i can do that with root?

Thanks!!!
