Change GDM login background image on OpenSUSE 11.4

First, let me start off by saying I truly dislike Gnome, and the attitude by the Gnome devs that somehow giving people options is a bad thing.  Why is it that I cannot easily change the background image of the Gnome login screen?  Why do I have to use hacks like this one?  Why do the hacks always have to change?  Anyway, for Gnome 2.32.1 which shipped with OpenSUSE 11.4 the way to change the login background image is like this:

As root:

mv your_new_image.jpg /usr/share/pixmaps/backgrounds/gnome/background-default.jpg

Where your_new_image.jpg  is the image you want to be the new background image.

How to change Gnome login background image.

Update: For OpenSUSE 11.4, see this post.

As root, enter the following into your shell:

gconftool-2 --direct \
  --config-source xml:readwrite:/etc/gconf/gconf.xml.defaults \
  --type string \
  --set /desktop/gnome/background/picture_filename some_picture_filename.png

Of course you will need to change the bit in red, "some_picture_filename.png" to the one that you want as your background image on the login screen.

It seems that the method for doing this has been evolving.  What worked even six months ago does not appear to work now.  As of this writing, I am using Gnome 2.30.0 with OpenSUSE.  I found the information here.
