Don’t believe me? Prashanth Ellina tells you how!

Here are the instructions available on his website:

To stop Nautilus for drawing the desktop by default:
gconftool-2 --type bool --set /apps/nautilus/preferences/show_desktop false
Get the xscreensaver (matrix in this case) to draw itself on the desktop
/usr/lib/xscreensaver/glmatrix -root
You can also get the animation working everytime u log in by typing the following instructions:
vi ~/.config/autostart/glmatrix.desktop - use your favorite text editor to open the file
[Desktop Entry]
Version=1.0
Encoding=UTF-8
Name=No name
Name[en_IN]=Desktop matrix
Exec=/usr/lib/xscreensaver/glmatrix -root
X-GNOME-Autostart-enabled=true
If you want to revert to your old desktop setting:
gconftool-2 --type bool --set /apps/nautilus/preferences/show_desktop true && nautilus
Awesome Tip! Major Thanks to Prashanth for putting up the original article
