O.k. I think now I get the full picture, thanks for the detailed 
explanation :-)

In one of my computers (running lenny and gnome) I have 2 displays in a 
top/bottom layout (one display is on the top of the other).

I use nvidia card with dual DVI-D ouput and a I have chosen a "separate 
display" layout, so in one display (the bottom one) I get the full 
desktop icons and bottom bar but the display on top is just clean (no 
bars neither icons, just the background).

I am using nvidia propietary driver which allows to select that "mode" 
under /etc/xorg.conf named "twinview". So I guess you will have to dig a 
bit about your card (and driver) capabilities and specify the desired 
mode in your xorg.conf file.

What VGA(s) do you have in that machine and what driver is being used?
