Completely hide top panel in Ubuntu

After struggling with this for a little bit, and not finding any satisfactory solutions online, I was able to come up with this. Save the following script and add it to your startup applications:

#!/bin/bash

gconftool-2 --type List --list-type String \

--set /apps/panel/general/toplevel_id_list "[]"

Note: This will hide all your panels. I’ve only tried this in Ubuntu 10.04 (Lucid).
