desktop icons in gnome

[Ed Kademan <ejkademan@yahoo.com>]

I would like to get rid of the trash, computer, and home icons on my gnome
desktop.  I tried

gconftool-2 --set --type=bool /apps/nautilus/desktop/trash_icon_visible false
gconftool-2 --set --type=bool /apps/nautilus/desktop/computer_icon_visible false
gconftool-2 --set --type=bool /apps/nautilus/desktop/home_icon_visible false
gconftool-2 --set --type=bool /apps/nautilus/preferences/show_desktop false

but this didn't work.  I would appreciate any suggestions.  Thanks for your time.
