How do I disable desktop icons for “Computer,” “Home,” and “Trash?”
If you do not want your desktop cluttered with the default icons for “Computer,” “Home,” and “Trash,” you can disable any or all of them. To do this, launch Applications > System Tools > Configuration Editor (gconf-editor from the command line), and go to the /apps/nautilus/desktop key.
From here, you can enable or disable the icons, and even rename “Home” and “Trash.”
