I'm running Ubuntu 8.04. It was a default Desktop install type, so it is running gdm. Oh, and the theme is "Human".

Is there a way to disable the F10 key at the login screen? If I hit F10 I get a menu of items such as "Select language...", "Select session...".

This machine is being setup as a public computer and I wish to disable this menu altogether. I've tried setting SystemMenu=false in gdm.conf-custom but that only removed some of the menu items from F10.
