Starting gnome with kdm?

["Felix E. Klee" <felix.klee@inka.de>]

Hi,

I use Potato with the latest kde 2.1 packages. When I use gdm as a
display manager I can have the option to start kde or gnome or twm.
However, when I use kdm I only have the option to start kde or twm or
sawfish. How can I tell kdm to offer me gnome as an option?

TIA,

Felix
