Start Gnome in FreeBSD 4.5

I was finally able to get FreeBSD working with X-windows and KDE. I installed Gnome also. However am not given the chance to run Gnome when I type: startx at the command line. KDE seems to be default
How can I run Gnome too?

Redhat has a tool called "switchdesk", I think that might be RH specific though. Check out your ~/.xinitrc files or see "man startx". xinit controls the programs that start when you launch X.
