shell script to start gnome?

[dep <dep linuxandmain com>]

greets!

eschewing xdm/gdm/kdm, i'd like to be able to switch among various 
desktops from a console (not a console emulator, pure command prompt, 
no x running until the desktop is chosen).

is there a gnome shell script that does this, which is to say starts x 
with gnome?

thanks.
