Stopping GNOME Launching on Reboot

["Roland Dunn" <roland@dunn.co.uk>]

Hi,

Having typed: "update-alternatives --config x-session-manager" and
choosen GNOME, GNOME now starts up on reboot. I'd like it not to so that
I can type "startx" when I want it to go into GNOME. How can I force it
not to launch GNOME on reboot?

Cheers Roland.
