using another WM alongside gnome

[Dan Davison <davison@uchicago.edu>]

Hi,

I've just installed Debian Sarge on a new laptop. During the install 
process, I chose to have a desktop environment. However I would really 
like to have the choice to quit out of gnome (or never enter it) and use a 
different window manager, when I want. I have the .xsession file from my 
old debian system that sets up an X session with the ion window manager, 
and I would like to be able to choose between using gnome and using ion.

Could someone advise me how to do this? The machine boots directly into 
gnome using gdm, and I have not worked out how to have any control over 
this.

Thanks a lot,

Dan
