[gdm-list] Dual Monitor and GDM login location

["badstuff9 msn com" <badstuff9 msn com>]

(Noob alert!) 

I am running Ubuntu 9.10 (if that matters). 

I have two monitors attached to the computer. 

When the computer starts up, and then the login screen appears, it 
always appears on our "secondary" monitor.  We would like it to appear 
on our "main" monitor. 

How do I control on which monitor the login screen appears? 

(Sorry - I'm going to need simple-to-understand 
explanations/instructions.) 

Thanks in advance for any help.
