[gdm-list] Two Displays Problem

["Thomas H. George" <lists tomgeorge info>]

My system is Debian Lenny with an Ubuntu chroot.  To use the Ubuntu 
chroot I must stop the Lenny gdm and vice versa.
I have tried editing gdm.conf for each system and inserting in [daemon] 
a line FirstVT=7 for Lenny and FirstVT=9 for Ubuntu plus 
VTAllocation=true  for both.  I have also inserted in [servers] a line 
0=standard for Lenny and 1=standard for Ubuntu.


None of these changes solves the problem although they do ensure that 
the Lenny window is at F7 and the Ubuntu window is at F9.  (F8 is a 
console for Ubuntu and this works fine thus allowing me to edit gdm.conf 
for Ubuntu.)

Is there a solution to my problem and, if so, what am I doing wrong?
