Setting up XFree86 ver 4.x.x server for dual server for multiple 
resolutions on RedHat Linux 7.x -John Stokes, Unidata

 
First we need to make resolution changes in our config file:  
/etc/X11/XF86Config-4

We start with a "Screen" section that resembles:

>>>>
Section "Screen"
        Identifier "Screen0"  
        Device "ATI Mach64"
        Monitor "Korea Data Systems Visual Sensation VS-21"
        Subsection "Display"
                Depth 24
                Modes "1280x1024"
        EndSubSection
EndSection
<<<<

We want to add another "Display" section with a low res depth.  This will
look like: 


>>>>
Section "Screen"
        Identifier "Screen0"  
        Device "ATI Mach64"
        Monitor "Korea Data Systems Visual Sensation VS-21"
        DefaultDepth 24
        Subsection "Display"
                Depth 8
                Modes "1280x1024"
        EndSubSection
        Subsection "Display"
                Depth 24
                Modes "1280x1024"
        EndSubSection
EndSection
<<<<

(note we added a 'DefaultDepth 24' line. This is what our default server
starts up as.)

Next we should make sure that we are running our default server on virtual 
terminal 7 (ctrl-alt-F7). The bottom of the gdm config file 
/etc/X11/gdm/gdm.conf should look like:

>>>>

[servers]
0=/usr/bin/X11/X -depth 24 vt7
#1=/usr/bin/X11/X -depth 8 vt8

<<<<

Finally, a script that invokes a new X server, sets the DISPLAY variable, 
starts a simple window manager, and then loads ntl should do the trick. 
Restart the X server and you are ready to go.

This script is what we use locally:

>>>>


#!/bin/csh -f

setenv DISPLAY :0

X :2 -depth 8 -ac vt8 &

setenv DISPLAY :2

twm &


source /home/gempak/Gemenviron

ntl &

#xterm &
