Hi Rob.

What desktop GUI are these machines using?

Is there some way you get each machine to use it's own 
custom xorg.conf file, that you can tweak for each 
particular machine?

I use this this in my PC running Centos 5.8 32 bit,
and XFCE desktop, to give me a tall virtual screen that I 
can scroll around vertically:

# Xorg configuration created by system-config-display

Section "ServerLayout"
         Identifier     "single head configuration"
         Screen      0  "Screen0" 0 0
         InputDevice    "Keyboard0" "CoreKeyboard"
EndSection

Section "InputDevice"
         Identifier  "Keyboard0"
         Driver      "kbd"
         Option      "XkbModel" "pc105"
         Option      "XkbLayout" "gb"
EndSection

Section "Monitor"
         Identifier   "Monitor0"
         ModelName    "Monitor 1024x768"
         HorizSync    31.5 - 61.0
         VertRefresh  50.0 - 75.0
         Option      "dpms"
EndSection

Section "Device"
         Identifier  "Videocard0"
         Driver      "nv"
EndSection

Section "Screen"
         Identifier "Screen0"
         Device     "Videocard0"
         Monitor    "Monitor0"
         DefaultDepth     24
         SubSection "Display"
                 Viewport   0 0
                 Virtual   800 1800
                 Depth     24
         EndSubSection
EndSection

Kind Regards,

Keith
