Dear colleagues:
we would like to thank Carsten Schubert, Karin Fritz-Wolf and Oliver
Einsle for reaching out to help us with our configuration of CRT/LCD dual
monitors using an Nvidia FX3500 under RHEL4. We have now been able to come up
with a Xinerama-based configuration that works really well. Our configuration
provides an extended Desktop between the two monitors (the CRT is the login
console) on which we can drag windows back and forth without compromising
stereo-capability/quality. Working with two screens is admittedly quite nice!
I attach an annotated version of our xorg.conf in which I provide information
and comments via a header and via additional remarks here and there, hoping
that fellow-novices in dual-monitor configuration will find it useful.
Best wishes
Savvas

# /etc/X11/xorg.conf for a dual monitor setup (CRT + LCD)
# based on the Nvidia Quadro FX3500 graphics card under RHEL4 x86_64.
# The CRT monitor is configured for stereo applications and should be defined
as "Screen 0".
# It should also be connected to the port next to the 3-pin connection for the
stereo-emitter.
# This is a 'Xinerama'-based configuration which allows one to drag
window-applications across
# the two monitors, without compromising stereo-capability/quality.
# The CRT monitor is the 'mother monitor' and the LCD monitor serves as an
# extension of the Desktop.
