Default Triple Monitor Setup Trouble in Debian Lenny

I would like to set up a triple monitor system, in which there is one desktop environment distributed across all three monitors. I read (somewhere) on this website a while ago, that it is possible to implement, but I would need a minimum of two video cards each of which make use different graphics processors. I have a GeForce 7600 that does dual, fully digital monitors perfectly well at the 1920x1200 resolution native to those monitors. I have recently acquired a GT240 for the third monitor, as it uses a different graphic processor than the first card and provides the necessary output connector types. Clearly both are nVidia. I have not been able to get any output from of the second card regardless of how I configure the system in the xorg.conf file.



Question: How must the system (drivers, etc . . .) be setup for both video cards to be active in the manner described above?

OS: Debian Linux 5.0.3
Processor: Core 2 Duo 2.8 GHz processor with 4 GB RAM


Thank you in advance for your assistance.

Hi!

Can you please post an nvidia-bug-report.log? Otherwise it's pure
speculation what's in your xorg.conf and what might have gone wrong.

Anyway, when mixing GPUs of different families, then 3D will only
work with one of the two GPUs.

regards

I am not certain that there is a bug report. My objective is not a 3D monitor setup, but rather a triple monitor setup. This is to say that I desire to have three monitors hooked up to one motherboard, at the same time. I have two of the three working, but I have yet to figure out how to activate the second video card, which drives the third monitor.

Are there utilities available that allow me to determine if the system even sees the second video card?

Thanks for you help in advance.

Sorry for the confusion - please type "sudo nvidia-bug-report.sh" and post the
resulting "nvidia-bug-report.log.gz". This file will give the forum members insights
of your hardware/software setup and potentially gives hints of what is going wrong.

I understood that part and just wanted to point out that you won't be able
to run OpenGL applications ("3D") across all three LCDs when mixing
GPUs of different families.

BTW.: I recommend reading posting #2 of the following thread
to learn more about the pros and cons of multi-GPU setups:
