Of course you will have to modify it but that will help you to see how ti works

Solution 2
Currently, there is no way to make it work so that you are actually using a single session on all three. There is work being done on kernel & Xorg upstream to make it possible, though. It'll still take quite some time to get it in shape, and included in a release.
EDIT: meh, forgot about xinerama, see for instance Triple-head on a Lenovo T520 for instructions about setting it up. Note that you won't get 3D on the intel though, if you use nvidia's driver.

Dom over 12 yearsreally? Can you supply details on this? I find it hard to believe that it's impossible to do 4+ monitors (on session) in Linux. What's preventing it in this case?

Alex about 11 yearsIn this configuration, all seems to be nvidia cards - so is this really the same? Can the X server load two different drivers?
