I have an xinerama set up with RH7.0, XF86 4.0.3 with three screens driven
by three PCI nVidia GeForceMX2 cards, which works well with as one big
desktop. Here's the configuration file. I hope it can help.

I just finish installing redhat 7.3 and I have a S3 Savage (4 head video
card) using three monitors. After I edited the "XF86Config-4" file I got
Redhat to enable the heads but I can only see the same desktop in all
three monitors. I also have xinerama enable but no luck.
Those anybody know how to have those three screen as one big desktop?
