Has anyone gotten three heads set up with Fedora? I
figure it will
require the proprietary driver, and while that is
not optimal, I'm
willing to do it. I really want to have three
monitors set up.

If so, how'd you do it?

I installed Fedora 14 with just the VGA on-board video
running first, then plugged the others in after install...
and everything just worked on reboot. The only adjustment
needed was to place the screens in relation to one another
so that the layout made sense.

I have a pair of NVidia cards (one PCIe, one PCI) which I do this
with. The key components were:

* Proprietary NVidia driver with TwinView enabled
* Specifying the PCI ID manually in my xorg.conf

What I lack is the ability to merge together the Dual-screen config on
one card with the single screen on the other - so in actual fact I
have 2 Xorg "Displays" and am unable to move windows from one to the
other. That's not a big deal - you just end up adapting your workflow
and keeping discrete apps on that one screen. If I enable Xinerama,
Gnome crashes pretty hard on login.

I have included my Xorg.conf below to give you some starting point. If
you get Xinerama working, I'll be very interested.
