triple-headed X configuration in Fedora using Xorg nv driver
I just finished setting up a functional 3-headed display using Fedora 8
and the nv driver. There seem to be a lot more questions than answers
out there on how to do this, so I thought I would share what I have.
The Monitors: 2 24" displays (left and right) with a centered 22"
display in portrait mode (Great for PDF reading and document editing).
The video cards: 1 GeForce 8400 PCI-E, 1 GeForce 8300 PCI-E, 1 GeForce4
MX 4000 PCI. Relevant portion of lspci:
The GeForce4 is powering the rotated display. Evidently randr rotate
support via nv is only available on models before the NV80, so the PCI
card is necessary for now. Hopefully I can pick up a faster alternative
Drop to 1 or 2 video cards with multiple outputs (Having trouble getting
the driver to handle the displays separately)
Bond some screens with either randr or xinerama so windows can move
Figure out some extra flags to boost performance.
The NV 8300 is in a 4x PCI-E slot, mechanically modified to allow the
16x card to fit.
Attached is the xorg.conf.
