Paul, do you have any specific card recommendations? I see Eyefinity
listed on everything from cheap desktop class cards to massively
expensive workstation cards.

I would hesitate to be quite so harsh on ATI graphics on Linux. I do agree
that the drivers are less friendly than the nVidia drivers, but as long as
you're using the binary blob drivers from AMD's website, they do work well.
And the Catalyst Control Center has been ported to Linux and is included with
the binary drivers, which makes setting up multi-head (even massive 6-display
Eyefinity setups) trivially easy.

Howdy All -
I currently use a dual-head setup using a relatively inexpensive
nVidia Corporation G73 [GeForce 7300 GT] card. I use the DVI and the
VGA cables at the same time, and it works just fine. I can do wobbly
windows and spinny desktops and all that jazz (yeah, I like the eye
candy, sue me).
I want to go to triple head. I am reasonably sure I can do it with
e.g. an NVidia Quadro NVS 450, but I am curious as to whether the
driver will do accelerated X? Three monitors will be nice, but not if
I lose capabilities I have now with dual.
So... anyone got any experience with triple-head or beyond? Any advice
on NVidia Quadro vs. maybe ATI's offering?
I'd love to hear any stories - good or bad - about accelerated X on
more than two monitors.
I wouldn't use anything but NVidia with Linux. Open source zealots complain
that the NVidia drivers aren't open source, but who cares?
NVidia gives them away for free, and they've been extremely supportive of Linux
since day one. I used to support high-end 3D scientific visualization Linux
workstations, and I always used Nvidia hardware. The performance is awesome,
the driver provides lots of tweaking, and it's incredibly well documented! You
will never go wrong using NVidia on Linux.
I think Intel provides good Linux support for their video cards, but I have no
first hand knowledge.
ATI's support of Linux leaves something to be desired. Some people say the ATI
support is good and open source, but after days of googling, I still couldn't
tell with absolute certainty which driver was the correct one for the ATI chip
I was working with. I recommend avoiding ATI altogether.
As far as whether or not your accelerated effects would work across all the
monitors, the number of monitors your using shouldn't make a difference as long
as the driver/video card you are using supports those 3D affects. If it works
with one, it will work with 2, 3, 4, .... I would not try to mix-and-match
video cards and drivers, however. This shouldn't be an issue with the Quadro
NVS 450, since it's designed to support up to 4 displays from a single card.
