Hah, I thought about that, matrox and
their old crappy pci cards with many display ports. They never
supported linux for anything, nor did anything 3d to save their
life with any performance, even under windoze xp, so I don't
expect they'd like any sort of modern compositor which any linux
is hell-bent to insist on.
I was eyeing the nvs line, as those kept turning up under ebay
searches for quadro's at a not insane price, but seems for mosaic
mode you need keplers, most only had 3-4 ports on each, which is
what amd's eyefiniti feature does. I can get asus amd cards with
6 ports still, without the insane "workstation" price, if only
their drivers didn't suck so much. I think even amd gave up on
selling overpriced firegl cards, but somehow nvidia still thinks
the world is their oyster.
If I weren't so spoiled by devices of my own creation, I'd
probably just back to 2-3 displays for stability, but I enjoy the
stereo vision of wrap-around monitors, even if it does bring out
my ADHD.

I think their consumer cards and quadros are limited
to 2 displays. And the nvs line is built for 4. Now depending on
what your system has available you could go with 3 cheaper
desktop cards and run them that way. Makes me wonder if Matrox
is still around doing their thing or not.

Interesting note (imho), I went digging around nvidia's
site today, trying to familiarize myself with their line
of overpriced video cards aka quadro's. What I found was
most of their website doesn't render or work properly,
half the links were broken, half their pdf's didn't
download, and in general looks like something a 10 year
old put together (or me, meh for aesthetics). Wow, you'd
think they could afford some competent web developers at
least.
Sadly seems every card that can do "mosaic" mode,
including sli to achieve nvidia's qualifications to
support sli were $500+ used on ebay, needing multiple
cards of them, in the kepler (K) line of cards or better
to achieve. I guess it's one of those ymmv/"get what you
pay for" sort of things to support what I don't
necessarily expect should cost me $1000+ to support my 6
displays, and really not sure even that is any
better/worse than AMD's support until I see it.
Seeing as no one at AMD gives a real darn about real linux
support (hark! yet another COD windoze game came out with
broken dx rendering, support!), it might be worth the
price, but the childish/broken website from nvidia makes
me loathe to want to invest there either, figuring I'll
see the same brokenness I see with amd.

Stephen, out of curiosity, what does your
xrandr show as a max framebuffer size on your
quadro?
mb@host:~$ xrandr | grep maximum
Screen 0: minimum 320 x 200, current 11520 x 1200,
maximum 16384 x 16384
This was a big limiter for me, in the past I
couldn't figure out why my old ATI 5800 card with
6 ports wouldn't support a full, single
framebuffer, but was internally limited to
8192x8192, with the 6xxx+ supporting 16384x16384.
Xorg wasn't too forthcoming with that info, and it
was prior to xrandr support in their drivers, so
totally left me scratching my head until
escalating with AMD support to an engineer with a
clue that told me that.
With the advent of 4k displays, they still seem
limited to that, which means I can only do 4x wide
until vendors give to open that up.
Thanks!

Next time I have an absolute need to upgrade
hardware, I plan on avoiding ati/amd at all
costs. After dealing with them for a good 5
years as the only real viable option to run my
displays, only to be wrought with constant
disappointment, problems, and frustration.
Buying highly overpriced quadro cards might be
money well spent at this point, but I still
despise nvidia that they're really little other
than rebranded, and marked-up normal video cards
with driver-locked (to bios-id) features.
That said, going to set up some ebay agents to
look for decent quadro's to snipe. I had good
luck getting my last few amd cards that way on
the cheap, gotta love jbidwatcher for cheating
some other person with a last-second bid.
Thanks as always for the input Stephen.

I
have almost given up on ATI, if i want just
multiple screens i would look into the
Quadro NVS cards. Such as the NVS 510 or the
K1200. They may be very proprietary to get
running, but my success with Nvidia cards in
both linux and windows really makes it
worthwhile. These cards will only do a
single monitor, but they are cheap enough to
run 2 cards with reasonable usability. or
one NVS and one more Gamer friendly card.
