I am looking into doing a 10 screen installation using Pd/Gem. I'd
like to run it on as few computers as possible. Anyone have any
recommendations for Debian or Ubuntu setups that can have like many
DVI ports in one computer?

hello,
with things like doublehead2go, or triplehead2go : http://www.matrox.com/graphics/fr/products/gxm/th2go/ you can easily have lot's of screen on 1 computer. (downside is that the screen are only horizontal)
i made a 6 screen installation with a 400€ desktop having good performance. (GPU was a NVIDIA 9600 or something : only use nvidia gpu on linux if you need good performance and are not afraid of proprietary driver).
but what is the resolution of the screen? to have a screen disposition like this : x x x x x x is less a problem than like this : x x x x x x The size of openGL windows is hardware limited. usually 4096x4096, but can go up to 8192x8192 with GPU having lot's of memory (go for 1go video Ram).

The screens we are currently specing are 1080p, so each output should
be able to do 1080. The idea is to have 10 contiguous screens all in
a line show one Gem space. They can show up on the computer as
contiguous or separate screens, that doesn't matter, I can handle the
difference in Gem. I think it might be easier to have them show up as
separate screens.
I can break it up across multiple computers if that's easier, I'm
mostly trying to reduce the expense. I am just showing images, so not
heavy on the CPU/GPU.

if you can't place more than 2 or 3 horizontally, you can split it in software. e.g. one box can show a frame with (2*1920) columns and (3*1080) rows, where 3 is the number of horizontal strips, each strip being made for a pair of monitors.

We run a 12-screen video wall in our data visualization research lab – the OpenGL integration has not be without...ahem....bumps, but for the stuff you are doing, if you can invest in the following (we have been running Debian and Ubuntu):
ATI Radeon™ HD 5870 Eyefinity 6 http://www.amd.com/us/products/desktop/graphics/ati-radeon-hd-5000/hd-5870-e...
or
ATI Radeon™ HD 5970 Eyefinity 12 http://www.amd.com/us/products/desktop/graphics/ati-radeon-hd-5000/hd-5970/P...
These are 6-port or 12-port cards. Price point for 12-port is about $750 and 6-port is $500 - $550. They have Windows and Linux drivers. You DO need your displays to have DisplayPort as one of their interfaces. The Dell 3008WFP has this but depending on what displays you may already have, you might need to go with another vendor solution like Nvidia. They have multi-port cards as well.

Ten separate screens or 10 contiguous? I have had problems with more than three with an NVIDIA quadroplex in my work machine. The nvidia quadroplex driver just does not work for me in ubuntu. I would be interested to see what you find out.
I have an winxp/ubuntu dual boot for one theatre and it has 8 DVI outputs, which looks gorgeous with GEM on WINXP [7000x1050]

Hi Hans,
We've been used in mobilecrash installation (4 dvi outputs) an asus
motherboard with 2 nvidia cards pci-expr (9800 gs), in sli mode, under
ubuntu 9.1.
Now we will start some tests using 6 heads in one pc, but using an
analog matrox triplhead2go.
But I would like to hear more about this subject also.

I've done 2x Nvidia cards for 4 DVI screens, could possibly add more, but often it's cheaper or easier to use a network of cheaper computers that can run 1 or 2 screens with media locally stored, esp if the projectors or screens are not at the one location. Ethernet is much cheaper and easier to run than DVI links.

the biggest thing i did with something like this was an 8 projector installation [1], using a single computer (running ubuntu; i would have preferred debian, but some software we had to license was only available for ubuntu)) with 2 "recent" nVidia cards (forgot which ones; it was done last year, so probably it was 2 GTX295 or similar); 3 heads where equipped with triplehead2go, which would have made for a total of 9 projectors, but we only needed 8; the remaining head was the control computer to do the patching.
there were 2 problems involved (and solved):
we ended up solving by forcing EDIDs)
depending on your hardware/driver combination, you get a maximum texture size. with the cards we used this texture size was 8192x8192. this size (both horizontal and vertical) is an upper boundary for hardware-accelerated window sizes. so you cannot do a line of 8 projectors in a row, each with a resolution of 1080p, as this would sum up to a window of (8*1920)x1080==15360x1920, and 15360 clearly being >8192. what you can do is to have your line of 8 screens form a virtual monitor of 4x2 screens, covered by a 7680x2160 window and use framebuffers for rendering the scene (this really only matters if there is continuation between the screens (e.g. in our project we actually had one huge 270° screen, which was fed by 8 projectors) if the screens are more or less independent, then it's way simpler)

- getting the gfx-card recognize the 3head2go over shitty cables (which

using good cable is also a good way to avoid problem...

i think the easiest would be to use 2 gem windows of 7680x1080, and render exactly the same scenne in both. just having to change the perspective of the openGL windows in order to have a perfect continuity...

well, since one running instance of Pd/Gem can only create a single Gem window, i think it is easier to create a single gem window of 7680x2160, use 2 framebuffers of 7680x1080, render the scene twice using perspective and whatnot and then display the 2 framebuffers in the single window.

yes, you are right. i think last time i did this, the framebuffer where not available... c
