6 Monitors - Ubuntu 8.04 - Compiz Fusion - XGL NVIDIA Working! (Video Included)

[d2globalinc]

So it's a limitation with the technology of dual channel ram then? Mine is running in dual-channel mode, but only clocked at 800mhz.

Same here - if I yank 2 chips I can get the higher speed.

[d2globalinc]

So, I'm looking forward for a solution, yet mailed nvidia if and when they are going to implement multi-card twinview support for the usual GeForce series (Quadro series yet supports it via SLI Mosiac technique). I'm on Ubuntu 8.10 by the way, so far with no problems.

This may be a solution for 3 monitor systems: http://www.matrox.com/graphics/en/su...igital/howto1/

There have been people on the nvidia forums and elsewhere who have gotten it to work well with linux.

I was thinking of trying to dasiy chain a few myself - but havn't got the time to take on that mess of a project right now. It would be nice to push all 3 cards into SLI mode powering a single port then spreading that resolution across 6 monitors.

I played with that earlier, but didn't get it fully working like other guys, there were some problems here and there.

Well I worked on this (with DASPRiD) for a while.

I got everything working under Intrepid. 3 monitors @ 1920x1200 / Compiz / Mouse / Keyboard all that jazz.

However, X crashed 3 times during the couple of hours I was working on it, and since xserver-xgl is not being developed, I don't think this is really an option.

Which absolutely sucks, because this is exactly what I need.

Still, there are worse ways to spend a Saturday afternoon!

Hello,

I need some help, I'm trying to set a 6 monitors configuration using this hardware configuration :

Q9400
P5N-T Deluxe
3x Asus 9800GTX+

I'm using Ubuntu 8.04 Hardy

It seems to be an hardware problem because my third GPU is not recognized by the nvidia driver, when I'm looking at the /var/log/Xorg.0.conf :

(EE) NVIDIA(GPU-2): Failed to initialize the NVIDIA graphics device PCI:7:0:0.
(EE) NVIDIA(GPU-2): Please see the COMMON PROBLEMS section in the README for
(EE) NVIDIA(GPU-2): additional information.
(WW) NVIDIA(GPU-2): Failed to initialize NVIDIA graphics device on GPU PCI:7:0:0!

I've installed the lastest driver via Envyng-gtx.

I've try on only 2 GPUs on BusID 3:0:0 and 4:0:0 and all was working very well, with Twinview+Xinerama. But when I try with the thirs Graphic Card, it's not working, even writing an xorg.conf like this :

The same xorg.conf with only 2 Videocards and 2 Screens works.

Thank for your help.

I have the same cards here in a system (2 of them) - you may need to download the latest drivers from Nvidia's website and install those. the 9800's needed newer drivers when I last tried it than what was available with envyng.

Let me know if that resolves your driver issue.

Thanks!

Hey,

I've tryed with the lastest 177.82 from www.nvidia.com and still the same problem.

I've wroten blind for the 3th GPU --> PCI:7:0:0 but the 2 screens plugged on this graphic card still stay off. It's maybe not that BusID for my mobo P5N-T Deluxe. I will try with others 1:0:0 2:0:0 5:0:0 6:0:0...

I haven't had any problem with 2x 9800GTX+, when I plugged the third it's not changing anything.. the card works, I've tested it on an other PC succesfully.

Thanks for your help.

The drivers we used were the beta drivers for linux64 v180.17


as described here:

 	Linux x64 (AMD64/EM64T) Display Driver

Version: 180.17
Operating System: Linux x64 (AMD64/EM64T)
Release Date: December 19, 2008

Release Highlights

    * Added support for the following GPUs:
          o Quadro NVS 450
          o Quadro FX 370 LP
          o Quadro FX 5800
          o Quadro FX 4800
          o Quadro FX 470
          o Quadro CX
          o Quadro FX 2700M
          o GeForce 9400M G
          o GeForce 9400M
          o GeForce 9800 GT
          o GeForce 9800 GT
          o GeForce 8200M G
          o GeForce Go 7700
          o GeForce 9800M GTX
          o GeForce 9800M GT
          o GeForce 9800M GS
          o GeForce 9500 GT
          o GeForce 9700M GT
          o GeForce 9650M GT
          o GeForce 9500 GT
    * Added preliminary support for OpenGL 3.0.
    * Fixed a problem with the SDI sync skew controls in nvidia-settings.
    * Fixed a problem that caused some SDI applications to hang or crash.
    * Fixed an nvidia-settings crash when xorg.conf contains Device and Screen sections but no ServerLayout section.
    * Fixed font corruption on GeForce 6 and 7 series GPUs when the GlyphCache setting is enabled.
    * Fixed a memory leak problem when the GlyphCache setting is enabled.
    * Added support for SDI full-range color.
    * Fixed a problem parsing the monitor sync range X config file options.
    * Improved VDPAU error recovery on some GPUs.
    * Improved VDPAU error detection and reporting.
    * Improved VDPAU support for some video bitstreams.
    * Updated VDPAU:
          o VdpDecoderCreate API has changed incompatibly. All client applications must be rebuilt because of this change.
          o For H.264, require the application to tell VDPAU how many reference frames to allow. This allows the application to request more than 4 reference frames.VDPAU should now support level 4.1 reference frame limits on all GPUs (or very close to this limit). The application now has control over this aspect of VDPAU's memory usage.
          o Fix corruption decoding some H.264 streams on some GPUs.
          o Fix a bug that prevented VC-1/WMV3 decode from being allowed on some GPUs.
          o Documentation enhancements and cleanups to vdpau.h.
          o Don't paint the color key to presentation queue targets until the first frame is presented. This should reduce or remove the time the key is displayed before the presented frame is visible.

u can download them from nvidia's site by choosing the beta drivers area under download drivers. Then choosing show all beta drivers in the pulldown box on the new download page.

Hope that helps!

Thanks,

Shane

Me again,

I've installed the beta nvidia driver 180.06 for linux 32bit, still the same way, no display on the 3rd card, even testing several BusID (PCI:1:0:0 PCI:2:0:0 PCI:5:0:0 PCI:6:0:0).

I don't know what to do now, the third card is plug between the 1st and the 2nd.
