Triple Head with two cards on Ubuntu 12.10

loloemr · 11-21-12, 07:04 AM

Hi everybody,

I have a HP desktop with two Nvida cards.

lolo@meije:~$ lspci |grep VGA
04:00.0 VGA compatible controller: NVIDIA Corporation GF108GL [Quadro 600] (rev a1)
05:00.0 VGA compatible controller: NVIDIA Corporation GF108GL [Quadro 600] (rev a1)

and I have three monitors :

Dell 17
HP 24'
Acer 17'

I'm currently running Ubuntu 12.10, with nvidia proprietary driver 304.51, but I don't succeed to setup a triple head configuration like
DELL 17 1280x1024 - HP 24 1920x1200 - ACER 17 1280x1024

I have tried some xorg.conf I have found on the net but without success.

If you need more information about my system ..

Thanks a lot

Hi!

Please check /usr/share/doc/NVIDIA_GLX-1.0/README.txt for "BaseMosaic". There's also a configuration example for a 2x2 setup:

Code:

 nvidia-xconfig --base-mosaic --metamodes="GPU-0.DFP-0: 1920x1024+0+0,
    GPU-0.DFP-1: 1920x1024+1920+0, GPU-1.DFP-0: 1920x1024+0+1024, GPU-1.DFP-1:
    1920x1024+1920+1024"

However, I have no idea how well that works with three displays of different geometries.
Once you got it working, I would appreciate it if you could post some details.

regards

Bernhard

Thank you very much, it solved perfectly my problem using :

Code:

sudo nvidia-xconfig --base-mosaic --metamodes="GPU-0.DFP-0:1280x1024+0+0, 
GPU-0.DFP-2: 1920x1200+1280+0, GPU-1.DFP-0:1280x1024+3200+0"

The only point is that ligthdm is buggy so I use gdm (otherwise, any desktop manager fails).

Very Happy this morning
