Hi,
under linux, USB support will not work as far as I am informed. So,
better to use the 3-pin for both operating systems.
Not sure the nvidia demo is a useful reference because it can send a
HD-TV 1920 × 1080 pixel @ 24 Hz signal to the monitor (what monitor
are you using and how is it connected, HDMI, DVI-D???).
Under windows, you have to set a few things in the nvidia system driver:
1) change monitor settings to advanced stereo
2) change 3d options to 3d opengl stereo with stereo activation on
You have to play a little around here.
Under Linux, you have to set a few things in the xorg.conf file by hand!
To find out why it is not working, send us of the xorg.conf file the
sections Monitor to Extentions. This will help to locate the problem.

In addition to using STEREO mode 10, try adding this section to
xorg.conf:
Section Extensions
Option Composite Disable
EndSection

Dear Coot and Pymol users,
I have the same problem with both softwares so I thought I would send
a joined message.
We recently acquired a quadro 4000 with a 3-pin connector and the
NVIDIA 3D Vision 2 kit (suppose to be supported by NVIDIA on linux
for openGL applications
http://www.nvidia.com/object/quadro_pro_graphics_boards_linux.html)
I have inserted /etc/X11/xorg.conf in device section the following:
option stereo 3 following instructions here
(http://us.download.nvidia.com/XFree86/Linux-x86/310.40/README/xconfigoptions.html)
I am using Mint 13 (based on ubuntu) and the NVIDIA drivers are 319.32.
When stating pymol using the following: pymol -S -t 1, I get the
following error message: Error: The requested stereo 3D
visualization mode is not available.
Coot give me the following error when switching to hardware stereo:
WARNING:: Can't enable stereo visual - falling back
so I guess I did not installed properly my drivers but I am stuck in
what to try next. Any help from those of you who managed to get
hardware stereo to work would be greatly appreciated (I am even
willing to try a different linux flavour if need be).
I would like to add that the hardware works fine (at least the NVIDIA
demo stuff) on windows 7 but even under windows i could not get
pymol/coot to work. Both switch to stereo hardware and the display
get blurry but the shutter glasses do not work...
Cheers,
Arnaud
