Hi,
Thanks all your useful comments it works now. As far as I can tell the
important keywords in xorg.cong are:
In Screen section:
| Option"UBB" "True"
Option"Stereo" "10"|
As well
|Section "Extensions"
Option"Composite" "Disable"
EndSection|
I think under linux the emitter still need to be connected to a USB for
power but indeed the sync signal comes from the 3 pin connector. Somehow
I managed to get the emitter going to error and glowing red. The problem
was solved by rebooting into windows and back to linux.
Very nice to have active 3D (we have also a passive Zalman 3D but I
prefer active 3D).
Cheers,
Arnaud

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"

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
