The emitter is recognized during bootup. If you plug it in after bootup, 
it won't work.

Re: [COOT] Hardware stereo setup help [SOLVED]

2013-09-03 Thread Arnaud Basle 

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

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.

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

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...

Re: [COOT] Hardware stereo setup help

2013-09-02 Thread Andrew Purkiss 
Dear Arnaud,

You need stereo mode 10 (and not 3) for the modern 3D vision setup. You
need to make sure that the 3D vision 2 emitter is plugged into a USB
port as well (assuming that you don't have a screen where the emitter is
integrated).

Hope that helps,

Andrew
