[COOT] Hardware stereo setup help
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...

Re: [COOT] Hardware stereo setup help
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 -- Andrew Purkiss X-ray Laboratory London Research Institute Cancer Research UK

In addition to using STEREO mode "10", try adding this section to xorg.conf: Section "Extensions" Option "Composite" "Disable" EndSection Full xorg.conf file included at the bottom of this post.

Re: [COOT] Hardware stereo setup help
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. - J. - Am 02.09.13 23:59, schrieb David Schuller: In addition to using STEREO mode "10", try adding this section to xorg.conf: Section "Extensions" Option "Composite" "Disable" EndSection Full xorg.conf file included at the bottom of this post.

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