This may be a red herring, but earlier this year we purchased several ASUS 
VG278H monitors and initially could not get even the "glxgears -stereo" demo to 
display in stereo.  We checked all of our xorg.conf settings with NVidia and 
still no stereo.  However, when we upgraded from RHEL5 to RHEL6 everything 
worked perfectly.

One point of difference between our setup and the one quoted below is we have 
Stereo set to 10 and not 11.  11 is for VisionPro which uses RF instead of the 
IR emitters.

Hi Dick

A hint about your setup would be helpful.... :-)  I Assume you use Linux.

Our ASUS VG278H monitors works fine in 3D stereo with Nvidia Quadro FX5800 
cards. I have pasted my notes about how I configured X.


Cheers,
Esben



Asus VG278H flat panel 3D screens and Ubuntu 12.04

These screen have built-in emitters that actually work under Linux, with Nvidia 
drivers version 310 or newer. (These drivers are packaged in Ubuntu 12.04, so 
they're easy to install)

Install by closing X and install:

 sudo service lightdm stop

use Ctrl-Alt-F1 to swith to a text console and login (possibly, but not 
strictly necessary) as root

 wajig install nvidia-experimental-310

[edit<http://pd.novo.dk/mediawiki/index.php?title=Linux_workstations&action=edit&section=2>]
 /etc/lightdm/lightdm.conf

This file is very important for geting the right video mode for the login 
screen (via the script in /etc/X11/set_1920x1080.sh, otherwise the X-server 
doesn't start at all). It also makes sure that the username has to be typed 
instead of selected from a list (very important when the system has many users)

[SeatDefaults]

user-session=ubuntu

greeter-session=unity-greeter

greeter-show-manual-login=true

greeter-hide-users=true

display-setup-script=/etc/X11/set_1920x1080.sh

session-setup-script=/etc/X11/set_1920x1080.sh

[edit<http://pd.novo.dk/mediawiki/index.php?title=Linux_workstations&action=edit&section=3>]
 /etc/X11/set_1920x1080.sh

This script calls the xrandr tool to set the videomode

#!/bin/bash

xrandr --output DVI-I-3 --mode 1920x1080 --rate 120

[edit<http://pd.novo.dk/mediawiki/index.php?title=Linux_workstations&action=edit&section=4>]
 Note!!

It seems that when everything is installed, there are still some tweaks to do 
(not completely sure though)

 *   Reboot
 *   For stereo to work the first time, I had to stop lightdm (see above), 
switch to a text console and login as normal user, then do startx to start the 
X-window system. Now check if stereo works. If so, then switch back to the text 
console and kill the X-server (Ctrl-C). The restart lightdm and login from the 
graphical login screen. Then it should work.

 /etc/X11/xorg.conf

I dont know how important the xorg.conf file actually is, but here's my copy

Subject: [PyMOL] NVIDIA 3D error


I think I have tried all the solutions available.  I continue to get: error: 
the requested 3d display mode is unavailable.  I can run all the examples; 
apparently correctly.
ASUS  VG248 monitor
NVIDIA quatro K600 video card
NVIDIA 3D vision
Suggestions?
