Re: [PyMOL] NVIDIA 3D error

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.

[edit<http://pd.novo.dk/mediawiki/index.php?title=Linux_workstations&action=edit&section=5>] /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?
