Hi PyMOLers

 

We recently bought Asus V278H monitors, which displays nice stereo under Linux (Ubuntu 12.04).  The monitors were bundled with Nvidia 3D vision v2 glasses. We have Quadro FX5800 cards, but we do NOT use the 3-pin stereo port, but rather the built-in emitter in the monitors. I have pasted my notes from the installation below. Is works with PyMOL as well as other OpenGL applications, such as VMD, Accelrys Discovery studio, CCDC GOLD/Hermes, Yasara, etc.

Cheers,

Asus VG278H flat panel 3D screens and Ubuntu 12.04

These screens 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

 

/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

 

/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

Note!!

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

/etc/X11/xorg.conf

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

Subject: [PyMOL] Viewing PyMol in 3D

 

Hey everyone,

 

Does anyone have experience setting up pymol to be viewed in 3D with glasses? I’m hoping to build a system for this purpose.

 

From what I have read, I will need a recent NVidia Quadro card and a 3D-capable LCD monitor with a resolution of at least 120Hz. I’m not sure if I need to be more specific than that (if there are particular cards/monitors that are known to work/not work). I’m also not quite sure if this is possible on Windows 7. I’ve seen reports of people doing this with Windows XP and Vista, but I would prefer to avoid those operating systems.

 

Any suggestions or advice would be greatly appreciated.
