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,
Esben
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)
* 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
# nvidia-xconfig: X configuration file generated by nvidia-xconfig
# nvidia-xconfig: version 310.14

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.
