Hello,
I re-post my contribution from 17 may 2017.
Software versions and hardware may be obsolete, but some of the information may still help.

Subject: 3D graphics under linux for coot, pymol and chimera

Hello,

we just wanted to share our experience in finding a configuration which allows to use 3D graphics under linux using Nvidia GeForce 3D glasses.

We had quite a hard time to find a configurations which works correctly.

We finally used Debian linux with a xfce desktop. Other recent desktops use a tiling which is not compatible with 3D graphics.

The hardware consists of

  • a DELL Precision T5810  desktop computer with an Nvidia Quadro M4000 (8 Gbyte memory, 4 DP) graphics card
  • Nvidia GeForce 3D Vision 2 (NVIDIA GEF 3D VISION 2 GLASSES KIT) active stereo glasses
  • a stereo connector PNY Quadro 4000 3D for the synchronization of graphics card and glasses
  • an ASUS 24" LED 3D - VG248QE display
  • a DisplayPort-DisplayPort cable

The Nvidia linux drivers from version 367.57 can handle the current version of the Nvidia glasses.

For an obscure reason a direct DP-DP connection between graphics card and display is absolutely required in order to obtain fully working stereo. If a DP-DVI dual link adapter is used, the stereo does not work on the top and the bottom part of the screen. This is true for a native DELL active adaptor or generic models. The exact reason remains unresolved, but the solution is to use a direct DP-DP connection. This limits the available choice of displays which require 120 Hz for 1080*1980 screen resolution and a DP input. We have been choosing a “Nvidia 3D ready” model.

There has been a considerate about of exchange about this problem on

https://devtalk.nvidia.com/default/topic/992892/linux/partially-working-stereoscopic-effect-with-3d-vision-under-debian-linux/

The setup comes with a price tag of about 1600 € free of taxes.

coot, pymol and chimera work straight without problems in hardware stereo mode. The experience is absolutely great.

Best

Wim
