Re: [ccp4bb] 3D stereo and pymol

[Wim Burmeister]

Dear Christine, here you can find my xorg.conf file. https://app.box.com/v/xorg-conf I gave some replies below. Sorry for the late answer, I do not read the ccp4bb every day.

Yes It would be very helpful. We are just setting up a new system.

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.
