Re: [ccp4bb] 3D graphics linux compatibility question

2013-09-17 Thread Jose Duarte 

Hi Emmanuel

Here we have tried the nvidia Quadro 2000 with two different monitors 
(both with the built-in IR emitter, thus with synching through DVI): 
ASUS VG278HR and BenQ XL2420TX. The setup works perfectly well in Linux, 
both pymol and coot work without issues. Unfortunately we have no 
experience with other nvidia cards, so can't comment on that.


Hope it helps

Jose

Use the 3700 with the external nvidia emitters (these require the 3 pin
mini din connection from the emitter into the video card) and 120Hz LCD's
that don't have built-in nvidia emitters.

No, I've tried this with a GTX680. You cannot use a GeForce in Linux with
monitors such as the Asus VG278H with built in nvidia emitters and the
official nvidia drivers to get 3D. You have to have a quadro card with a
G8x GPU or better. In this case the cheapest card that would work is the
Quadro FX 370 (not a typo, this is a different card from the 3700). We use
a Quadro 600 or K600 with our Asus VG278H to get 3D.

The VG278H is not a cheap monitor. You may be able to get nvidia 3d vision
kit (make sure the model # comes with the 2.5mm vesa to 3 pin mini din
cable since some don't, esp. the ones bundled with 120Hz monitors) + quadro
3700 + regular 120Hz monitor for slightly less than the price of the VG278H
+ quadro.
