[ccp4bb] 3D graphics linux compatibility question

2013-09-17 Thread Emmanuel Saridakis
Dear BB,

We are still a bit confused about compatibility of graphics cards with 3D 
Coot/PyMol in Linux:

(a) In previous CCP4bb discussions, it was stated that only Quadro cards are 
compatible with Linux setups. But could someone tell me what the minimum 
standard really is: is it Quadro FX380, 2000, 3800 or something else ? The 
nVidia site lists Quadro 3700 and 3800 as the two lowest (cheapest) options 
compatible with Linux 3D. However, different CCP4ers have in the past mentioned 
the other two options as working perfectly or with little trouble.

(b) If a monitor such as the ASUS VG278H , which has an in-built nVidia 3D 
vision emitter which takes its stereo synch from a DVI cable is used, can we 
even use the simpler GeForce GTX670 or 680 ?

As you might imagine, we are on a rather tight budget. Any info would be 
greatly appreciated!

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.



 (b) If a monitor such as the ASUS 
 VG278Hhttp://www.asus.com/Monitors_Projectors/VG278H/#overview ,

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.


 As you might imagine, we are on a rather tight budget. Any info would be
 greatly appreciated! which require the 3 pin mini din port on the video
 card.


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.

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
