Hello,
Is anyone using nvidia quadro 4000 graphics card for linux environment to see stereo in pymol, coot, O or similar programs? If yes, I like to buy that.
Thanks...

Yes, we have a Quadro 4000. It seems to work on both Fedora 15 and Scientific Linux 6.1.


I do recall a bit of grief in that the default nouveau driver did not properly recognize the Q4000, possibly because it is a new model; so you will have to know what to do in text console mode to get the proprietary driver working.

This should do it for SL6.1:

# first, enable the elrepo repository:
rpm --import http://elrepo.org/RPM-GPG-KEY-elrepo.org
rpm -Uvh http://elrepo.org/elrepo-release-6-4.el6.elrepo.noarch.rpm

# then you can install the driver. This automatically takes care of blacklisting the nouveau driver.
yum -y --enablerepo=elrepo install kmod-nvidia

You will need to tweak the xorg.conf file to add the stereo line and disable composite.
A  /etc/X11/xorg.conf file for SL6.1 attached.

Detailed instructions will vary with your Linux distribution, of course.

Cheers,

I have a Quadro 3800 paired with an Acer GD235Hz with the computer running Ubuntu 10.04 LTS and the standard NVIDIA linux driver.  Hardware stereo works pretty well in Coot, though it has a habit of inverting occasionally.  Pymol works well.  Have not tried O.
