Thank you all for the quick replies. I did leave out some specs, but I
really wanted to know what others have found. Sadly, it's no different
than my findings. I am at a small undergrad only university - low on
resources but big on ideas for teaching students. This is not research
based, so I don't have a grant to buy one system for research (I do
solve structures and I can buy one system, but I need more for a
class). Instead, I'm trying to teach a class - we have 6 workstations
that are shared among the students. We solve a crystal structure as
part of this class. Stereo is nice but not necessary - though as a
teaching tool it's invaluable.
Switching to the nvidia system works - we have that here for one
classroom - the problem being active stereo is a nuisance. It can
flicker - looking away can cause problems (with a larger classroom), and
it's just not the way to go (the glasses are expensive, I can go on and
on).
I think passive stereo is the beat all end all - but I can't buy a
zalman monitor to save my life (I have literally had 3 of these in
shopping carts - and one went as far as to charge my card only to refund
me 3 days later due to lack of stock). That does make me worry as to
replacing it later in life should I get 6 and they crap out on me.
When I was at Argonne, they have a polarizing filter that fits on the
front of a monitor. You can turn it on and see stereo through that, I
think it's basically a Zalman filter. Does that sound right - and if so
- is that something somebody out there has?
Thanks again - your help is invaluable. By the way - if I ever do
replace this, is anybody in the market for some old emitters, video
cards, and glasses (I have 14 pair of the 3D glasses - crystal eyes
knock-offs, sorry the company escapes me at the moment, but they are
good glasses).

Hello Dave,
I would like to replace the CRT's with some sort of LCD thing.
You have two options for stereo on linux. The Zalman passive stereo route,
which you tried, or the active stereo route, which means an Nvidia 3d
Vision emitter/glasses combo and a 120 Hz LCD.
The glasses/emitter kit is here:

And you need an Nvidia Quadro FX 3700 or higher to run them on linux:

There are several 120 Hz LCDs available right now. Some links to models
and additional info on set up are on our website:

I hope this helps.
