Matic,
I am struggling with Ubuntu on this issue.
The Nvidia driver needs the 'Composite' function disabled in order
to function in 3D. This required the use of the Unity-2D package
to disable the 3D used in the Ubuntu desktop effects. This worked
fine in Ubuntu 12.04. Unfortuately the developers have decided
that the eye candy is essential to their desktop and have
deprecated the Unity-2D package(since 13.04). So in a more recent
release of Ubuntu the 'Composite disable' in the xorg.conf with
the Nvidia driver will yield a blank screen and a core dump.
I'd certainly love it if someone could offer a solution aside from
stepping back to an older release.

Dear everybody,
to my recent experience not everything is good in the stereo
world. Since I see that others don't have these problems (and I am
happy/sad to see that the same exact combinations work without
problems) I would just like to add my experience.
For the past 4 months I have been struggling to configure a stereo
setup for viewing structures in Pymol.
I got the VG278HR and PNY Quadro K600 connected over the original
DVI-D cable. Since then I was unable to get anything in stereo on
Linux (tried Ubuntu, OpenSUSE, Fedora). Unfortunately I get a
blank/black screen whenever I use the stereo option in xorg.conf.
Also tried changing the motherboard and CPU but got the same
result.
In Windows the demo stuff from Nvidia works just fine but again I
have problems with Pymol. So far the only way to see anything
connected to molecular structures in Windows was via DVI-to-HDMI
cable but due to HDMI restrictions the quality isn't as good as it
would be over DVI-D. If I use DVI-D that was shipped with the
monitor the quadro card is detected in Pymol but the monitor
doesn't switch to stereo.
I have been in contact with the company that makes Quadro cards
(PNY) but they were unable to help me. I also contacted some very
kind users of CCP4BB and they kindly answered a bunch of question
regarding specific setup options. Thanks again! Still there was no
success so far.
I am slowly giving up on the stereo so if anybody has any
ideas/thoughts what could be wrong/done I would greatly appreciate
any insight.
Kind regards,
Matic

I have the ASUS 27" stereo LCD monitors with built in
emitter connected to Linux WS with the cheaper Quadro cards.
The monitor comes with a special DVI cable that caries the
sync signal and thus it does not need the 3-pin connector.
The new LCD stereo monitors produce superb 3D images that
are much crisper than we used to get with CRT displays.

Hello,
Sorry, if this question somewhat off-top to the actual
discussion, but to my understanding one does need the
3-pin connector to operate 3D under Linux even for the
monitors with the built-in emitter. It appears to be
necessary to guide the emitter, or am I wrong about it?
I'd be thankful if anyone can advise me on that since it
looks like a big problem to acquire the commercial
connectors and cables.
I think I have seen an older discussion on CCP4BB
where the importance of the 3-pin connector was
emphasized...
Alexey
