Thanks Rafael and Jason,
I upgraded to the latest driver version for Linux i.e 275.19 and now have
stereo working with some caveats.
I am running the PLANAR SA2311 at 120 Hz and 1920x1080 resolution and the
stereo is rather finicky with the nvidia 3dvision setup.
I see a lot of random stereo image flips , i.e suddenly during a rotation
the parts of the molecule that are going into the plane of the screen, now
start coming right at you. Also during stereo viewing , the distant parts of
the molecule seem to not show up as stereo sometimes , i.e I see two helical
chains , instead of one stereo chain while at the same time the parts of
the molecule closest to you are nicely displayed.
Whenever that happens re-sizing the screen , makes the stereo jerk back into
sync ..till a few minutes later it goes out of whack again.
Here are what I tried to get the stereo visual to stay stable and behave:
1) I tried fiddling with the scroll wheel at the back of the cutoff-pyramid
emitter box . But didnt see any difference.
2) A dark or bright room still had no impact
3) I tried turning off the other LCD sitting next to it ..and this didnt
have any effect
4) The emitter position also didnt seem to effect the stability of the stero
visual
I noticed from the xorg.conf that I am using a metamode 1920x1080_120. Does
anyone have a modeline for the SA2311W that gives them stable stereo.
Could it be that the 275.19 driver is worse than other earlier versions
longing for the stable CRT stereo from the past
