Hello,

I have been having a problem getting stereo to work on the lab's new
flatsceeen ( i know, i know..... CRTs = much better but i think the
purchaser was overcome with flatscreen lust).

I am using a Dell 3007WFP (2560x 1600, refresh rate = 60hz) attached to
nVidia Quadro FX 4500 graphics card with the eDimensional stereo glasses. I
am using the current drivers from livna (100.14.09-2lvn7) on a Fedora7 box
with the 2.6.21_1.3228 kernel.

When I try to get Pymol or Coot to use stereo, no luck: Coot tells me that
the hardware does not support quad buffered stereo. To the best of my
knowledge I have the xorg.conf file correctly configured (see below) and I
am wondering if anyone has run into these problems before or if somehow the
livna driver can detect a refresh rate that is suboptimal and therefore
refuse to start stereo. Perhaps there is also the issue of the kernel? I
don't know, but I would appreciate any help.

Below is my xorg.conf file and you can see I have 'Option "Stereo"' set to
"3". I have fiddled around with many of the options in the xorg.conf file -
basically trying every variation that i found other people had used.
However, still no luck, which makes me think there may be some driver or
kernel issue.

Anyhow, any suggestions would be greatly appreciated (I would like to get
this monitor work before falling back on a CRT - if the flicker is terrible,
there will be no choice but it seems others have been using these monitors
for stereo).

thank you,
