[Chimera-users] Problem with multiple monitors and NVidia 3D Vision - any suggestions ?

[Steven Ludtke]

Hi. I just set up a 3-D vision compatible stereo monitor as a second display on my desktop. I have a Quadro 4000
video card and am running 64 bit linux (Ubuntu 11.04) with the latest 270.41.06 Nvidia driver. If I only have 
one monitor (the stereo capable one) attached to the machine, I can get stereo working (looks very nice), but
if I have the second non-stereo capable monitor connected at the same time, it will not initialize the stereo display mode
(on either display). I have it configured using Xinerama, so the 2 displays are on separate X-servers. Even
when I disable Xinerama, and the second display is running on a completely independent Screen, it still won't
go into stereo mode. Here are the relevant lines from the Xorg log file:

So, the logfile seems to indicate that it's initialized correctly, but when chimera tries to open a Stereo window,
it raises an error  :^(

Here are the relevant xorg.conf sections:

Anyone else have a Stereo configuration with dual monitors working ?
