[3dem] stereo LCD displays

I recently set it up (Acer 27" active stereo) and have it running with no problems under Ubuntu 11.04. It was not absolutely trivial to get going though.
The issues I'm aware of:

1) You need a dual-link DVI port and cable to support the appropriate refresh rates
2) Windowed stereo is only supported on Quadro series Nvidia cards, and you must use the mini-DIN plug to run the shutter glasses transmitter. USB-only does not work in Linux.
3) If you are running a dual-monitor setup, things can get a little trickier, even if you are only running stereo
  on one display. For example, my second (non-stero) display also requires dual-link DVI. That means that you have to have a powered DisplayPort adaptor
  for the second output from the Quadro card.
4) You must run both monitors (if present) from the same video card for stereo and the desktop to both work properly.
5) A little custom tweaking of the X11 config file is required

We also have a number of the passive stereo displays. The ones that use the LCP/RCP passive glasses, and I must say that they are massively
better than the active systems in all respects except for one. They don't require a special video card, and work with Chimera out-of-the box. 
No special configuration. No nothing. Just plug it in and it works immediately. The only downside is the loss in vertical resolution producing a mild
'jaggie' effect on slanted lines. Other than this, they are great !
