nV News Forums - Missing stereo effect: No NVIDIA 3D Vision capable display connected.

Hi,

I have two PC's, one Quadro 3800 card and one CRT monitor. I also have the nvidia 3d vision glasses and usb transmitter. The first PC is running Windows and the 3d vision is working there (stereo using the nvidia glasses).

I then move the 3800 card and monitor to the other PC, running Linux 2.6.18 and nvidia driver 256.53. I made sure the monitor runs in the same resolution (800x600) and frame rate (120 Hz) as it does on the Windows PC.

I try running

Code:

glxgears -stereo -fullscreen

and it runs, no worries. But when I look through the glasses, no stereo effect appears. I'm expecting this to work.

I can't find anything but this message from Xorg.0.log:

Code:

(WW) Sep 14 16:22:35 NVIDIA(0): No NVIDIA 3D Vision capable display connected.

which is confusing since the glasses work on the Windows machine.

The usb transmitter lights up and has a steady green light. How can I tell if glasses are flipping? What's causing the Xorg.log warning message?
