3D projection from Linux fails
Hi, On Centos 5.6 with driver release 310.32, we can display 3D to LG and Asus monitors with no problems. When the stereo view is enabled, the emitter goes bright green, the 3D Vision glasses work as expected, and all is well. If we disconnect the monitor and connect an NEC V300X or NEC V300W instead, the display shows the two superimposed images as expected, the emitter goes bright green, but the glasses do not respond at all. They are definitely charged and turned on, but the dimming I expect when 3D is active is not present, the view through the glasses does not change when I hold the button down (normally changes from 3D to clear), and I can still clearly see two images on the projected screen. The NEC projectors are configured for 3D with the NVidia option, and they do show the superimposed images, but there is simply no switching in the glasses. Can anyone suggest what is wrong here?

Wow, tumbleweed... Does no-one have anything to contribute on this problem?

You might try the Dev forum and post in the linux section. I do not know anything about linux, but perhaps you can gleem something from a post a few weeks back. https://forums.geforce.com/default/topic/532872/3d-vision/3d-not-working-on-linux/
