problem solved!!! Re: 3D Vision in Linux
man nvidia-xconfig gave me the clue to run this:
Which added a section to the xorg.conf file:
Option "Composite" "Disable"
Once I did that, logged out of gnome, then logged back in, the green light on the emitter went on!
But it turns out, I still had one more problem to fix.
I had to use the DVI to DVI cable that came with the Acer Display, not the HDMI to DVI cable that came with the 3D Vision Kit. Then, I had to log out and back in again and voila...I finally have 3D stereo working now on an LCD display with nVIDIA's 3D Vision on RHEL 5.
