"OpenGL Stereo" on QuadroFX 5000
 

Hi
We got a Quadro FX5000 and a Acer GN245HQ Monitor which can do 120Hz.
I have installed nvidia-driver 290.10 and nvidia-settings 260.19.29

Currently the stereo mode seems not to be enabled: both "glxgears --stereo" as well as a medical Software which can use OpenGL Stereo report that the device is not stereo capable.

I know that under Windows there is a Nvidia Control Panel where you can set something like "Enable OpenGL Stereo" (or similar). But under Linux there is no nVidia control panel, and the nvidia settings don't have any "Stereo" button (as far as i could see...)

How can i enable the Stereo Mode for this cards under linux?

Thank You
Jody

What does your xorg.conf file look like?

Hi

This what my xorg.conf looks like:To explain the TwinView setup: I have the Acer monitor on the left side (DFP-0), and a "normal" monitor (Samsung) on the right (DFP-1).

Thank You for any suggestions

Re: "OpenGL Stereo" on QuadroFX 5000
 

Are you using "Stereo" "3" Or "Stereo" "10"? Are you using external IR emitter Or monitor's inbuilt IR emitter?

Also add in xorg.conf:

Section "Extensions"
Option "Composite" "Disable"
EndSection

Thank You for your reply

I don't explicitly use a particular sort of stereo - i only wanted do enable stereo for this monitor so that the applications with stereo options recognize the monitor as stereo-enabled.

I never found any info on how to access any emitter (internal or external)

I have found a test program by bob somers which allows the controlling of nvidias external emitter.

If you have any information on how to control the monitor's internal emitter i would be very thankful for it.


Another problem i encountered: If i remember correctly you need a refresh rate of 120Hz for stereo. By default this moniotor has 60Hz, but i k found out how to set it to 120Hz. However, each time i restart, it is reset to 60Hz. Can you help me here as well?

Thanks a lot

Yes, Stereo is incompatible with the Composite extension.
Please try by disabling Composite.

Also please include the nvidia-bug-report.log file when reporting a problem.

Just add line in xorg.conf file :

Option "Stereo" "10"

OR do : `nvidia-xconfig -stereo=10`

and restartX . You will see blue color led of monitor become green. And check the resolutions and frequency in nvidia-settings.

You can manually set resolution 1920x1080 with 120 Hz

It works!! :)

Thank you very much for your help.

One final question:
When i reboot the machine, and log in, some text in a blue rectangle appears which amongst other things tells you to "turn off stereo if your not watching stereo"

Is the stereo mode harmful for the operation of the monitor?

Thank You
Jody
