3D Vision in Linux

m0l0ch · 10-06-10, 03:55 PM

Hi all.

As the title states, i'd like to use 3d Vision under Linux.
My graphics card is Nvidia Quadro FX 3700.
I have installed the nvidia driver (256.53) and it works with my Acer H5360 Projector.
Then I enabled 3d vision stereo in the configuration file (Option "Stereo" "10").
After that, the following command worked.

Code:

glxgears -stereo

I saw the usual 3 gearwheels, but it looked like two images (kind of like when you're drunk).

When I restart the X-Server, the Beamer tells me that it's running in 60hz, but i think it should be 120. If that is the issue, how can i solve it?

Short update on this:

I got the 120Hz working, but still no 3d.
I start to doubt that my 3d glasses are operational.
When I turn them on, the light turns green for a short time, then it goes away. Is that normal?

3D Vision doesn't work under linux...
Stereoscopic only works with Business Quadro Cards, starting at prices near to 1000 $!

First of all, thank you for your Reply.

I am aware of that.
As I read on nvidia.com (http://www.nvidia.com/object/quadro_...rds_linux.html), the Quadro FX 3700 is one of those cards that are supported. Also my beamer is on the list of supported display devices (http://www.nvidia.com/object/3d-visi...uirements.html).

I have also purchased the upgrade kit from PNY, and the infrared Port (connected via USB and the onboard stereo connector from the upgrade kit) goes bright green when I start glxgears in stereo mode.

I am running 64-bit RHEL 5.5 on an HP Z600 workstation and purchased a 3D Vision Kit, but also am unable to get the stereo graphics to work.

I successfully installed the latest nVIDIA driver (260.19.29) for the Quadro FX 4800 graphics card from the "telinit 3" non-X-windows mode.

I have connected the 3D emitter to both the USB port and the 3-pin DIN connector of the Quadro FX 4800.

I also am using the HDMI/DVI cable that came with the kit to connect the computer to the 3D Vision compliant Acer GD235HZ 120 Hz LCD display.

In the xorg.conf file, I set the Stero option to "10", as directed in the README for xconfig options with that 260.19.29 driver:
http://us.download.nvidia.com/XFree8...igoptions.html

I have tried rebooting the computer after doing all this.

The emitter keeps flashing red and I can not get stereo to work.

For example,
glxgears -stereo
Error: coudn't get an RGB, Double-buffered, Stereo visual

After hours of searching on the forums, I have been unable to find a solution.

The documentation on the Quadro FX 4800 even claims Full OpenGL Implementation on Linux.
And according to the URL for the Quadro cards, I should be able to get 3D Vision to work.
http://www.nvidia.com/object/quadro_...rds_linux.html
On that URL, there's a link for supported drivers and displays, which indicates my system is a go.

It would be great if someone could help me figure out what I am doing incorrectly!

I looked at the /var/log/Xorg.0.log and found a hint of the problem:

(**) NVIDIA(0): Option "Stereo" "10"
(**) Jan 14 14:19:21 NVIDIA(0): USB IR emitter stereo requested
(**) Jan 14 14:19:21 NVIDIA(0): Enabling RENDER acceleration
(II) Jan 14 14:19:21 NVIDIA(0): Support for GLX with the Damage and Composite X extensions is
(II) Jan 14 14:19:21 NVIDIA(0): enabled.

(WW) Jan 14 14:19:23 NVIDIA(0): UBB is incompatible with the Composite extension. Disabling
(WW) Jan 14 14:19:23 NVIDIA(0): UBB.
(WW) Jan 14 14:19:23 NVIDIA(0): Stereo is incompatible with the Composite extension.
(II) Jan 14 14:19:23 NVIDIA(0): Disabling stereo.

Any ideas on how to fix this?

man nvidia-xconfig gave me the clue to run this:

nvidia-xconfig --no-composite

Which added a section to the xorg.conf file:

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

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.

Mr K

Read your thread with initerest.

I am trying to find out whether there is a LINUX version of the 3D Glasses Med test as i only have the Windows version to hand. Have you used the test / Gratefull for any advice.

Thanks.
