Question Xlib: extension "GLX" missing on display ":0.0".

Hi all
I am running Fedora core 2.6.18, and have a NVS 280 PCI graphics card. I am driving three displays, two from NVS 280 and one from my onboard DVI port. I am using intel 915 GM chipset. I get all the three displays up and able to run glxgears on NVS 280 displays. The problem I am facing is that on the onboard when I try running the glxgears I ge the following errors:

Xlib: extension "GLX" missing on display ":0.0".
Error: couldn't get an RGB, Double-buffered visual

when I run the glxinfo I get

/usr/bin/glxinfo
name of display: :0.0
Xlib: extension "GLX" missing on display ":0.0".
Xlib: extension "GLX" missing on display ":0.0".
Xlib: extension "GLX" missing on display ":0.0".
Error: couldn't find RGB GLX visual

For the onboard DVI I use i810 as my driver.

Attached is my xorg.conf file for reference.

I am not sure why openGL is not running on the onboard.
I am not sure where I could post this, as I found a whole lot of information on google but nothing pertains to the problem I am seeing. Any suggestions or feedback would help.

Thanks
Regards.

This is expected behavior. You're trying to run glxinfo on the I810 driven X screen, however the glx module that X is using is from the nvidia driver.

Thanks for the quick update...

So does that mean I cannot run openGl on the i810 display X-screen... Is there any other way I could do this. I need to program all the three X-screens with bitmaps and at the same time...

Any suggestion would be very helpful !!!

No, that is not possible. If you need 3 X screens, then they all need to be NVIDIA GPUs.
