CentOS - Nov 2005 - App not finding /dev/nvidia0 for /dev/dri/card0 not found on inspiron 8200 with nvidia chipset

I have source for a program that is attempting to open
/dev/nvidia0 then on failure open /dev/dri/card0
to get some vsync settings.

Neither of those two files is found on my laptop in /dev.
Is this because of udev?

I cant find anthing in /dev that might be used instead.

Any ideas on what to open to read vsync information
from X windows?

Thanks,

Jerry

No, /dev/nvidia0 exists on my centos 4.2 box in /dev
You should check that you have nvidia's drivers installed correctly
and that the nvidia module is loaded by checking with lsmod.

I think xdpyinfo gives you this. I can't remember.
