I am quite sorry that there is a similar thread named "LinuxQuestions.org > Forums > Linux - Distributions > Fedora > Instructions for installing Nvidia driver on FC3" about this problem. But I can still not find the answer. I am just a fresh Fedora user . Please give me some help.

The original resolution was 1024*768. Then I changed it to 1280*960. The following errors came out.

************************************************************************
[c@g tp]$ ./tp001
freeglut (./tp001): OpenGL GLX extension not supported by display ':0.0'

[c@g markerless_camHand]$ ./main
(main:3023): GdkGLExt-WARNING **: Window system doesn't support OpenGL.
************************************************************************

I tried to returned to the original resolusion of 1024*768.
But the error is the same.

DO: rpm -qa |grep xorg-x11-Mesa-libGL
OUTPUT: xorg-x11-Mesa-libGL-6.7.0-2
xorg-x11-Mesa-libGLU-6.7.0-2

sorry to post this thread. it seems that it is just a simple problem.

when i changed the resolusion, the driver is renamed in the file of /etc/X11/xorg.conf.
