When gdm start, nvidia logo is displayed so I know that nvidia driver is
working. But when I start glxgears, I get:
$> glxgears
Xlib:  extension "GLX" missing on display ":0.0".
Error: couldn't get an RGB, Double-buffered visual

Can someone tell me what am I missing?

My nvidia card is:
01:00.0 VGA compatible controller: nVidia Corporation NV11 [GeForce2
MX/MX 400] (rev b2)

and the kernel I am using is 2.6.21-1.3228.fc7.

Look in your /var/log/Xorg.0.log for EE which should show the error.



That helped. It was telling me that GLX cannot be used with Composite extension enabled. Well, I was assuming the by commenting out the Composite extension in xorg.conf file I could prevent it from being enabled. Turns out that I have to explicitly disable it in xorg.conf file. So using
Section "Extensions"
         Option     "Composite" "Disable"
 EndSection

worked. Thanks.
