Problems running JOGL-Demos

When I try to run one of the jogl-demos using javaws, I get the following error.

An error occurred while launching/running the application.

Title: JOGL Infinite Shadow Volumes Demo
Vendor: Sun Microsystems, Inc.
Category: Unexpected Error

glXGetConfig failed: error code GLX_NO_EXTENSION

I’m running Gentoo Linux with a GeForce2 MX/MX 400.
In my XF86Config file I load the GLX extention.

Have you tried to run the jogl demos using a simple call like this one :

java [demo_name]

If this doesn’t work, I think it could be a driver issue…
