Dont get G200 instead go for RIVA TNT2 it's far much better if you are
serious graphics coder or even gamer becaue it supports
Vesa/VBE  3.0, OpenGL, DirectX and is a better performer,,,,,, <<<i dont
know much on G200 but i have a friend who has swapped his G200
for TNT2

I dont actually support you here because OpenGL is only the core library
which is system and platform independent and

GLX is used on Unix OpenGL implementations to manage interaction with the X
Window System and to encode OpenGL onto the X protocol stream for remote
rendering.

Mesa3D is the non official implementation of OpenGL on Linux and other
platforms by Brian Paul.

GLUT is the GL Utility Toolkit which is the system Indepentdent Windowing
API by Mark Kilgard


GLU is the OpenGL Utility Library. This is a set of functions to create
texture mipmaps from a base image, map coordinates between screen and object
space, and draw quadric surfaces and NURBS.

any case because a OpenGL program on Linux cant function withought using
Mesa3D libs and secondly it

Mesa3D not MesaGL ((((((IMPORTANT)))))))))

It's an extension ......

Nope I can render scenes with Mesa3d on X withought using GLX ..............

Yup 1!!! this thread has been a interesting one......
