GLX is the OpenGL X extension. It contains extensions to the X server and library, as well as a API for programmers. GLX integrates OpenGL with X, it provides the glue code to easily do OpenGL in X, as well as several commands to test and check on things. GLX should be included in any modern day X server distribution.
