Could you give more details as to *what* Linux systems? PyOpenGL is=20
primarily written on Kubuntu machines (12.04 and 15.10) and on both GLE=20
tests using PyOpenGL-Demo and OpenGLContext are all working.

Are you sure that you've created a GL context before calling any GLE=20
functions?

I was working on getting the final 3.1.1 release out today, but it seems=20
that will need to wait until we address this (afraid I haven't been=20
monitoring my PyOpenGL folder as I worked on my conference presentation).

Take care,
Mike
