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

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

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

Take care,
Mike
