xpra can use PyOpenGL without PyOpenGL-accelerate but having both
installed is a lot better.
(not sure why Debian and Ubuntu don't package PyOpenGL-accelerate)

Yes:

Your installation of PyOpenGL + PyOpenGL-accelerate is broken: the
versions must match exactly and Ubuntu 16.04 ships an outdated version
of PyOpenGL, then you must have tried to install a newer version of
PyOpenGL-accelerate on top.

That should work fine.
