Can you run this code within the QGIS python shell?

from PyQt5 import QtOpenGL

addresses issue #299 : additional test if PyQt5.QtOpenGL is available

Installing python bindings for Qt5 OpenGL fixed the problem

‌

sudo apt-get install python3-pyqt5.qtopengl

I will probably add that to the installation guide as optional, or include this in the FAQ section
