I get an error when trying to use VPython on Ubuntu 11.10. I installed the program using the Ubuntu Software Center. All the additional instructions that I've found are either for much older versions or confuse me. What do I need to do in order to use VPython? I am running Python 2.7.2.

It seems like the problem is openGL related.

Try updating your graphics driver (make sure you have 3D acceleration enabled)

Also try installing the dev package for libgtkglextmm-x11, someone on the ubuntu forums seem to have solved their problem this way.
