[PyOpenGL-Users] Python 3 crash when running on optimus card

[Ákos T. <dxm...@gm...>]

Hi,

I recently started using pyOpenGL with Python 3.3 on Ubuntu 13.10. I am in
the unfortunate situation of owning a laptop with a switchable (Optimus
technology) dedicated video card. With the most recent version of pyOpenGL
(3.1.0b1) installed, the program crashes quite seriously when running the
line "from OpenGL.GL import *" - to the point where Ubuntu actually opens
an error dialog for this. This problem is specific to Python 3 with optirun
- in C++, OpenGL works on the optimus card without any hiccups, and version
3.0.2 with Python 2.7 also works without a problem.

Tests concluded so far:
- Python 2.7, pyOpenGL and accelerate version 3.0.2 with or without
optirun. No problems.
- Python 3.3, pyOpenGL and accelerate version 3.1.0b1 without optirun - no
problems but the intel card only supports openGL contexts up to version
3.1, which is far behind what I require.
- Python 3.3, pyOpenGL and accelerate version 3.1.0b1 with optirun, crash
on import. In the pastebin link below is the output of python3 -vvvvvc
"from OpenGL.GL import *".

Thank you in advance for your help,
