EGL for Wayland EGLPlatform

[pradyparanjpe]

Issue:

- Module import fails for wayland.
- `PYOPENGL_PLATFORM=EGL` doesn't help. (Error is thrown with AND without the variable set)

Command call

$ PYOPENGL_PLATFORM='egl' python -c 'import pyopengltk'
$ python -c 'import pyopengltk'

Raw Traceback:

I'm seeing this problem, is there any further information on this?

I didn't find a machine to reproduce. Can you run glxinfo and/or glxgears via XWayland?

[drummondj]

glxinfo output is here: https://gist.github.com/drummondj/b002bc45a4ec5cf2197c41b6267c67b4

glxgears runs fine

[jonwright]

So I finally found a machine running wayland. You need to do:

$ PYOPENGL_PLATFORM=glx python3 cube.py

... and it should use glx. Can you let me know if that works for you?
