Can't create window on Wayland 3.36

Hi Florian, Using pyGLFW 1.11 on Wayland I get the following message when creating a window: …

  File "/home/aanjos/.local/lib/python3.8/site-packages/glfw/__init__.py", line 1156, in create_window
    return _glfw.glfwCreateWindow(width, height, _to_char_p(title),
  File "/home/aanjos/.local/lib/python3.8/site-packages/glfw/__init__.py", line 616, in errcheck
    _reraise(exc[1], exc[2])
  File "/home/aanjos/.local/lib/python3.8/site-packages/glfw/__init__.py", line 52, in _reraise
    raise exception.with_traceback(traceback)
  File "/home/aanjos/.local/lib/python3.8/site-packages/glfw/__init__.py", line 595, in callback_wrapper
    return func(*args, **kwargs)
  File "/home/aanjos/.local/lib/python3.8/site-packages/glfw/__init__.py", line 808, in _handle_glfw_errors
    raise GLFWError(message)
glfw.GLFWError: (65544) b'Wayland: Focusing a window requires user interaction'

I’ve tried the “fix” I’ve found on one of the solved issues:

if sys.platform.startswith("linux"):
            if "wayland" in os.getenv("XDG_SESSION_TYPE", "").lower():
                glfw.window_hint(glfw.FOCUSED, False)

However, I get the following:

File "/home/aanjos/Documents/git_sandbox/g3D/g3D/Drawable.py", line 36, in vbo_vertex_data
    gl.glVertexAttribPointer(layout_pos, 3, gl.GL_FLOAT, False, 0, None)

  File "/home/aanjos/.local/lib/python3.8/site-packages/OpenGL/latebind.py", line 63, in __call__
    return self.wrapperFunction( self.baseFunction, *args, **named )

  File "/home/aanjos/.local/lib/python3.8/site-packages/OpenGL/GL/VERSION/GL_2_0.py", line 469, in glVertexAttribPointer
    contextdata.setValue( key, array )

  File "/home/aanjos/.local/lib/python3.8/site-packages/OpenGL/contextdata.py", line 58, in setValue
    context = getContext( context )

  File "/home/aanjos/.local/lib/python3.8/site-packages/OpenGL/contextdata.py", line 40, in getContext
    raise error.Error(Error: Attempt to retrieve context when no valid context

Everything was working on Ubuntu 20.04. I’ve installed Debian testing today because it has the Linux kernel 5.5 and I got this problem.

I have libgfw3-wayland 3.3.2-1.

Thanks, António

I was already discussing this on the pyOpenGL mailinglist:
https://sourceforge.net/p/pyopengl/mailman/pyopengl-users/thread/M5HjopY--3-2%40tutanota.com/

I think I might file a bug report with them, with that solution you just wrote.

Yes, it could be fixed in pyGLFW with something like this:

 if "wayland" in os.getenv("XDG_SESSION_TYPE", "").lower() and not os.environ.get("PYOPENGL_PLATFORM", ""):
    os.environ["PYOPENGL_PLATFORM"] = "egl"

However I would strongly prefer if this is actually fixed in PyOpenGL as opposed to here, as it has nothing to do with pyGLFW specifically and very, very little with GLFW in general. As far as I am aware, EGL is the OpenGL context creation API for Wayland, so using it as default for Wayland sessions seems generally reasonable when GLX is the only real alternative.
