[SOLVED] intermittent nvidia/pyglet 'GL context' error

Hi all,

I'm having a problem with the Python package 'pyglet' that seems to be related to the nvidia drivers. Importing 'pyglet.gl' gives the following:

Traceback (most recent call last):
  File "<string>", line 1, in <module>
  File "/home/damien/venv/pyglet_test/lib/python2.7/site-packages/pyglet/gl/__init__.py", line 236, in <module>
    import pyglet.window
  File "/home/damien/venv/pyglet_test/lib/python2.7/site-packages/pyglet/window/__init__.py", line 1817, in <module>
    gl._create_shadow_window()
  File "/home/damien/venv/pyglet_test/lib/python2.7/site-packages/pyglet/gl/__init__.py", line 205, in _create_shadow_window
    _shadow_window = Window(width=1, height=1, visible=False)
  File "/home/damien/venv/pyglet_test/lib/python2.7/site-packages/pyglet/window/xlib/__init__.py", line 166, in __init__
    super(XlibWindow, self).__init__(*args, **kwargs)
  File "/home/damien/venv/pyglet_test/lib/python2.7/site-packages/pyglet/window/__init__.py", line 516, in __init__
    context = config.create_context(gl.current_context)
  File "/home/damien/venv/pyglet_test/lib/python2.7/site-packages/pyglet/gl/xlib.py", line 186, in create_context
    return XlibContextARB(self, share)
  File "/home/damien/venv/pyglet_test/lib/python2.7/site-packages/pyglet/gl/xlib.py", line 300, in __init__
    super(XlibContext13, self).__init__(config, share)
  File "/home/damien/venv/pyglet_test/lib/python2.7/site-packages/pyglet/gl/xlib.py", line 203, in __init__
    raise gl.ContextException('Could not create GL context') 
pyglet.gl.ContextException: Could not create GL context

It doesn't happen every time, though - seems to be about 50% (but not in any discernable sequence). It occurs across multiple computers with the same Nvidia card, but not on my laptop with an (older) ATI card.

My video card is 'NVIDIA Corporation GK107 [GeForce GTX 650] (rev a1)', and my version of 'nvidia' is '352.21-2', and my version of pyglet is '1.2.3' (installed via pip).

Does anyone have any ideas on what might be going on, or how to get more information on the error?

Thanks!
