I think that was definitely a portion of the puzzle. I had never selected gallium before, so it never wasn't using the classic driver. Which makes the segfault even more mysterious. I selected gallium for all the options and I now have a hang again (it went away when using - -gallium, forgot to mention that). My updated glxinfo is attached. I think it's odd that glxgears works but not pyglet. It may be like you mentioned, not accepting the software fallback. Oh, and selecting gallium didn't move OpenGL onto hardware, it's still running in software. Could it possibly be a kernel option somewhere? KMS is on and I compiled in Intel DRM support. Just flailing around wildly for causes. - -- Corey Richardson -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.17 (GNU/Linux) Comment: Using GnuPG with Mozilla - iQEcBAEBAgAGBQJNtPiVAAoJEAFAbo/KNFvpg/gH/RtKgBOThCz9hAIdPUeSgz9r QYHp3+FhlJZOp6qgY2u9IddXV5zVZgVL3Jh4YtQjmj1Fjq0m/cN5kQXhUhKwr6bh aUswUla6Yg5Jy3XH6OjpLqVhkQ2cHkpJNpgae3gH/nki0DpFthEULoxLl24I1bHR oBm6DkQM7iEayB5ZAd7tpQm0lVY5/gClUYoFFDpiUyKlAg4CXtv527Rormu+lyM3 NsFk6Efu873moIrLIgBDbCPhUujUXRLmPm93gQZTqt8YYMTxhebAtv0YLa9Y2Mf1 9QLKRZY0sW0cpk7JGz86p/cJirS/GojnfnMxcbWoYN2mdCqH/6+cbsg2l1CSSfE= =mgUV -----END PGP SIGNATURE-----
