interpreter stops responding on window creation

[GoogleCodeExporter]

Have you tried Pyglet 1.2 alpha1 or the repository code?
yes

What steps will reproduce the problem?
1. run:
import pyglet

print "window"
window = pyglet.window.Window()

print "run"
pyglet.app.run()

Paste in the traceback or error message:
The program prints "window" than the interpreter stops responding.
The process result as "sleeping" and I have to close the terminal to stop it.

Paste in the output of `python -m pyglet.info`:

Any additional info (platform/language/hardware) that may be relevant?
I am on Debian Testing.
Yesterday everything worked fine.
Googling I found someone that seems to have my same problem here:

EDIT:
the problem is in window/xlib/__init__.py at line 418:
xlib.XNextEvent(self._x_display, e)
doesn't return

I can't reproduce the problem here (Linux, Python 2.7.5). I get "window" and 
then "run" on the terminal and the app doesn't hang.

I ran this:

import pyglet

print "window"
window = pyglet.window.Window()

print "run"
pyglet.app.run()

print "done"

And it worked fine under both Python 2.7 and 3.4. I got prints of "window" and 
"run", and then the window appeared. When I hit the X in the upper right (or 
escape), the window closed and then "done" printed. This seems like the 
expected behavior. I wonder if there are some differences between my system 
(Ubuntu 14.04) and Debian testing...?

Now I'm on an other system, a fresh install of Debian testing, (almost 
identical, on the same pc) and everything works fine; but on the old one it 
still does not work...

[GoogleCodeExporter]

Are both systems up to date? I'm wondering if some bug in another package like 
xorg might have been fixed in your new system. I'm not really sure what the 
best way to diagnose the problem is. I assume both installs are using the same 
set of graphics drivers, too...? Maybe one of the Pyglet devs has some idea (I 
am just a user).

Original comment by larson.e...@gmail.com on 7 May 2014 at 8:19

[GoogleCodeExporter]

The one causing trouble, can you reinstall pyglet in case you installed it?

I'm a little bit lost here as I can't reproduce the issue.

[GoogleCodeExporter]

Rebooted to the old system, and without upgrade anything for days now works on 
both systems... I'll try to upgrade and change configuration of nvidia/intel 
drivers... (I'm on an nvidia-optimus notebook)

Cool! I'm glad it works :)

I'm going to close the ticket, but please feel free to add any other 
information you find or even re-open it if you think there's an actual issue!
