pyglet.window.NoSuchConfigException: No standard config is available

[Federico Cáceres]

Hi, I just downloaded and installed Pyglet 1.1.3 using setup.py on a
Fedora 11 x86_64 with KDE 4.3.0 as desktop environment with python
2.6.

I tried to run several of the demo files but always got an error when
launching the script. For instance, for the following script:
import pyglet
window = pyglet.window.Window()

I get this error:
Traceback (most recent call last):
File "example.py", line 2, in <module>
window = pyglet.window.Window(config=config)
File "/usr/lib/python2.6/site-packages/pyglet/__init__.py", line

line 643, in __init__
raise NoSuchConfigException('No standard config is available.')
pyglet.window.NoSuchConfigException: No standard config is available.


I would greatly appreciate if someone could point me out on what I
could do to get Pyglet working on my computer.

By the way, I have a NVIDIA 8600 GT and I am currently using NVIDIA's
propietary drivers, version: 185.18.14.

Cheers,
Federico

Ok, so I continued my adventures with Pyglet...

First of all, I cannot even run gl_info.py on my machine... it gives me the same error...

I have a  Ubuntu 9.04 (i386 version) virual machine with my Fedora 11 x86_64 running as Guest, and Pyglet ran just fine (sluggish, but at least it ran) on that machine... that made me become very mad!

So today I started debugging pyglet's code for my simple code:
    # -*- coding: utf-8 -*-
    import pyglet
    pyglet.options['shadow_window'] = False
    #pyglet.window.get_platform().get_default_display().get_default_screen().get_best_config()
    window = pyglet.window.Window()
 
I started tracing the source code (using pdb) starting just before the "window = pyglet.window.Window()" line on my code.
After slowly inspecting the code (and skipping other parts that I didn't care for) I got to this lines in the /usr/lib/python2.6/site-packages/pyglet/window/xlib/__init__py file (from line line 265):
        if have_13:
            elements = c_int()
            configs = glx.glXChooseFBConfig(x_display, self._x_screen_id,
                attrib_list, byref(elements))
            if not configs:
                return []
When printing the value of configs I get:
<pyglet.gl.glx.LP_LP_struct___GLXFBConfigRec object at 0x16dc050>

But I saw that the debugger evaluated the "if not configs" line and then returned []!
So, before the debugger returned from this level, I wrote this in the pdb prompt:
(Pdb) not configs
And it printed "True" as a result!

What?! Inspected the config variable and then printed the only "normal" attribute, "contents". printing configs.contents gave me the following:
*** ValueError: NULL pointer access

I think my error can be here... I don't have a clear idea on what I can do next... whether this is a 64 bit issue or... a missing library... let me paste the values of other maybe relevant variables in the local context:
attrs = [5, 1, 12, 24, 32786, True, 0, 0]
attrib_list = <pyglet.window.xlib.c_int_Array_8 object at 0x16dc200>
elements = c_int(0)
x_display = <pyglet.gl.glx.LP_struct__XDisplay object at 0x16e9cb0>
Although all those structs don't look so useful pasted here :D

Further comparisons with my Ubuntu virtualmachine gives me that the self.display.info.get_server_version() returns different strings
'1.4' on Host Fedora
'1.3' on Guest Ubuntu
thus...
have_13 is True on Fedora and False on Ubuntu... so the path that is executed by both machines is different... further comparisons will reveal nothing :(...

So... err... any ideas guys?
Thank you,
Federico

Do you have an ATI card? Ubuntu chokes on a lot of hardware-
accelerated stuff on ATI cards, since Jaunty, which introduced a new
version of X.org, which the ATI restricted drivers are not compatible
with. The ATI open source drivers are fine for desktop use, but
rubbish for game / OpenGL stuff.

Especially medium-to-old ATI cards are affected (eg. my Radeon X1400)
- I assume that open source effort is most enthusiastically focussed
around newer cards for the moment.

You can also try 'glxinfo' to check whether your hardware is present/
accelerated.
If it does not work, you can also try 'sudo glxinfo'

Unfortunately like I said on my second post Pyglet works just fine in a virtualized Ubuntu 9.04 (using virtual box and its 3d acceleration feature). It is the host machine, a Fedora 11 x86_64, that has problems running Pyglet. I would really like to discover what is wrong/missing on my Fedora installation to get this working...

My specs & software:
Cpu: Intel Core 2 Quad Q8200 @ 2.33Ghz
Ram: 4 GB DDR2
GPU: Nvidia 8600GT with 1GB of RAM
GPU Drivers: NVIDIA's propietary drivers, version: 185.18.14
OS: Fedora 11 x86_64
KDE 4.3.0
Python 2.6
