lately I was searching for a graphic library to use with python. While testing panda3d and pyglet I could not even run the examples. I don't exactly know if this is due to the same problem, but it seems to me that is has a common issue. Unfortunately I'm not experienced enough to solve this issue and therefore need some help.

I got the following errors:

pyglet:

Speicherzugriffsfehler (Speicherabzug geschrieben)

running this code:

from pyglet import window
window = window.Window

panda3d:

Starting the game.

Abgebrochen (Speicherabzug geschrieben)

running the Asteroids example.

(I am using Ubuntu 12.04 and python 2.7.3.)

Info: "Speicherzugriffsfehler (Speicherabzug geschrieben)" roughly means "memory-access-error (core dumped)"

Thanks for your help, Max

P.S.: Every other post I found regarding this topic was about C/C++ mostly having problems with pointers / direct memory access. Since I am only using basic examples something must be wrong with the libraries - which I doubt - or I have a wrong package configuration somewhere / a broken driver. Another option would be a problem with the window creation itself which I unfortunately don't know enough about either. Please tell me if I need to post more information.

在我意识到其他一些程序（例如搅拌机）也停止运行后，我重新安装了 amd 驱动程序，现在一切正常。
