Visual Python doesn't show anything

Hi, i'm Daniel and i'm trying to run a vpython on GNU Linux Debian Wheezy
(testing by now) with kernel 3.2.0-amd64 with an nVidia 9400 GT Graphics
card. i have tested the Vpython on Windows and it works with excellent
performance, but when i try to use it on Linux it just run but doesn't show
anything
 This is the typical prompt

Python 2.6.7 (r267:88850, Aug  3 2011, 11:33:52)
[GCC 4.6.1] on linux2
Type "copyright", "credits" or "license()" for more information.
