"Materials will work with graphics cards that support Pixel Shader 3.0
("PS 3.0"). For details, see<br>
<a href="http://en.wikipedia.org/wiki/Pixel_shader#Hardware"
target="_blank">http://en.wikipedia.org/wiki/Pixel_shader#Hardware</a>.
<em>Some</em> materials may work with graphics cards that support PS
2.0, but other materials may need to be manually disabled; see
instructions in the <strong>site-settings.py</strong> module in the
Visual package in your site-packages folder. If the graphics hardware
does not support pixel shaders, the material property is ignored. If
you think you should be able to use materials but have trouble with
their display or performance, we highly recommend upgrading your video
card drivers to the latest version."<br>
<br>
The wikipedia article shows that the Intel GMA X3100 doesn't support PS
3.0, so you might want to modify site-settings.py as explained above.<br>
<br>
Can you run a simple program like bounce2.py, which doesn't involve
material properties?<br>
<br>
Can you be more specific about what is meant by "closing its windows
without being properly required to"? What programs? Do you see a
graphics window and a scene for a while before the crash?<br>

<pre wrap="">I have just installed vpython 5.0, and I get this message any time I run
an example:
VPython WARNING: errors in shader program:
linking with uncompiled shader
My system is:
Ubuntu 8.10 Intrepid Ibex
Video card: Intel GMA X3100
I have the following libraries installed:
libgl1-mesa-dri 7.2
libgl1-mesa-glx 7.2
I can run some of the examples, but they exhibit erroneous behaviour, as
closing its windows without being properly required to.
I am grateful for any help.
