[Visualpython-users] Core Dump on Fedora 13

[Seth M. <sm...@ps...>]

Hello,

I am using Fedora 13 (x86_64).  I previously used visual python on 
Fedora 11, but I cannot get it to work on fc13.  When I try to run 
anything that uses visual, I get this error:

Segmentation fault (core dumped)

The window pops up for a split second (I can't see what's on it, but I 
can see that it is drawn).  I checked, and using only the line from 
visual import * does not cause a segfault, but including

from visual import *
sphere()

does.

Previously, on fc11, I had troubles when using a third-party kmod-nvidia 
(it said there was an OpenGL error), so I had to use the driver directly 
from nVidia.  Now, on fc13, I am again using the kmod-nvidia (I couldn't 
get nVidia's driver to work), but I am getting a different, and much 
less helpful, error message than from before.  My advisor also is using 
fc13, but without the kmod-nvidia driver, and he is getting vpython to 
work, but it is slow and choppy since he has no 3D graphics support.  
We'd like to be able to use both vpython /and/ 3D graphics.

Of course, the driver may be just a red herring, but it's the best lead 
I have.

Does anyone have any ideas?
