Re: [Visualpython-users] seg faulting

[John Z. <joh...@wa...>]

Hi All,

Let me second what Guy is saying. I am attempting to run VPython using the stock Ubuntu package (python-visual Ubuntu 12.04, 64 bit), not building it myself.  It works out of the box with a clean install and update of all installed packages. However, it appears that some other package that I install later on breaks VPython. It also appears that the issue is somehow tied to NVIDIA drivers, since I don't have this problem on machines with Intel graphics. Others have reported that the seg fault starts after updating the NVIDIA pacakges for CUDA. I have not done that (yet), so it appears the problem is more general than that. Hopefully, we'll be able to track down the offending packages once I get some lab help back later this week.

I guess the problem is more general, also with others.

I have just tried myself on a 64 bit machine with an NVIDIA adapter and
proprietary drivers, and it crashes as well. It uses the stock packages
from Ubuntu 12.04.
