Awesome! Thanks! I've posted your information on the vpython.org Linux download page.

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. >> >> --John >> >> John Zelle, PhD >> Professor of Computer Science >> Wartburg College > > ------------------------------------------------------------------------------ > Live Security Virtual Conference > Exclusive live event will cover all the ways today's security and > threat landscape has changed and how IT managers can respond.
