Re: [Visualpython-users] seg faulting (SOLVED)

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

Hi All,

I think we have tracked down the problem with Vpython seg faulting on 64 bit Ubuntu with NVIDIA drivers. It appears that some packages install a minor version upgrade of some glx libraries that cause the breakage. The following command restores a working VPython for us:

sudo apt-get install libgl1-mesa-glx=8.0.2-0ubuntu3 libglapi-mesa=8.0.2-0ubuntu3

This reverts from the 8.0.3 version of these packages down to the 8.0.2 that was the original install and that the stock NVIDIA drivers are apparently built against.

So we now have Vpython working on 64-bit Ubuntu using both the stock NVIDIA drivers and python-visual that come with Ubuntu.

I guess this proves that my experience with the Boost libraries is
irrelevant. Thanks for this further analysis.

John,

That fix works for me! Wonderful! If I ever find myself in Iowa, I owe you
dinner.

+1.  That fix worked for me.  Although I didn't have nvidia installed, but
I did have it installed previously.

Thanks so much! :D

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

Awesome!

As said before, this is something that should be communicated upstream
to the package maintainers. They've got some leverage to get the
dependencies right.

Re: [Visualpython-users] seg faulting (SOLVED)

[Guy K. K. <guy...@au...>]

I have added information to the existing bug on launchpad for the
python-visual package. Let's hope that the maintainer knows what to do
in order to escalate it to the right instances to get it resolved for
the future. Also, if you're on Ubuntu and have got the problem, you may
want to mark yourself as being affected in order to increase the
priority of the bug, and improve chances of somebody working on it.

Also, if you do have further insights, a further confirmation, or other
conditions under which it occurs, please also specify those in an
additional comment.

https://bugs.launchpad.net/ubuntu/+source/python-visual/+bug/787932

Thanks,

Guy

Helps just as well on some 32 bit systems with NVIDIA drivers here.

Cool!
