Re: [Visualpython-users] Core Dump on Fedora 13

Seth,

I have vpython running on Fedora 13 with Intel based video cards with 3d support.  So, I'm guessing your problem comes from the 3rd party packaged nvidia driver.

I've installed the nvidia's driver successfully on fedora 13 at home.  It's been a while, so I don't remember what exactly I did, but I remember the biggest problem was making sure the open source nvidia driver was prevented from loading at startup.  What exact problem did you run into with the official nvidia driver install?

It seems to be the same crash like:

But I have no idea how to track this down...

The standard F12 method was to stop the open source driver loading
with this put in the /boot/grub/grub.conf file
on the kernel line....    rdblacklist=nouveau

There was another method if you switched between the drivers but
this was the easiest.

I have definitely isolated the problem to the installation of 
kmod-nvidia from the RPMFusion repository.  On a computer in which we 
have VPython running, installing kmod-nvidia causes VPython to crash.

Jason, to answer your question, I ran into problems in the install phase 
of the driver from NVIDIA ('NVIDIA-Linux-x86_64-256.35.run').  I don't 
recall the actual error message, however.  I have no problems preventing 
the open source driver from loading (since I have to do that for 
kmod-nvidia as well).

The reason why I would like to avoid using the NVIDIA driver is that 
when yum issues a kernel update, my computer crashes on reboot and I 
have to reinstall my OS... it seems to mess with some things that 
prevent a new kernel from booting.  In fact, the NVIDIA website actually 
says that using the kmod-nvidia is safer since it is designed not to 
mess with things it shouldn't: ''' Note that many Linux distributions 
provide their own packages of the NVIDIA Linux Graphics Driver in the 
distribution's native package management format. This may interact 
better with the rest of your distribution's framework, and you may want 
to use this rather than NVIDIA's official package.'''

I guess my question is why would one version of the driver cause VPython 
and another not?  Or, is there a way to install the NVIDIA driver 
without having it mess with my kernel updates?  I realize those aren't 
really VPython questions, but hopefully one of these answers may allow 
me to get VPython working again.
