Thanks for the reply. The thing is I had not installed the drivers
manually, I've been always using the urpmi tools to install and update
as much as possible (including the kernel and nvidia drivers).

At the end that's what I had to do. I tried uninstalling and installing
the distribution's rpm packages, with no luck. So I downloaded the
latest nvidia driver and installed it manually (after installing the
rmp's, since there was a conflict). Now it's working fine again,
including the "broken" volume isosurface files, but I still don't know
what was the reason for this sudden (in my view) fail. (The kernel
update/reboot I mentioned was only done after the problem appeared.)

Thanks again,
Ignacio
