This could be a problem, where does that package come from? Looks like
it was built on Ubuntu, but neither the official repository nor
xorg-edgers seem to provide 352.39.

Also this package is from that revision:

libcuda1-352             352.39-0ubuntu1

Please install the versions from the Debian repository and try again.

That should not be an issue. I myself am running 352.30 with
nvidia-xconfig 340.46. I'll have a peek inside the packages later to
confirm, but I'm quite sure.

The new 352.41 is lined up for release, but it doesn't look like from
the changelog that it will make any difference for your GPU, the 980.

Kind regards,
