Your logs show that you have configured bumblebee to use Nouveau, so
this has nothing to do with the nvidia-driver* packages:

If you want to use the proprietary driver, you need to configure so
in /etc/bumblebee/bumblebee.conf.
Once you do that, please run update-glx --configure glx and select
"bumblebee" to make sure all the links are up to date. If you still have
problems, please report back including the content
of /etc/bumblebee.conf and the output of reportbug --template
nvidia-driver.

That bug report showed in the log a Xorg ABI problem, which is tied to
355, which was already reported in 813565, hence the merge.

There were huge changes in the structure of the drivers which required
extensive changes to packaging. At some point a new version will arrive
in experimental, we are working on it. Please be patient.
