On an optimus system the base driver cannot be installed by itself. See
https://wiki.debian.org/Bumblebee

To use the proprietary driver on an optimus system the bumblebee-nvidia
package is needed.

Furthermore, as Nvidia's website states, the minimum driver version for
the 940mx is the 352 series, so the nvidia-driver in jessie is too old.
Make sure to install all the packages from backports:

sudo apt-get install -t jessie-backports bumblebee-nvidia

So closing this as invalid. If you have issues with bumblebee, please
open a separate bug against that package.

Kind regards,
