This is the default program for setting nvidia graphic cards is:

If you hava a Nvidia-Prime capable graphic card, you till get the possibility to choose from which grahic card to start upon the next login:

nvidia-settings

  Switching between the graphic subsystems requires logout / login

Bumblebee is almost broken with Ubuntu > 14.04. But with [this|http://nlug.ml1.co.uk/2016/02/an-almost-authoritative-guide-to-nvidia-prime-and-bumblebee/5065] guide I got nvidia prime with bumblebee in Ubuntu 16.04 running. That spoken means, I can run the intel graphics AND can start simultaneously a program like blender with the build-in nvidia graphics card like

vblank_mode=0 primusrun blender

Processor

This will last a little while (at least for me):

- Intel(R) Core(TM) i7-2670QM CPU @ 2.20GHz (4 cores, Hyperthreading, 800-2,2 GHz)
