I'm using a notebook with both Intel and Nvidia GPUs. I correctly installed nvidia-331 drivers, cuda and bumblebee and I can correctly run optirun some_application. Indeed, while some application is opened with the optirun command, the nvidia GPU works correctly

sudo lshw -c video | grep driver
       configuration: driver=nvidia latency=0
       configuration: driver=i915 latency=0

However, I'm searching for a way to automatically enable GPU while launching VirtualBox machines (expecially those created by Genymotion). More generally, I'm searching for a way to automatically start the GPU if the Intel integrated GPU get stressed. Is it possible? What about nvidia-prime?

EDIT: this is what I have installed so far

EDIT2: so far the only way to use Nvidia GPU with genymotion (at least for me) is by launching

optirun <genymotion-folder>/player --vm-name "X"

where X is the name of your virtual machine.

Something similar to the original request can be found in the nvidia-prime project. However, after some tests, I decided to get back to optirun. The main reason is that prime keep your nvidia GPU always on, with a lot more power consumption.
