The point about Bumblebee

Question

As I assume, Bumblebee can automatically switch between graphic cards and you can force an application to use exact GPU (though you don't have to). The switch is to save power (as nVidia GPU is stronger but consumes more power).

Am I right?

From the FAQ:

I have a laptop with Nvidia card and an integrated graphics card, how can Bumblebee help me?

By disabling the nvidia card, power is saved. This improves battery life. If you need more graphical performance, Bumblebee can run the program using the Nvidia card.

So, yes.

This happens when you run the desired app with "optirun" or "primus" in front of it.

Example: optirun glxinfo
