I've seen some posts announcing native Nvidia Optimus support since 14.04. But I've also found many tutorials of how to install and run bumblebee on this very same distribution.
So my question is... is bumblebee still required in order to properly use and alternate between my laptop's discrete and dedicated graphics cards or I should expect them to work as intended out-of-the-box?
What exactly do they mean by "native support"?
