I have a laptop (Dell XPS 15) with nVidia Optimus. It already works: basically the only need I had to install was bumblebee. Most distros will have a package to wrap the needed configuration.

Don't mirror windows, for example in Ubuntu you can use the display configuration gui: Make sure your window settings DO NOT have: Mirror Display (Note: may limit resolution options) checked, as in:

I just 'fixed' it myself, actually. All I did was follow the install guide for the Nouveau drivers and it fixed itself. Here is where I found this.
