I don't have Optimus as my laptop is old.
Optimus goes back 10 years, but I don't know if it was used with removable graphics cards. In any case, if you want to run everything using the graphics card you are in the same pickle I had when the software controlled switch failed in my 2010 Macbook Pro. In that case, I did a text mode install and then install the (Nvidia) drivers for the discrete graphics to get around the GUI installer's attempts to use bumblebee (linux optimus support).
