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).
