Pretty sure this was in F12.

Depends on your laptop. There seem to be two major varieties. One is where there's a BIOS option and you can pick. Your options will typically be "integrated" (where we'll pick intel), "discrete" (where we'll pick nouveau), or "OS switchable" (where you'll see both in lspci, but the intel one will be the one that powers up on boot, so we'll pick that one and power down the nv chip). The other is where there isn't a BIOS option, which acts like "OS switchable". - ajax
