Black Screen on boot after Nvidia Driver Installation

How do I check? Post on the specs here

I’m using optimus-switcher using the directions laid out here . Haven’t been able to confirm that it was installed properly.

I’ll poke around and see what I find.

I removed that when I installed the Optimus Switch, and it was remade by the Optimus Switcher install. Shall I re-do that step?

I’ll try your step with running i3 directly from .xinitrc
