I am trying to set up the Nvidia Driver on Ubuntu 18.04 LTS for my Lenovo Y510P Laptop. My laptop has a Nvidia Optimus Technology graphics card (GeForece GT 750M). I have tried using all of the additional Nvidia Drivers including current to old, 415, 410, 396, 390, and 340 (with ppa:graphics-drivers). I have tried using Bumblebee (which is no longer available using ppa:bumblebee/stable), I have tried changing .conf files, I have tried using bbswitch, Prime and others, but no luck. I either get a black screen with a blinking cursor in the top left corner, or a Login loop.
I have spent 5 days searching this and other forums trying to find a solution, but after trying dozens of different solution attempts, nothing works. Unfortunately, all forum topics I have found up to this point are very outdated and provide old solutions to additional software such as Bumblebee that is no longer available or updated. Please help.
