You don't need to do all this procedure, just press "e" when on ubuntu boot menu (can be the live installation media) and add nouveau.modeset=0 to your kernel options. It is this open source reverse engineered drives that causes all sort of trouble.

You don't need to update kernel to 4.19, it works perfectly fine with 4.18 that comes with ubuntu 18.10 as well. After installing ubuntu, again on boot screen ensure to disable nouveau and if you wish later you can install nvidia proprietary drives inside ubuntu using the update manager

Hello. Can some one help me with instruction? Who can explain me what means "Run this from the Live USB." ? I should run this when Ubuntu is already installed? And where I can change this "root_partition=/dev/nvm0n1p2" ?
Thank you!
