The Problem
So, this was my first time doing this. I prepared the bootable pendrive, followed the steps of installation and saw everything working fine using the preview feature, with the correct resolution: 1920x1080. The problem is: after i properly installed Ubuntu and rebooted my PC, the screen resolution dropped to 640x480 and the options to change that back are not available in the configs.
I’ve attempted finding a solution on my own, but everything I tried to do didn’t work and/or made things worse, to the point where it would not boot and I had to reinstall it. I decided, then, to look for help and ask a question here.
Thanks in advance!

- Edit_1: also couldn't solve it for me. It does not seem to be what is causing my problem, since my

Ok, i found a solution to this problem of mine!
Here:
I just followed the tutorial and installed the nvidia-driver-390 by cmd, since i was not able to change it in "Additional Drivers". Once i rebooted the system, it started in 1920x1080 and many others are now available at display settings.
Thanks to those who tried to help.
