EDIT 5/4/22: Partial solution in the second post!
Notebook:
Razer Blade 15 Advanced Model (Early 2020) - RZ09-033/CH551
Linux version 5.13.0-39-generic
NVIDIA GeForce RTX 2080 Super
Intel(R) Core™ i7-10875H
I was trying to solve a black flickering problem (similar to Ubuntu 20.04 and RTX A2000 (Lenovo P1 Gen4) screen glitches/offset) with Ubuntu 20.04 while I decided to make a clean OS reinstall.
Unfortunately I cannot boot it properly anymore, but using prime-select intel.
I tried several approaches during last hours without success.
After the boot screen, I get a one-second prompt and then the screen turns black. I can’t change any tty then.
Recovery mode works without GUI.

Hi all;
I figured out that I shouldn’t have commented out 61-gdm.rules and custom.conf since NVIDIA and Wayland are not working with Ubuntu 20.04.
Something misled me though: with Wayland disabled, I still couldn’t boot properly since I was getting a blinking prompt instead of the login screen. However, I could change tty from 1 to 2, getting a working shell.
There, I found why Xorg failed booting:

Apparently it’s a known Xorg-server bug, but this comment could fix it enabling Wayland.
Then I tried this last comment. I got a black screen once back to tty1; I was about to give up when I tried to play with the brightness keys. It worked! Apparently the login screen was loaded but for unknown reasons, the brightness was set to 0.
Setting it by +1, the brightness turned to 100 (From 0?) and I could login.
I attach the new nvidia-bug-report if anyone needs it.
