Won't login, resolution off, screen flickers

Question

So, since last restart my Ubuntu won't log in, it just loops.

Here's a video of what happens: https://youtu.be/XS4j4M8HLCM

Ive tried to follow a few tutorials and solutions like making a new Xauthority file but so far no luck.

Also, the resolution is weird.

Please help, Thanks.

I have had the same issue in the past. I recommend installing and using GDM. You can do this by typing

sudo apt install gdm3

Logout and choose gdm. Tell me if this fixes your issue too. Or type

sudo dpkg-reconfigure gdm

and then choose gdm3.
