Comment 82 for bug 1812359

Okay thanks,

Here I found something new in Ubuntu 18.04.2,
I thought about to install kernel 4.15.0-43, login screen appeared but resolution issue and not network adapter, neither ethernet nor wireless, so just leave it

Then for kernel 4.15.0-45-generic, I've disabled wayland
During booting, ubuntu logo appeared (seems like when we set nomodeset), then splash divided into two(ubuntu logo left and right side) and after a minute login screen appeared,

but after login, just a wallpaper and nothing like it's freezing, same issue.

Please check a log if you can find something new.
