Solution for Ubuntu 18.04 Login Loop or Desktop Freeze after Nvidia Driver Installation

After the installation of ubuntu 18.04, I get trapped in a login loop. Then I found a solution online:

sudo add-apt-repository ppa:bumblebee/stable
sudo apt-get update
sudo apt-get install bumblebee bumblebee-nvidia

Voila! I logged in, and I found that the keyboard and mouse is unusable after logging in.

This is the solution to solve this: 

sudo apt install xserver-xorg-input-all
