Using x2x to connect two computers and their screens with one mouse and keyboard

Let's say you have 2 computers:

cpu1: 10.0.0.1
cpu2: 10.0.0.2

Let's say cpu1's screen is left to cpu2's screen.

Let's say you want to control cpu1 from cpu2.

Let's assume both computers have the same username.

1. install x2x on cpu1
2. enter on cpu2

ssh -X user@cpu1 'x2x -west -to :0'

and leave terminal open.

And that's it!
