How to Install Barrier on Ubuntu 20.04 | 22.04 LTS

In this guide, we will illustrate how to install Barrier on Ubuntu systems.

Barrier is software that mimics the functionality of a KVM switch, which historically would allow you to use a single keyboard and mouse to control multiple computers by physically turning a dial on the box to switch the machine you’re controlling at any given moment. Also, it does this in software, allowing you to tell it which machine to control by moving your mouse to the edge of the screen, or by using a keypress to switch focus to a different system.

Barrier was forked from Symless’s Synergy 1.9 codebase. Synergy was a commercialized reimplementation of the original CosmoSynergy written by Chris Schoeneman.

At the moment, barrier is not compatible with synergy. Barrier needs to be installed on all machines that will share keyboard and mouse.
