PlayOnLinux is a graphical front end interface for Wine. And if you don't know already, Wine is popular software that allows many Windows applications to run on a Linux system. The problem with Wine is that you sometimes have to do quite a bit of configuration to get a particular application to run; we even have quite a few guides about it on this site.

PlayOnLinux basically hides the complexity of Wine to the user, giving you a graphical interface to work with and automating the installation of many popular applications. Contrast this with just using Wine itself, where you'd inevitably be working with the command line more and have to fiddle around with configuration settings to get stuff working right.

In this guide, we'll show you how to install PlayOnLinux on Ubuntu 20.04 Focal Fossa, as well as go through a rundown of how to install some games and software that you'd ordinarily only find available on Windows.

  • How to install PlayOnLinux with command line or GUI
  • How to install an app or game within PlayOnLinux

Lutris is a game manager built for Linux operating systems, and it does its job incredibly well. It has thousands of games in its catalog and works with very little fuss, allowing you to install games from the cloud and keep them up to date. Most games are "one click install" titles, meaning that you shouldn't have to worry about fiddling with extra configuration to get a Windows game working on Linux. It just works.

Lutris requires Wine in order to ensure a smooth experience. The two work really well together, and that's because the developers of Lutris also work directly with Wine staging. Since the Lutris developers already program their installers to use the most optimal settings possible, there's no need to fool around with Winetricks or any of the usual Wine configuration utilities.

If you want to run Ubuntu 20.04 Focal Fossa on your system but you already have Windows 10 installed and don't want to give it up completely, you have a couple of options. One option is to run Ubuntu inside of a virtual machine on Windows 10, and the other option is to create a dual boot system. Both options have their pros and cons. A big advantage of a dual boot system is that both operating systems will have direct access to your computer's hardware - no virtualized hardware and unnecessary overhead.

A dual boot system gives you the best of both worlds. It works by prompting you at startup to select which operating system you'd like to load into. So, you'll have to reboot your computer each time you want to load into a different operating system. Make sure you consider this before deciding to proceed with the dual boot option.
