In this video I cover how to set up Ubuntu for gaming so that you can play both Windows and Linux developed games. Step 1. Install Steam & Enable Proton Install Steam using your distribution’s package manager either with a GUI software store, or with the following Terminal command. sudo apt install steam https://store.steampowered.com/about/download Alternatively if you get a message about missing dependencies, then download and run the installer from the Steam website instead. In either case, once installed, launch the application and sign into your account. Next, enable Proton for your entire library by navigating to Steam / Steam Play / Advanced and ticking the Enable Steam Play for all other titles. This will choose Proton Experimental as the default Proton build is what you usually use for 99% of games. Restart Steam to apply the settings. https://github.com/GloriousEggroll/proton-ge-custom#proton-ge-custom Sometimes, specific game fixes that have not been included in the official Proton builds can be included in a custom build of Proton, and one of the most popular version available is Proton-GE. To install and use Proton-GE, navigate to the Releases page and download the latest version. Extract the archive, and make a copy of the Proton-GE folder. Next open your home directory enable Hidden Files, navigate to. steam / root, create a new folder called compatibilitytools.d and paste the Proton-GE folder inside. Restart Steam to apply. Now when you right click on the Properties of a game, under the COMPATIBILITY tab, you can now select the build of Proton-GE from the list. Step 2. Install Lutris Whilst using Steam with Proton will cover games that available in the Steam ecosystem, it is recommended to use Lutris to install and run games available on other platforms such as EA Origin, Blizzard Battle.net or Uplay. https://lutris.net/ From Ubuntu 21.04, Lutris can be installed from the distribution repository using a package manager with a GUI software store or the following terminal command. sudo apt install lutris The interface for Lutris is straightforward, simply click on the + button located at the top of the application, search for the game you wish to install and follow the instructions from there. Step 3. Install Feral Gamemode https://github.com/FeralInteractive/gamemode#gamemode Feral Gamemode is a daemon that applies several performance tweaks when it is is launched with full screen applications such as video games. Feral Gamemode has been pre-installed since Ubuntu 20.04, but you can reinstall it using the below Terminal command. sudo apt install gamemode Once installed, you just need to request it. In Steam, adding gamemoderun %command% into a game’s launch properties is enough. And in Lutris, assuming that Gamemode is installed, it should be enabled by default. If not, you can find the toggle in Preferences / System Options. #ubuntu #linuxgaming #proton
