Lutris is an open source gaming platform for Linux. It makes gaming on Linux easier by managing, installing and providing optimal settings for games.

Lutris does not sell games - the user needs to provide copies of the games unless they are open source or freeware. Games can be installed anywhere on the system, Lutris does not impose anything.


Install Lutris:

root #emerge --ask games-util/lutris

Multilib dependencies

Many games require a working multilib system, this includes some abi_x86_32 vulkan loader libraries. Even if Lutris doesn't complain about these missing libraries, it's always a good idea to add their respective multilib variants in your package.use, as well emerging the abi_x86_32 variant of net-libs/gnutls and libsdl2, otherwise, errors or launch problems in some particular games will occur.

Add these USE flags into your package.use file:

FILE /etc/portage/package.use
#Lutris multilib dependencies
media-libs/vulkan-loader abi_x86_32
media-libs/vulkan-layers abi_x86_32
media-libs/freetype abi_x86_32
media-libs/libpng abi_x86_32
net-libs/gnutls abi_x86_32
media-libs/libsdl2 abi_x86_32

Once the required multilib dependencies are added into the package.use file, update the system:

root #emerge --ask --changed-use --deep @world


Lutris relies on programs known as 'runners' to provide a vast library of games. These runners (with the exception of Steam and web browsers) are provided by Lutris, and don't need to be installed by the system package manager. Refer to the Lutris website for a list of currently supported runners.

Installer scripts

Lutris automates installation of games using configuration scripts written in JSON or YAML, which list the various files needed to install a game and can perform a series of actions on them. The syntax of installers is described docs/installers.rst on Github, and is also available on when writing installers.

A web UI is planned to ease the creation of these scripts.

Game library

Users can optionally create an account on and connect their account to the client. This will allow the user to sync their game library from the website to the client (not the other way around). The user can also sync their Steam library with the Lutris library on the website.

The client does not store credentials on the system. Instead, when a user authenticates, the website will send a token which will be used to sync the library. This token is stored in ~/.cache/lutris/auth-token.

Configuration files

The client, runner, and game configuration files are stored in ~/.config/lutris. There is no need to manually edit these files as everything should be done from the client.

  • lutris.conf: preferences for the client's UI
  • system.yml: default configuration for every game
  • runners/*.yml: runner-specific default configurations
  • games/*.yml: game-specific configurations

The game configuration can override previously defined runner and system configuration and runner configuration can override system configuration.

Runners and the game database

The data necessary to manage the game library and run games is stored in ~/.local/share/lutris.

  • pga.db: game library, game installation status, locations on the file system, and some additional metadata, all stored in an SQLite database
  • runners/*: runners downloaded from
  • icons/*.png and banners/*.jpg: game images

Command line options

The following command line arguments are available:

user $lutris --help
  lutris [OPTION…] URI

Run a game directly by adding the parameter lutris:rungame/game-identifier.
If several games share the same identifier you can use the numerical ID (displayed when running lutris --list-games) and add lutris:rungameid/numerical-id.
To install a game, add lutris:install/game-identifier.

Help Options:
  -h, --help                 Show help options
  --help-all                 Show all help options
  --help-gapplication        Show GApplication options
  --help-gtk                 Show GTK+ Options

Application Options:
  -v, --version              Print the version of Lutris and exit
  -d, --debug                Show debug messages
  -i, --install              Install a game from a yml file
  -e, --exec                 Execute a program with the lutris runtime
  -l, --list-games           List all games in database
  -o, --installed            Only list installed games
  -s, --list-steam-games     List available Steam games
  --list-steam-folders       List all known Steam library folders
  -j, --json                 Display the list of games in JSON format
  --reinstall                Reinstall game
  --display=DISPLAY          X display to use

Additionally, a protocol link (lutris:) followed by a game identifier can be passed on the command line:

user $lutris lutris:quake

This will install the game if not already installed or launch the game otherwise (unless the --reinstall option is passed).

Managing libraries

If the Lutris runtime is disabled (Lutris->Preferences->System options->Disable Lutris Runtime), then Lutris will use system the libraries, otherwise it will use the libraries in ~/.local/share/lutris/runtime/lib*.

Locating missing libraries

One way of locating missing libraries is to use e-file command which is part of app-portage/pfl.

user $e-file <file>

Where <file> is the full name of a file (supports wildcards) that is being located.

About missing libraries

Gentoo may require additional dependencies for Lutris games to work out of the box. Those libraries won't be included in Lutris and need to be added manually.

Sent reports to


Lutris is using watchers:

DEBUG    2018-10-07 09:23:49,284 [steam]:Watching Steam folder /home/$USER/.steam/steam/steamapps

To detect games in the native Steam library and add them to the Lutris library if enabled.


Lutris outputs to stderr and stdout seemingly at random.

The most effective way to debug Lutris and its runners is to invoke lutris -d in terminal with unlimited scroll.

Using lutris -d 2>&1 lutris.txt is also recommended.

Planned features

Here's what to expect from the future versions of Lutris:

  • Integration with GOG and Humble Bundle
  • Integration with the TOSEC database
  • Management of Personal Game Archives (will allow storing game files on private storage so that they can be re-installed on other devices)
  • Game saves sync
  • Community features (friends list, chat, multiplayer game scheduling)
  • Controller configuration GUI (with xboxdrv support)

Where to look for help


Wine cannot find winemenubuilder.exe


winemenubuilder.exe is used in Wine to make Linux menu shortcut from Windows.

wine: cannot find L"C:\\windows\\system32\\winemenubuilder.exe"

This should be ignored, because Lutris is going to make its own shortcuts at the end of each installation.

Possible solution:

To remove this error message from Wine console:

Lutris->Manage runners->Wine->Configure runner->DLL overrrides->Key=winemenubuilder.exe
Lutris->Manage runners->Wine->Configure runner->DLL overrrides->Value=d

This will disable winemenubuilder.exe. Value can be set to b to enable winemenubuilder.exe which is not recommended for the reasons stated above.

Wine cannot find FreeType font library

FreeType is written in C, designed to be small, efficient, highly customizable, and portable while capable of producing high-quality output (glyph images) of most vector and bitmap font formats.


Wine cannot find the FreeType font library.  To enable Wine to
use TrueType fonts please install a version of FreeType greater than
or equal to 2.0.5.


a) Emerging media-libs/freetype

b) Installing libfreetype2 library to the location that is set for a process that needs it.

c) Installing library to the Lutris runtime.

Wine version mismatch


wine client error:0: version mismatch 549/566.


a) This issue was resolved in Lutris 0.4.19+.

b) Invoke pkill wine && pkill wineserver. There is a bug which results in Wine mismatch if the Wine version is changed.

No DirectX 10 or 11 adapter or runtime found


ERR_GFX_D3D_NOD3D1X_4 - No DirectX 10 or 11 adapter or runtime found. Please install latest DirectX runtime or install a compatible DirectX 10 or 11 video card.


a) Vulkan and/or DXVK is not configured properly. Check vulkaninfo.

b) The Wine application needs DirectX libraries. Use Winetricks to install them.

c) Lutris is missing libraries in its runtime (~/.local/share/lutris/runtime/lib*).

SESSION_MANAGER environment variable not defined


Failed to connect to session manager: Failed to connect to the session manager: SESSION_MANAGER environment variable not defined


Was resolved by restarting Lutris (xkill && lutris)

BadWindow (invalid Window parameter)

This problem seems to appear when virtual Wine window is xkill-ed.


X Error of failed request:  BadWindow (invalid Window parameter)


Solved by invoking pkill wine
