This page is intended to explain how to run Steam, Steam games as well as proprietary DRM-free games under NixOS. | |||
== Prerequisites == | |||
If you are using 64-bit system and plan to also run 32-bit code (some games are 32-bit only) - add <syntaxhighlight lang="nix" inline>hardware.opengl.driSupport32Bit = true</syntaxhighlight> and <syntaxhighlight lang="nix" inline>hardware.pulseaudio.support32Bit = true</syntaxhighlight> (in case you are using pulseaudio) to your configuration. | |||
== | Example snippet of <code>configuration.nix</code>: | ||
<syntaxHighlight lang=nix> | |||
... | |||
hardware.opengl.driSupport32Bit = true; | |||
hardware.pulseaudio.support32Bit = true; | |||
... | |||
</syntaxHighlight> | |||
== Installation == | |||
Several installation options exist. | |||
=== Pure steam client === | |||
If you need Steam client, install it with<syntaxhighlight lang="nix" inline>steam</syntaxhighlight> package. | |||
Example snippet of <code>configuration.nix</code>: | |||
<syntaxHighlight lang=nix> | |||
environment.systemPackages = with pkgs; [ | |||
... | |||
steam | |||
]; | |||
... | |||
</syntaxHighlight> | |||
=== Native steam client === | |||
If you want Steam client to use NixOS libraries instead of Steam-provided, you need to set an override. Note, that this may be broken. | |||
Example snippet of <code>configuration.nix</code>: | |||
<syntaxHighlight lang=nix> | |||
environment.systemPackages = with pkgs; [ | |||
... | |||
(steam.override { nativeOnly = true; }) | |||
]; | |||
... | |||
</syntaxHighlight> | |||
=== FHS environment only (aka GOG/Humble) === | |||
This will only make partial installation - provide the script, which creates the typical environment expected by proprietary games and software on regular Linux, allowing to run such software without patching. Useful if you plan to run GOG or HumbleBundle games. | |||
First option is to install either<syntaxhighlight lang="nix" inline>steam-run</syntaxhighlight> or <syntaxhighlight lang="nix" inline>steam-run-native</syntaxhighlight>. The native version may work better for DRM-free standalone games. | |||
Example snippet of <code>configuration.nix</code>: | |||
<syntaxHighlight lang=nix> | |||
... | |||
environment.systemPackages = with pkgs; [ | |||
... | |||
steam-run-native | |||
]; | |||
... | |||
</syntaxHighlight> | |||
Other option, in case you need more flexibility, is to directly reference to the part of steam metapackage instead. In fact, <code>steam-run-native</code> above is just a wrapper linking to <code>steam.run</code>. | |||
Example snippet of <code>configuration.nix</code>: | |||
<syntaxHighlight lang=nix> | |||
... | |||
environment.systemPackages = with pkgs; [ | |||
... | |||
(steam.override { nativeOnly = true; }).run | |||
]; | |||
... | |||
</syntaxHighlight> | |||
This builds same result as <code>steam-run-native</code> above. | |||
Install the game by setting the executable attribute on the installer and then running it via <code>steam-run ./your_gog_installer.sh</code>. After installation, edit the "~/.local/share/applications/your_game_here.desktop" and replace the exec line from <code>Exec="/home/user/game/start.sh" ""</code> with <code>Exec="steam-run" "/home/user/game/start.sh"</code>. | |||
== Adding missing dependencies == | |||
This is can be done this way: | |||
<syntaxHighlight lang=nix> | |||
... | |||
environment.systemPackages = with pkgs; [ | |||
... | |||
(steam.override { extraPkgs = pkgs: [ mono gtk3 gtk3-x11 libgdiplus zlib ]; nativeOnly = true; }).run | |||
]; | |||
... | |||
</syntaxHighlight> | |||
=== Java === | |||
Example snippet of <code>configuration.nix</code>: | |||
<syntaxHighlight lang=nix> | |||
... | |||
programs.java.enable = true; | |||
environment.systemPackages = with pkgs; [ | |||
... | |||
(steam.override { withJava = true; }) | |||
]; | |||
... | |||
</syntaxHighlight> | |||
You can test java availability by invoking chrooted bash instance: <code>steam-run bash</code> and then typing: <code>java -version</code>. Can be combined with extra packages above. | |||
== Limit user access == | |||
Example snippet of <code>configuration.nix</code>: | |||
<syntaxHighlight lang=nix> | <syntaxHighlight lang=nix> | ||
... | ... | ||
users.users.<your-username>.packages = [ | users.users.<your-username>.packages = [ | ||
pkgs.steam | pkgs.steam | ||
]; | ]; | ||
... | |||
</syntaxHighlight> | </syntaxHighlight> | ||

"Project Zomboid" may report "couldn't determine 32/64 bit of java". This is not related to java at all, it carries own outdated java binary that refuses to start if path contains non-latein characters. Check for errors by directly starting local java binary within <code>steam-run bash</code>. | |||
