* Steam
|
|||
|
|
This module sets up Steam and gamescope for gaming on my desktop,
|
|||
|
|
along with a few tweaks for Proton and controller support. Here’s the
|
|||
|
|
skeleton of the =nixos.steam= module.
|
|||
|
|
#+begin_src nix :tangle yes
|
|||
|
|
{
|
|||
|
|
flake.modules.nixos.steam = {pkgs, ...}: {
|
|||
|
|
<<steam-enable>>
|
|||
|
|
<<remote-play>>
|
|||
|
|
<<gamescope-session>>
|
|||
|
|
<<proton-ge>>
|
|||
|
|
<<steam-package>>
|
|||
|
|
<<gamescope>>
|
|||
|
|
<<controller-support>>
|
|||
|
|
};
|
|||
|
|
}
|
|||
|
|
#+end_src
|
|||
|
|
|
|||
|
|
** Enabling Steam
|
|||
|
|
=protontricks= lets me run winetricks-style tweaks against a specific
|
|||
|
|
game’s own Proton prefix, which some finicky titles still need.
|
|||
|
|
#+name: steam-enable
|
|||
|
|
#+begin_src nix
|
|||
|
|
programs.steam.enable = true;
|
|||
|
|
programs.steam.protontricks.enable = true;
|
|||
|
|
#+end_src
|
|||
|
|
|
|||
|
|
** Remote Play and Local Transfers
|
|||
|
|
These punch the firewall holes Steam needs: one for streaming games
|
|||
|
|
over Remote Play, the other for transferring an install to another
|
|||
|
|
machine on the LAN instead of re-downloading it.
|
|||
|
|
#+name: remote-play
|
|||
|
|
#+begin_src nix
|
|||
|
|
programs.steam.remotePlay.openFirewall = true;
|
|||
|
|
programs.steam.localNetworkGameTransfers.openFirewall = true;
|
|||
|
|
#+end_src
|
|||
|
|
|
|||
|
|
** Proton-GE
|
|||
|
|
[[https://github.com/GloriousEggroll/proton-ge-custom][Proton-GE]] is a community Proton build with extra compatibility
|
|||
|
|
patches, and it often supports a game before official Proton catches
|
|||
|
|
up.
|
|||
|
|
#+name: proton-ge
|
|||
|
|
#+begin_src nix
|
|||
|
|
programs.steam.extraCompatPackages = [pkgs.proton-ge-bin];
|
|||
|
|
#+end_src
|
|||
|
|
|
|||
|
|
** The Steam Package Itself
|
|||
|
|
=OBS_VKCAPTURE= lets OBS Studio capture Vulkan games directly through
|
|||
|
|
game capture instead of a slower screen/window capture. =RADV_TEX_ANISO=
|
|||
|
|
forces anisotropic filtering on Mesa’s RADV driver for games that
|
|||
|
|
don’t expose the setting themselves. =atk= fixes some GTK-based Steam
|
|||
|
|
dialogs that otherwise complain about a missing accessibility toolkit,
|
|||
|
|
and the extra Qt5 and =libpulseaudio= packages patch up older games and
|
|||
|
|
launchers that load those libraries dynamically at runtime.
|
|||
|
|
#+name: steam-package
|
|||
|
|
#+begin_src nix
|
|||
|
|
programs.steam.package = pkgs.steam.override {
|
|||
|
|
extraEnv = {
|
|||
|
|
OBS_VKCAPTURE = true;
|
|||
|
|
RADV_TEX_ANISO = 16;
|
|||
|
|
};
|
|||
|
|
extraLibraries = p: with p; [atk];
|
|||
|
|
extraPkgs = pkgs:
|
|||
|
|
with pkgs; [
|
|||
|
|
qt5.qtmultimedia
|
|||
|
|
qt5.qtbase
|
|||
|
|
libpulseaudio
|
|||
|
|
];
|
|||
|
|
};
|
|||
|
|
#+end_src
|
|||
|
|
|
|||
|
|
** Gamescope
|
|||
|
|
[[https://github.com/ValveSoftware/gamescope][gamescope]] is Valve’s micro-compositor, the same one powering the
|
|||
|
|
session above. =capSysNice= lets it set realtime scheduling priority
|
|||
|
|
(=--rt=) without running as root, and =--expose-wayland= lets
|
|||
|
|
Wayland-native games run inside it directly instead of being forced
|
|||
|
|
through XWayland.
|
|||
|
|
#+name: gamescope
|
|||
|
|
#+begin_src nix
|
|||
|
|
programs.gamescope = {
|
|||
|
|
enable = true;
|
|||
|
|
capSysNice = true;
|
|||
|
|
args = [
|
|||
|
|
"--rt"
|
|||
|
|
"--expose-wayland"
|
|||
|
|
];
|
|||
|
|
};
|
|||
|
|
#+end_src
|
|||
|
|
|
|||
|
|
** Controller Support
|
|||
|
|
This installs the udev rules for the Steam Controller, Steam Deck
|
|||
|
|
controls, and other Valve input hardware, so they work without root.
|
|||
|
|
In my case, that’s my original Steam controller and Valve Index.
|
|||
|

#+name: controller-support
|
|||
|
|
#+begin_src nix
|
|||
|
|
hardware.steam-hardware.enable = true;
|
|||
|
|
#+end_src
