The gnome desktop portal does get installed by the nixos module already. installing them into system/user path was never correct to begin with too.

You might want to start from [https://github.com/YaLTeR/niri/blob/main/resources/default-config.kdl the default configuration file] described at [https://github.com/YaLTeR/niri/wiki/Getting-Started#main-default-hotkeys].

== Additional Setup ==


As described in [https://github.com/YaLTeR/niri/wiki/Example-systemd-Setup Example systemd Setup (Niri wiki)], you might want to set up some additional services including [[Swayidle]], [[Swaylock]], [[Waybar]], [[Polkit]] and [[Secret Service]] as follows to complement the functionality of a regular window manager. Some of the these settings are also required to enable all the features of [https://github.com/YaLTeR/niri/blob/main/resources/default-config.kdl the default configuration file].

== Troubleshooting ==
=== IME not working on Electron apps ===
There is a general workaround to set {{ic|NIXOS_OZONE_WL}} as described in [[Wayland#Electron_and_Chromium]]:
</translate>


{{file|/etc/nixos/configuration.nix|nix|3=
{{file|/etc/nixos/configuration.nix|nix|3=
security.polkit.enable = true; # polkit
environment.sessionVariables.NIXOS_OZONE_WL = "1";
services.gnome.gnome-keyring.enable = true; # secret service
security.pam.services.swaylock = {};
}}
}}


<translate>
However, since niri does not support text-input-v1, sometimes enabling text-input-v3 by manually adding {{ic|<nowiki>--wayland-text-input-version=3</nowiki>}} flag is necessary for IME to work:
</translate>
{{code|<nowiki>slack --wayland-text-input-version=3</nowiki>}}
<translate>
<code>wrapProgram</code> may be used to add the flag automatically:
</translate>
{{file|/etc/nixos/configuration.nix|nix|3=
environment.systemPackages = [
  (pkgs.symlinkJoin {
    pname = pkgs.vscode.pname;
    paths = [ pkgs.vscode ];
    buildInputs = [ pkgs.makeWrapper ];
    postBuild = "wrapProgram $out/bin/code --add-flags --wayland-text-input-version=3";
  };)
];}}
<translate>
=== XWayland apps not working ===
There is a optional dependency for niri which is highly recommended to install (you can read [https://github.com/YaLTeR/niri/wiki/Xwayland this] article to learn more about this)
</translate>
{{File|3=environment.systemPackages = with pkgs; [
    xwayland-satellite # xwayland support
];|name=/etc/nixos/configuration.nix|lang=nix}}
<translate>
Or using [[Home Manager]]
</translate>
{{File|3=home.packages = with pkgs; [
  xwayland-satellite # xwayland support
];|name=~/.config/home-manager/home.nix|lang=nix}}
<translate>
After you installed {{ic|xwayland-satellite}} niri will integrate it out of the box and all of your XWayland apps will function properly.
=== File picker not working ===
If you are using <code>xdg-desktop-portal-gnome</code>, it will attempt to use Nautilus as the file picker, which will fail if Nautilus is not installed.
To work around this problem, you can force usage of the gtk or kde portals for file picker instead:
</translate>
{{File|3=xdg.portal.config.niri = {
  "org.freedesktop.impl.portal.FileChooser" = [ "gtk" ]; # or "kde"
};|name=/etc/nixos/configuration.nix|lang=nix}}
