Tip: This package is unfree, and will require extra steps to install. You can read more about allowing unfree software in the Nixpkgs Manual.

Slack is a communication platform with a desktop application based on Electron.

Installation

NixOS

environment.systemPackages = with pkgs; [ slack ];

Tips

Wayland

You can enable native Wayland support by launching Slack as:

$ NIXOS_OZONE_WL=1 slack

... or by simply specifying this option globally:

environment.sessionVariables.NIXOS_OZONE_WL = "1";

If you want to use screen-sharing, you'll have to enable xdg-desktop-portal, too:

xdg = {
  portal = {
    enable = true;
    extraPortals = with pkgs; [
      xdg-desktop-portal-wlr
      xdg-desktop-portal-gtk
    ];
  };
};

Window decorations

If the above configuration leaves you without window decorations you may want to enable this feature as well:

-Since Electron's support for Wayland is of somewhat beta-quality, by default Slack will run through Xwayland, making it hard to do screen-sharing or use it comfortably on 4k+ screens - fortunately, it's possible to run it natively by specifying a few parameters:
