Sway: Difference between revisions

[https://swaywm.org/ Sway] is a tiling [[Wayland]] compositor and a drop-in replacement for the [[i3]] window manager for X11. It can work with an existing i3 configuration and supports most of i3's features, plus a few extras. For users migrating from i3, see the [https://github.com/swaywm/sway/wiki/i3-Migration-Guide i3 migration guide].

By default, the Sway module in NixOS comes with a set of extra packages, including [https://codeberg.org/dnkl/foot/ Foot] terminal, [[Swayidle]], [[Swaylock]], and [https://codeberg.org/adnano/wmenu/ wmenu], which may be configured under the <code>[https://search.nixos.org/options?show=programs.sway.extraPackages programs.sway.extraPackages]</code> option. You may also want to include <code>wl-clipboard</code> for clipboard functionality, as well as a screenshot utility such as [https://github.com/emersion/slurp Slurp] or [[Flameshot]] for screenshot region selection.  

To set up Sway using [[Home Manager]], you must first enable [[Polkit]] in your NixOS configuration.

=== Using a greeter ===

Installing a greeter based on [[greetd]] is the most straightforward way to launch Sway.

Tuigreet is a simple and lightweight option that does not require a separate compositor to launch.

The snippet below will start Sway immediately on startup, without a greeter and '''without a login prompt'''. Only consider using this in conjunction with [[Full Disk Encryption]].

</syntaxhighlight>When launched directly from the TTY, Sway will not inherit the user environment. This may cause issues with systemd user services such as application launchers or [[Swayidle]]. To fix this, add the following to your Home Manager configuration:{{file|home.nix|nix|<nowiki>

Sway may be configured for specific users using Home Manager or manually through configuration files. The default location is <code>/etc/sway/config</code>, and custom user configuration in <code>~/.config/sway/config</code>.

<syntaxhighlight>seat "*" xcursor_theme Adwaita 32</syntaxhighlight>

Using [[Home Manager]] you may configure the mouse cursor size and theme. The reason that your cursor might be missing in some applications, is because <code>XCURSOR_THEME</code> is missing, which will cause applications relying on <code>XWAYLAND</code> to misbehave. Setting <code>sway.enable = true</code>, combined with the <code>name</code>, <code>package</code> and size will set the correct environment variables, which sway will then use.

{{File|3=home.pointerCursor = {

     name = "Adwaita";

    package = pkgs.adwaita-icon-theme;

    size = 24;

    x11 = {

      enable = true;

      defaultCursor = "Adwaita";

 

};|name=/etc/nixos/home.nix|lang=nix}}

=== Missing fonts in Xorg applications ===

If fonts for certain languages are missing in Xorg applications (e.g. Japanese fonts don't appear in Discord) even though they're in the system, you can set them as default fonts in your configuration file.

=== Screenshots ===
