It is possible to install custom [ XKB

](https://en.wikipedia.org/wiki/X_keyboard_extension) keyboard layouts

using the option `services.xserver.extraLayouts`.

using the option `services.xserver.xkb.extraLayouts`.

As a first example, we are going to create a layout based on the basic

US layout, with an additional layer to type some greek symbols by

A minimal layout specification must include the following:

```nix

services.xserver.extraLayouts.us-greek = {

services.xserver.xkb.extraLayouts.us-greek = {

  description = "US layout with alt-gr greek";

  languages   = [ "eng" ];

  symbolsFile = /yourpath/symbols/us-greek;

As before, to install the layout do

```nix

services.xserver.extraLayouts.media = {

services.xserver.xkb.extraLayouts.media = {

  description  = "Multimedia keys remapping";

  languages    = [ "eng" ];

  symbolsFile  = /path/to/media-key;

  order, or relying on `mkBefore` and `mkAfter`, but may impact users calling

  `mkOrder n` with n ≤ 400.

- X keyboard extension (XKB) options have been reorganized into a single attribute set, `services.xserver.xkb`. Specifically, `services.xserver.layout` is now `services.xserver.xkb.layout`, `services.xserver.xkbModel` is now `services.xserver.xkb.model`, `services.xserver.xkbOptions` is now `services.xserver.xkb.options`, `services.xserver.xkbVariant` is now `services.xserver.xkb.variant`, and `services.xserver.xkbDir` is now `services.xserver.xkb.dir`.

- X keyboard extension (XKB) options have been reorganized into a single attribute set, `services.xserver.xkb`. Specifically, `services.xserver.layout` is now `services.xserver.xkb.layout`, `services.xserver.extraLayouts` is now `services.xserver.xkb.extraLayouts`, `services.xserver.xkbModel` is now `services.xserver.xkb.model`, `services.xserver.xkbOptions` is now `services.xserver.xkb.options`, `services.xserver.xkbVariant` is now `services.xserver.xkb.variant`, and `services.xserver.xkbDir` is now `services.xserver.xkb.dir`.

- `networking.networkmanager.firewallBackend` was removed as NixOS is now using iptables-nftables-compat even when using iptables, therefore Networkmanager now uses the nftables backend unconditionally.

- The `services.mtr-exporter.target` has been removed in favor of `services.mtr-exporter.jobs` which allows specifying multiple targets.

- `blender-with-packages` has been deprecated in favor of `blender.withPackages`, for example `blender.withPackages (ps: [ps.bpycv])`. It behaves similarly to `python3.withPackages`.

- Setting `nixpkgs.config` options while providing an external `pkgs` instance will now raise an error instead of silently ignoring the options. NixOS modules no longer set `nixpkgs.config` to accomodate this. This specifically affects `services.locate`, `services.xserver.displayManager.lightdm.greeters.tiny` and `programs.firefox` NixOS modules. No manual intervention should be required in most cases, however, configurations relying on those modules affecting packages outside the system environment should switch to explicit overlays.

- `service.borgmatic.settings.location` and `services.borgmatic.configurations.<name>.location` are deprecated, please move your options out of sections to the global scope.
