The easiest way to customize your keyboard layout on NixOS is with these options: | The easiest way to customize your keyboard layout on NixOS is with these options: | ||
* <code>services.xserver.layout</code>: Keyboard layout, or multiple keyboard layouts separated by commas. | * <code>services.xserver.xkb.layout</code>: Keyboard layout, or multiple keyboard layouts separated by commas. | ||
* <code>services.xserver. | * <code>services.xserver.xkb.variant</code>: X keyboard variant or multiple variants separated by commas (a variant can be empty). | ||
* <code>services.xserver. | * <code>services.xserver.xkb.model</code>: Keyboard model. | ||
* <code>services.xserver. | * <code>services.xserver.xkb.options</code>: X keyboard options; layout switching goes here. | ||

For desktop: | |||
<syntaxhighlight lang="nix"> | |||
services.xserver.xkb = { | |||
layout = "us,ru"; | |||
variant = "workman,"; | |||
options = "grp:win_space_toggle"; | |||

For console: | |||
<syntaxhighlight lang="nix"> | |||
console.keyMap = "us"; | |||

You may need to add some delay to make xmodmap command work. | |||
<syntaxhighlight lang="nix"> | |||
