 -----------------
 Wayland has a somewhat different tack: It uses xkb-data files, but not an X server. So the setkb script won't work there, but the BigBag as such will.
 
-It depends on which Wayland Compositor you're using. See its docs for more info?

 The repeat settings are of course optional. Some like a higher repeat rate and a lower delay, and this is how to get that.

 In NixOS without Wayland/Sway, [services.xserver](https://nixos.wiki/wiki/Keyboard_Layout_Customization) should work:
 ```
 services.xserver = {
   layout = "us";
-  xkbVariant = "cmk_ed_us";
+  xkbVariant = "cmk_ed_dh";
   xkbModel   = "pc105awide";
-  xkbOptions = "misc:extend,lv5:caps_switch_lock,misc:cmk_curl_dh,compose:menu";
+  xkbOptions = "misc:extend,lv5:caps_switch_lock,compose:menu";
 };
 ```
 To get the xserver layout in your console as well, use `console.useXkbConfig` in your `configuration.nix` file.
