Configuration is now held by the `.org` files. All `.nix` files are tangled from the org-mode files.

* X Server
|
||
What’s left of =services.xserver= on my hosts now that GNOME runs on
|
||
Wayland: picking extra video drivers to load, and my own keyboard
|
||
layout. Here’s the skeleton of the =nixos.xserver= module.
|
||
#+begin_src nix :tangle yes
|
||
{
|
||
flake.modules.nixos.xserver = {
|
||
config,
|
||
lib,
|
||
...
|
||
}:
|
||
with lib; let
|
||
cfg = config.mySystem.desktop.xserver;
|
||
in {
|
||
<<options>>
|
||
<<config>>
|
||
};
|
||
}
|
||
#+end_src
|
||
|
||
** Declaring the Option
|
||
=videoDrivers= lets a host load extra X11 drivers, such as =amdgpu= on
|
||
the machine with an AMD GPU.
|
||
#+name: options
|
||
#+begin_src nix
|
||
options.mySystem.desktop.xserver.videoDrivers = mkOption {
|
||
type = types.listOf types.str;
|
||
default = [];
|
||
example = ["amdgpu"];
|
||
description = "Extra X11 video drivers to load";
|
||
};
|
||
#+end_src
|
||
|
||
** Enabling It
|
||
I use the same Bépo AFNOR keyboard layout everywhere, so it’s baked in
|
||
directly rather than exposed as an option.
|
||
#+name: config
|
||
#+begin_src nix
|
||
config.services.xserver = {
|
||
enable = true;
|
||
videoDrivers = cfg.videoDrivers;
|
||
xkb = {
|
||
layout = "fr";
|
||
variant = "bepo_afnor";
|
||
};
|
||
};
|
||
#+end_src
