* OpenTabletDriver
Some of my machines are hooked up to a graphics tablet, a Wacom
Bamboo, driven by [[https://opentabletdriver.net/][OpenTabletDriver]]. I remember buying it for 15€, what
a deal that was! Anyway, since most of my hosts don’t have a tablet
attached, this is exposed as a regular toggle rather than enabled
unconditionally. Here’s the skeleton of the =nixos.opentablet= module.
#+begin_src nix :tangle yes
{
  flake.modules.nixos.opentablet = {
    <<config>>
  };
}
#+end_src

** Enabling the Driver
Enabling OpenTabletDriver proper is just a matter of turning on the
module and its daemon. I also need to explicitly load the =wacom=
kernel module, since my tablet (like most of them) identifies itself
as a Wacom device at the hardware level regardless of brand.
#+name: config
#+begin_src nix
hardware.opentabletdriver = {
  enable = true;
  daemon.enable = true;
};
boot.kernelModules = ["wacom"];
#+end_src
