Corsair

CORSAIR is an American computer peripherals and gaming brand.

Its possible to configure its keyboards an mice with an open source driver: ckb-next

Example config for ckb-next

# /etc/nixos/configuration.nix
{ config, pkgs, ... }:

{
  # ...
  hardware.ckb-next.enable = true;
}

Further configuration can be done: see the hardware.ckb-next options on search.nixos.org.

Limitations

Doing the above will enable the background service and install ckb-next. Yet (as of writing) you still have to manually run/open ckb-next on launch before it works.

If you find a way to automate this, please append to the wiki!
