The C720 comes with a Cypress APA touchpad. Support for this touchpad was added in kernel 3.17-rc1.
 | 
						|
In order to get the touchpad working CONFIG_CHROME_PLATFORMS needs to be enabled.
 | 
						|
 | 
						|
For example, for touchpad support with the 3.18 kernel, the following should be added to /etc/nixos/configuration.nix:
 | 
						|
 | 
						|
  boot.kernelPackages = pkgs.linuxPackages_3_18;
 | 
						|
  nixpkgs.config.packageOverrides = pkgs:
 | 
						|
    { linux_3_18 = pkgs.linux_3_18.override {
 | 
						|
        extraConfig =
 | 
						|
          '''''''
 | 
						|
            CHROME_PLATFORMS y
 | 
						|
          ''''''';
 | 
						|
      };
 | 
						|
    };
