+= Configuration =
+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
+          ''''''';
+      };
+    };
