# Asus Zenbook Pro UX535

Tested on a slightly modified device - the Intel Optane combination SSD was replaced with a higher capacity Sabrent Drive. From Using the Optane Drive without Optane Mode in Windows, I hypothesise that the drive should work assuming the BIOS Settings are Correct - I believe there was a RAID mode I turned off? In Windows, the Optane blocks appeared as a separate drive, I'd suggest maybe use this as Swap?

## ScreenPad:

Configuration for the ScreenPad is unable to be provided here at this time, due to reliance on Additional Modules not included in Nixpkgs. If you want to install the [ScreenPad Kernel Module](https://github.com/Plippo/asus-wmi-screenpad), I recommend using the packaging of it for nix created by [MatthewCash](https://github.com/MatthewCash/asus-wmi-screenpad-module). It can be installed as below:

```nix
# flake.nix
{
  inputs = {

    nixpkgs = {
      url = "github:NixOS/nixpkgs/nixos-unstable";
    };

    screenpad-driver={
        url = "github:MatthewCash/asus-wmi-screenpad-module";
        inputs.nixpkgs.follows="nixpkgs";
      };

  };
  outputs = inputs@{nixpkgs, screenpad-driver, ...}:{

    # Replace hostname with your hostname
    nixosConfigurations.hostname=inputs.nixpkgs.lib.nixosSystem{
      modules = [
        ./configuration.nix
        {
          boot.extraModulePackages = let
            screenpad-driver-package = (kernelPackage:
              let
              asus-wmi-screenpad = screenpad-driver.defaultPackage.${system}.override{kernel=kernelPackage;};
              in [
                asus-wmi-screenpad
              ]
            );
            in (screenpad-driver-package ${yourKernelPackages}.kernel); # Replace ${yourKernelPackages} with the value of your config.boot.kernelPackages, for me, this would be pkgs.kernelPackages_latest
          boot.kernelModules = [
            "asus-wmi-screenpad"
          ];
        }
      ];
    };

  };
}

```

I also recommend writing some kind of script to be able to turn the screenpad On and Off with the correct positioning. If you're using KDE Plasma, feel free to use [mine](https://github.com/Green-D-683/Asus-ScreenPad-Linux). You may also want a script to be able to turn on the main display, as it has an irritating habit of turning itself off, making the screenpad the primary display whenever you plug in a new monitor configuration.

## Battery charging limit:

Due to the common module for ASUS batteries, you can make your battery only charge up to a certain percentage to improve its life. You can place something similar to the following in your configuration to enable it.

```nix
hardware.asus.battery =
{
  chargeUpto = 90;   # Maximum level of charge for your battery, as a percentage.
  enableChargeUptoScript = true; # Whether to add charge-upto to environment.systemPackages. `charge-upto 100` temporarily sets the charge limit to 100%, useful if you're going to need the extra battery on a longer journey.
};
```

## Thunderbolt:

I don't own any Thunderbolt devices to be able to test transfer speeds or PCIe Tunnelling, but I've tested both USB Monitors and Display-Out though the Thunderbolt 3 port and both seem to work well.
