Asus touchpad numpad driver

Without % = symbols	With % = symbols	With % = symbols (but incompatible with the non-universal version)
Model/Layout = ux433fa	Model/Layout = m433ia	Model/Layout = ux581l

This is a python service which enables switching between numpad and touchpad for the Asus UX433. It may work for other models. When running the script, use as an argument one of the strings ux433fa or m433ia or `ux581l to select the layout that fits your touchpad. You can inspect the different layouts here.

Install required packages

• Debian / Ubuntu / Linux Mint / Pop!_OS / Zorin OS:

sudo apt install libevdev2 python3-libevdev i2c-tools git

• Arch Linux / Manjaro:

sudo pacman -S libevdev python-libevdev i2c-tools git

• Fedora:

sudo dnf install libevdev python-libevdev i2c-tools git

• NixOS:

Add these to your /etc/nixos/configuration.nix:

# i2c for https://github.com/mohamed-badaoui/asus-touchpad-numpad-driver
hardware.i2c.enable = true;
systemd.services.asus-touchpad-numpad = {
  description = "Activate Numpad inside the touchpad with top right corner switch";
  documentation = ["https://github.com/mohamed-badaoui/asus-touchpad-numpad-driver"];
  path = [ pkgs.i2c-tools ];
  script = ''
    cd ${pkgs.fetchFromGitHub {
      owner = "mohamed-badaoui";
      repo = "asus-touchpad-numpad-driver";
      # These needs to be updated from time to time
      rev = "d80980af6ef776ee6acf42c193689f207caa7968";
      sha256 = "sha256-AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA=";
    }}
    # In the last argument here you choose your layout.
    ${pkgs.python3.withPackages(ps: [ ps.libevdev ])}/bin/python asus_touchpad.py ux433fa
  '';
  # Probably needed because it fails on boot seemingly because the driver
  # is not ready yet. Alternativly, you can use `sleep 3` or similar in the
  # `script`.
  serviceConfig = {
    RestartSec = "1s";
    Restart = "on-failure";
  };
  wantedBy = [ "multi-user.target" ];
};

Then enable i2c

sudo modprobe i2c-dev
sudo i2cdetect -l

Now you can get the latest ASUS Touchpad Numpad Driver for Linux from Git and install it using the following commands.

git clone https://github.com/mohamed-badaoui/asus-touchpad-numpad-driver
cd asus-touchpad-numpad-driver
sudo ./install.sh

To turn on/off numpad, tap top right corner touchpad area. To adjust numpad brightness, tap top left corner touchpad area.

To uninstall, just run:

sudo ./uninstall.sh

Troubleshooting

To activate logger, do in a console:

LOG=DEBUG sudo -E ./asus_touchpad.py

For some operating systems with boot failure (Pop!OS, Mint, ElementaryOS, SolusOS), before installing, please uncomment in the asus_touchpad.service file, this following property and adjust its value:

# ExecStartPre=/bin/sleep 2
