Description

TUXEDO Computers kernel module drivers for keyboard, keyboard backlight & general hardware I/O

Features

• Driver for Fn-keys
• Sysfs control of brightness/color/mode for most TUXEDO keyboards (note: white backlight only models are currently not supported)
• Hardware I/O driver for TUXEDO Control Center

Modules included in this package

• tuxedo-keyboard
• tuxedo-io
• clevo-wmi
• clevo-acpi

Building and Install

Dependencies:

• make
• gcc
• linux-headers
• dkms (Only when using this module with DKMS functionality)

Warning when installing the module:

Use either method only. Do not combine installation methods, such as starting with the build step below and proceeding to use the same build artifacts with the DKMS module. Otherwise the module built via dkms will fail to load with an exec_format error on newer kernels due to a mismatched version magic.

This is why the DKMS build step begins with a make clean step.

For convenience, on platforms where DKMS is in use, skip to the DKMS section directly.

Clone the Git Repo:

git clone https://github.com/tuxedocomputers/tuxedo-keyboard.git

cd tuxedo-keyboard

git checkout release

Build the Module:

make clean && make

The DKMS route:

Add as DKMS Module:

Install the Module:

make clean

sudo make dkmsinstall

Load the Module with modprobe:

modprobe tuxedo_keyboard

or

sudo modprobe tuxedo_keyboard

You might also want to activate tuxedo_io module the same way if you are using TCC.

Uninstalling the DKMS module:

Remove the DKMS module and source:

sudo make dkmsremove

sudo rm /etc/modprobe.d/tuxedo_keyboard.conf

Using

modprobe

modprobe tuxedo_keyboard

Load the Module on boot:

If a module is relevant it will be loaded automatically on boot. If it is not loaded after a reboot, it most likely means that it is not needed.

Add Module to /etc/modules

sudo su

echo tuxedo_keyboard >> /etc/modules

Default Parameters at start.

In this example, we start the kernel module with the following settings:

• mode 0 (Custom / Default Mode)
• red color for the left side of keyboard
• green color for the center of keyboard
• blue color for the right side of keyboard

Note that we write it's settings to a .conf file under /etc/modprobe.d named tuxedo_keyboard.conf.

sudo su

echo "options tuxedo_keyboard mode=0 color_left=0xFF0000 color_center=0x00FF00 color_right=0x0000FF" > /etc/modprobe.d/tuxedo_keyboard.conf

or

sudo cp tuxedo_keyboard.conf /etc/modprobe.d/tuxedo_keyboard.conf
