Installaton

IN PROGRESS

check the requirements section of your controller and make sure everything is working!

• Lenovo

Supported Models

There are different controllers for different devices. The controllers define the available options (eg.: colors, speed, effect, ...).

Controller Name	Description	Compatible Models
lenovo	Based on InstinctEx's lenovo-ideapad-legion-keyboard-led project. It uses pyusb.	Lenovo Ideapad Gaming 3 or Legion 5 Pro

Configuration

see the example config.toml

Keylightctl expects configuration file in $HOME/.config/keylightctl/config.toml. You can specify other locations using the keylightctl -C CONFIG flag.

Controller

Choosing controller to use (you MUST set this):

[controller]
active_controller = "lenovo"

Controller specific configurations:

[controller.lenovo]
usb_vendor = "0x048D"
usb_product = "0xC963"

Defining templates

Everything except description is an option provided by controllers.

[template.choose_a_name]
description = "white"
effect = "static"
colors = ["ffffff"]

Usage

# Turn on/off:
keylightctl turn ON/OFF

# Toggle on/off:
keylightctl toggle

Check out the usage section of your controller, for the available options of set command and templates:

• Lenovo

Templates

# Activate a template:
keylightctl template [TEMPLATE_NAME]

# List templates: 
keylightctl list

Others

# Disable/Enable
keylightctl disable/enable

# Show the current options
keylightctl show

# Show the details of a template
keyligthctl show TEMPLATE_NAME

If you are using keylightctl --no-persist flag, the new options won't be remembered (either using set or template) and turn on will reset to the saved options.

Tips

I you find a good usecase, feel free to share!

Warning light

1. Create a template which flashes the keyboard in red.
2. Run keylightctl --no-persist template WARNING_TEMPLATE_NAME to warn you
3. Reset it back to previous using keylight turn on

Notifications

Something similar to the previous triggered by notifications.

Use keybindings

You can you keybindings based on templates.

Turn on keyboard lightning periodacially

You can create a cron job for example to turn on your keyboard lightning at night.

You may use weather data, integrate with system dark/light mode, etc.

Disable/ Enable for idle management

You can do something like this in hypridle.conf for example:

# turn off keyboard backlight, comment out this section if you dont have a keyboard backlight.
listener { 
    timeout = 150                                          # 2.5min.
    on-timeout = keylight disable
    on-resume = keylight enable
}
