usr/share/dbus-1/system.d/ provide amazing battery life, and most run Android apps thanks to Chrome OS support for the Google Play Store. To prevent automatic lighting up just edit file /usr/share/dbus-1/system.d/ as follows (two occurrences of 'deny'): After that you can control keyboard backlight only via hotkeys (eg. The only triggers remain plugging in the adapter and fresh boot. Following setup prevent from automatic lighting up during any action. In case you use MATE environment you might get tired with repeated lighting keyboard backlight while logging in, unlocking screen or waking up dimmed display. Reason: Informal and unclear description. $ gdbus call -session -dest -object-path /org/gnome/SettingsDaemon/Power -method .Keyboard.StepDown $ gdbus call -session -dest -object-path /org/gnome/SettingsDaemon/Power -method .Keyboard.StepUp The following can be run from a terminal or mapped to keybindings Print('Script takes one or two argument.', len(sys.argv) - 1, 'arguments provided.')Īlternatively the following bash one-liner will set the backlight to the value specified in the argument:ĭbus-send -system -type=method_call -dest='' '/org/freedesktop/UPower/KbdBacklight' '.SetBrightness' int32:$1 If sys.argv = '-up' or sys.argv = '+':Įlif sys.argv = '-down' or sys.argv = '-': If len(sys.argv) = 2 or len(sys.argv) = 3: # Return current backlight level percentage New = max(0, min(current + delta, maximum)) Maximum = kbd_backlight.GetMaxBrightness() Kbd_backlight = dbus.Interface(kbd_backlight_proxy, '') Kbd_backlight_proxy = bus.get_object('', '/org/freedesktop/UPower/KbdBacklight') Tip: You should try with an x = 1 to determine the limits of the keyboard backlight levels /usr/local/bin/kb-light.py #!/usr/bin/env python3 You can then map your keyboard shortcuts to run /usr/local/bin/kb-light.py + x and /usr/local/bin/kb-light.py - x to increase and decrease your keyboard backlight level by x amounts.

Install upower and dbus-python packages then place the following script in /usr/local/bin/ and make it executable. The following is an example implementation in Python 3. The benefits of using it are that no modification to device files is required and it is vendor agnostic. You can control your computer keyboard backlight via the D-Bus interface. The first parameter led turns on the led, and -led turns it off, the NUMBER parameters accepts integers for 1 to 32 (each number corresponds to a led in you system, keyboards seem to generally be number 3), or 'on' and 'off' (on will turn ALL lights on, and off will turn ALL lights off). Some keyboard manufactores are not recognized by brightnessctl or light, but you can use xorg-xset to control its lights if you are running Xorg. $ brightnessctl -device='tpacpi::kbd_backlight' set 1 This will show the absolute and relative current value and the maximum absolute value. $ brightnessctl -device='tpacpi::kbd_backlight' info When using brightnessctl you can get a list of available brightness controls with brightnessctl -list, then to show the kbd backlight information: # echo 1 > /sys/class/leds/tpacpi::kbd_backlight/brightness $ cat /sys/class/leds/tpacpi::kbd_backlight/max_brightness For example to get the maximum brightness level: The current brightness level can be get by reading /sys/class/leds/tpacpi::kbd_backlight/brightness. The sys pseudo-file system exposes an interface to the keyboard backlight. There are a variety ways to manage the brightness level and different helpers tools to accomplish this, such as brightnessctl or light.
