Keyboard Brightness Control Setup

Configure Brightness Control Shortcuts​

1. Copy Brightness Scripts​

# Download launcher scripts from GitHub
mkdir ~/Typeframe
cd ~/Typeframe
wget https://raw.githubusercontent.com/jeffmerrick/typeframe/refs/heads/main/px-88/software/brightness_up.sh
wget https://raw.githubusercontent.com/jeffmerrick/typeframe/refs/heads/main/px-88/software/brightness_down.sh

Make sure these scripts are executable:

chmod +x ~/Typeframe/brightness_*.sh

2. Configure labwc Keyboard Shortcuts​

Add the following keyboard shortcuts to your ~/.config/labwc/rc.xml file, creating it if it doesn't already exist:

<?xml version="1.0"?>
<openbox_config xmlns="http://openbox.org/3.4/rc">
	<!-- Your existing configuration -->

	<keyboard>
		<!-- Hardware brightness keys (if configured in VIA) -->
		<keybind key="XF86MonBrightnessUp">
			<action name="Execute">
				<command>/bin/sh -c '$HOME/Typeframe/brightness_up.sh'</command>
			</action>
		</keybind>
		<keybind key="XF86MonBrightnessDown">
			<action name="Execute">
				<command>/bin/sh -c '$HOME/Typeframe/brightness_down.sh'</command>
			</action>
		</keybind>

		<!-- Alternative shortcuts using Super + Arrow keys -->
		<keybind key="W-Up">
			<action name="Execute">
				<command>/bin/sh -c '$HOME/Typeframe/brightness_up.sh'</command>
			</action>
		</keybind>
		<keybind key="W-Down">
			<action name="Execute">
				<command>/bin/sh -c '$HOME/Typeframe/brightness_down.sh'</command>
			</action>
		</keybind>
	</keyboard>
</openbox_config>

3. Reload labwc Configuration​

After editing the rc.xml file, reload the labwc configuration:

labwc-pi --reconfigure

or reboot:

sudo reboot

4. Test Brightness Controls​

You can now control brightness using:

  • Hardware Brightness Keys (I configured as MO(1) + PgUp and MO(1) + PgDown in VIA)
  • Super + Up Arrow - Increase brightness
  • Super + Down Arrow - Decrease brightness
