The idea of this tool is to allow the user to change their backlight LED color at will. On my Gazelle, I can only cycle through preset colors, which is very limited, but with this tool, anything and everything is possible.

git clone https://github.com/jojo2357/system76-backlight-controller.git && cd system76-backlight-controller
sudo ./backlight-installerAfter installation, you can interface the controller via
backlight-controller
but note that most of the commands require root privileges.
| Name | Options | Description |
|---|---|---|
| start | NONE | Starts the executor running |
This tool works by creating a systemd service that runs a script with root privileges. That script will do whatever hoop-jumping it wants in order to determine what color it wants to set the backlight color to.
After installation, you will have a script called /usr/local/bin/export-keyboard-color
This script requires root, and takes either one arg with the hex code of the color you want to set (DO NOT INCLUDE 0x or #! ONLY the 6 digits matching /[0-9A-Fa-f]/) or three args in base 10 as R, G, and B, respectively.
In order to do this, you need to write a script that can be executed using a shebang (ex #!/bin/bash or #!/bin/python3) and your system must support said shebang. Note that since the script will run as root, any deps need to be installed using root (mostly talking about you, PIP)
This repo already has some controllers, or "Executors" provided that you can use using the set subcommand. They are as follows
| File | Has Deps | Requires | Description |
|---|---|---|---|
| rainbow.sh | N | bash |
Cycles through the rainbow |
| solid-orange | N | bash |
Sets the backlight to a nice orange color |
| solid-pythorange | Y | python3,keyboard |
Sets the backlight to orange, and changes to blue when any key is pressed |
| ram-monitor | Y | python3,psutil |
Changes backlight from green to red based on the system resource utilization (ram & cpu) |
| modifier-keys | Y | python3,keyboard |
Changes the backlight color whenever a modifier key is pressed (shift/ctrl/alt) |
Feel free to use these for inspiration.
