Framework CPU Usage LED

Control the Framework Laptop's LED colors based on CPU usage. Inspired by this forum post.

Setup

Install fw-ectool. This can be installed on Arch Linux via fw-ectool-git on the AUR. Install psutil so the script can get CPU usage. This can be installed on Arch Linux via the python-psutil package.

Clone this repo and and edit the parameters inside cpu-usage-led.py like ledsToChange and privilegeEscalation. If you use privilegeEscalation = None, run the script as root.

When you have edited the script to your liking, run it. The script sets LEDs to the default behaviour when the lid is closed so there is no need to kill the script when the lid is closed. You can just run the script at boot.

Autostart using systemd

On systems using systemd, the Python script can be run automatically on boot. Note that the privilegeEscalation = None line should remain unchanged if used as a systemd service.

1. Move cpu-usage-led.py to /usr/bin/ so that /usr/bin/cpu-usage-led.py is present.
2. Move cpu-usage-led.service to /etc/systemd/system/ so that /etc/systemd/system/cpu-us age-led.service is present.
3. Run systemctl daemon-reload.
4. Run systemctl enable cpu-usage-led.service.
   • To launch the service now, run systemctl start cpu-usage-led.service.
