Dell G15 5530 fan control on Arch Linux (Hyprland)

This article explains how to install and configure the dell-g15-controller utility on Arch Linux running the Hyprland Wayland compositor, to control fan speed, power profiles, and keyboard backlight on Dell G15 5530 and similar Dell G-series laptops.

The dell-g15-controller requires kernel support via the acpi_call module, Polkit for privilege escalation, and a Polkit authentication agent, which is not included by default in Hyprland.

Dependencies

  • python (for running the controller)
  • Kernel module acpi_call
  • dell-g15-controller (available from AUR)
  • Polkit and a Polkit authentication agent (e.g. lxsession)

Installation

Required packages

Install the linux-headers package. Install the following packages from the AUR: acpi, acpi_call-dkms, lxsession, dell-g15-controller, python-pexpect, and python-pyside6. 

sudo modprobe acpi_call
Note: Based on Dell-G-Series-Controller

Udev rule for controller

Create the file /etc/udev/rules.d/00-aw-elc.rules with the following content: 

SUBSYSTEM=="usb", ATTRS{idVendor}=="187c", ATTRS{idProduct}=="0550", MODE="0660", TAG+="uaccess", SYMLINK+="awelc"

Reload udev rules with: 

$ sudo udevadm control --reload

Enable Polkit authentication agent

Using Hyprland config file

Add the following line to your Hyprland config (usually ~/.config/hypr/hyprland.conf): 

exec-once = /usr/bin/lxpolkit
Tip: You can find the location of lxpolkit by running which lxpolkit

Restart Hyprland or run the agent manually before launching the controller.

Run manually

Start the Polkit authentication agent in a new terminal: 

$ lxpolkit

Usage

Find the location of the main controller script: 

$ yay -Ql dell-g15-controller | grep main.py

This will output something like: 

dell-g15-controller /opt/dell-g-series-controller/main.py

Run the controller using Python: 

$ python /opt/dell-g-series-controller/main.py

When prompted, enter your password via the Polkit GUI dialog.

Use the GUI to control fan speed, power modes, and keyboard backlight.

Troubleshooting

  • If the GUI hangs on startup, ensure a Polkit authentication agent is running.
  • Check that the acpi_call module is loaded:
$ lsmod | grep acpi_call
  • Verify the udev rule exists and that the USB device permissions are correct.
