Integrating Power Profiles Daemon into Waybar

This guide explains how to integrate the power-profiles-daemon.service into Waybar, providing a toggleable button to switch between power profiles.

Prerequisites

Ensure you have the following installed:

waybar (version 0.9.22 or later recommended)
power-profiles-daemon

1. Waybar Configuration

Add the power-profiles-daemon module to your Waybar configuration file (typically located at ~/.config/waybar/config).

{
    "modules-right": [
        "power-profiles-daemon",
        // ... other modules
    ],

    "power-profiles-daemon": {
        "format": "{icon}",
        "tooltip-format": "Power profile: {profile}\nDriver: {driver}",
        "tooltip": true,
        "format-icons": {
            "default": "",
            "performance": "⚡",
            "balanced": "",
            "power-saver": ""
        }
    }
}

2. Automatic Toggling

Waybar's built-in power-profiles-daemon module automatically cycles through available profiles when clicked. You don't need a separate script for basic toggling. However, if you want a custom script for more complex behavior, you can use a custom/power_profile module instead.

Using the Built-in Module (Recommended)

The built-in module is the most efficient way to handle this. It interacts directly with the daemon via D-Bus.

Custom Toggle Script (Optional)

If you prefer a custom script, create a file at ~/.config/waybar/scripts/toggle_power_profile.sh:

#!/bin/bash

current_profile=$(powerprofilesctl get)

case $current_profile in
    "power-saver")
        powerprofilesctl set balanced
        ;;
    "balanced")
        powerprofilesctl set performance
        ;;
    "performance")
        powerprofilesctl set power-saver
        ;;
    *)
        powerprofilesctl set balanced
        ;;
esac

Make it executable:

chmod +x ~/.config/waybar/scripts/toggle_power_profile.sh

Then, use a custom module in your Waybar config:

"custom/power_profile": {
    "exec": "powerprofilesctl get",
    "interval": 30,
    "on-click": "~/.config/waybar/scripts/toggle_power_profile.sh",
    "format": "Profile: {}"
}

3. Styling (Optional)

You can style the module in your style.css:

#power-profiles-daemon {
    padding-left: 10px;
    padding-right: 10px;
}

#power-profiles-daemon.performance {
    background-color: #f38ba8;
    color: #1e1e2e;
}

#power-profiles-daemon.balanced {
    background-color: #a6e3a1;
    color: #1e1e2e;
}

#power-profiles-daemon.power-saver {
    background-color: #89b4fa;
    color: #1e1e2e;
}
