How To Get Battery Notifications on Ubuntu 20.04

Ubuntu 6

In this article, we’ll guide you through the process of setting up battery notifications on Ubuntu 20.04. This can be particularly useful if you often find your laptop’s battery running low without any prior warning. While the Battery Monitor is not compatible with Ubuntu 20.04, there are several alternative solutions available. Let’s dive in!

Quick Answer

To get battery notifications on Ubuntu 20.04, you can adjust UPower settings, create a custom bash script, or install a battery monitoring tool such as tlp, acpi, or upower. Adjusting UPower settings allows you to set percentage thresholds for notifications, while creating a custom script gives you more control over the notifications. Installing a battery monitoring tool provides additional features and options for monitoring your battery.

Adjusting UPower Settings

UPower is a powerful tool that provides an interface to enumerate and query the status of power devices, as well as receive notifications for changes. You can adjust its settings to get battery notifications.

  1. Open the terminal: You can do this by pressing Ctrl + Alt + T or by searching for ‘Terminal’ in your system’s application menu.
  2. Navigate to the UPower directory: Use the cd command followed by the directory path. In this case, type cd /etc/UPower and press Enter.
  3. Open the UPower configuration file: Type sudo nano UPower.conf and press Enter. This command opens the configuration file in the nano text editor. The sudo prefix gives you administrative permissions, and nano is the text editor we’re using.
  4. Modify the configuration file: Look for the line that says UsePercentageForPolicy. Set this to true. This means that UPower will use the battery percentage to determine when to send notifications. You can then adjust the PercentageLow and PercentageCritical lines to your liking. For example, setting PercentageLow=50 will trigger a notification when your battery level drops to 50%.
  5. Save and exit: Press Ctrl + X to exit, then Y to confirm the changes, and finally Enter to save and close the file.
  6. Restart UPower: Run sudo systemctl restart upower for the changes to take effect.

Creating a Custom Script

If you want more control over your battery notifications, you can create a custom bash script.

  1. Create a new bash script: Open a new file in a text editor, such as nano. For example, nano battery_script.sh.
  2. Write your script: You can use the following as a starting point, and modify it to fit your needs:
    #!/bin/bash
    while true
    do
     battery_level=`acpi -b | grep -P -o '[0-9]+(?=%)'`
     if [ $battery_level -le 20 ]
     then
     notify-send "Battery low" "Battery level is ${battery_level}%!"
     fi
     sleep 60
    done
    This script checks the battery level every 60 seconds and sends a notification if the battery level is 20% or less.
  3. Make the script executable: Save the file and make it executable by running chmod +x battery_script.sh.
  4. Run the script: You can run the script manually by typing ./battery_script.sh in the terminal.
  5. Set the script to run automatically: If you want the script to run automatically every time you start your computer, you can add it to your crontab file. Type crontab -e in the terminal, then add a line at the end of the file like this: @reboot /path/to/your/script/battery_script.sh.

Installing a Battery Monitoring Tool

There are also various battery monitoring tools available in the Ubuntu repositories, such as tlp, acpi, or upower.

  1. Install a tool: Use the command sudo apt install tool_name to install the desired tool. Replace tool_name with the name of the tool you want to install.
  2. Check the tool’s documentation: Use man tool_name to access the tool’s manual and instructions on setting up notifications for low battery levels.

Remember to adjust the percentage thresholds and notification settings according to your preferences. We hope this guide helps you set up battery notifications on Ubuntu 20.04. If you have any questions or run into any issues, feel free to leave a comment below.
