Automatically Starting TLP on Ubuntu Boot and Switching Modes

Ubuntu 7

TLP is a powerful tool that can help you manage your Ubuntu system’s power consumption. By default, TLP is designed to automatically start when your system boots up and adjust its settings based on your system’s power mode. This article will guide you through the process of checking if TLP is running, enabling it to start automatically, and understanding how it switches modes.

Quick Answer

To automatically start TLP on Ubuntu boot, you can enable it as a startup application by adding the command "sudo tlp start" in your system’s "Startup Applications" settings. TLP will then adjust its settings based on your system’s power mode, optimizing power consumption on AC power and battery power.

Checking if TLP is Running

To check if TLP is running on your system, you can use the terminal. Open a terminal by pressing Ctrl + Alt + T and type the following command:

sudo tlp-stat -s

The sudo command is used to run the following command with administrative privileges. tlp-stat -s is the command to check the status of TLP. If TLP is running, you will see an output indicating its status.

Enabling TLP to Start Automatically

Although TLP should start automatically by default, if you are experiencing issues, you can try enabling it as a startup application. To do this, follow these steps:

  1. Open your system’s “Startup Applications” settings.
  2. Click on “Add” to add a new entry.
  3. In the “Command” field, enter sudo tlp start.

The command sudo tlp start is used to start TLP with administrative privileges.

Handling Issues with Systemctl

If you encounter the error systemctl: command not found when trying to enable TLP, it means that the systemctl command is not available on your system. This could be due to using an older version of Ubuntu or a different Linux distribution. In this case, you can use the service command instead:

sudo service tlp start

The service command is a utility for managing services in Linux. The tlp start command is used to start the TLP service.

Understanding TLP’s Mode Switching

TLP is designed to automatically adjust its settings based on whether your system is running on AC power or battery power. You do not need to manually switch modes or start TLP again when the power mode changes.

This automatic mode switching is one of the key features of TLP that helps it optimize your system’s power consumption. It uses different sets of configurations for AC and battery power to ensure that your system uses the optimal power settings for each mode.

In conclusion, TLP is a powerful tool for managing power consumption on Ubuntu systems. By understanding how to check its status, enable it to start automatically, and how it switches modes, you can ensure that your system is always running with the optimal power settings.

How can I check if TLP is running on my Ubuntu system?

To check if TLP is running, open a terminal using Ctrl + Alt + T and enter the command sudo tlp-stat -s. This command will display the status of TLP.

How can I enable TLP to start automatically on boot?

TLP should start automatically by default. However, if it’s not, you can add it as a startup application by opening the "Startup Applications" settings, clicking on "Add," and entering sudo tlp start in the "Command" field.

What should I do if I encounter the error “systemctl: command not found” when trying to enable TLP?

If you encounter this error, it means that the systemctl command is not available on your system. In that case, you can use the service command instead. Enter sudo service tlp start in the terminal to start the TLP service.

How does TLP switch modes based on power source?

TLP automatically adjusts its settings based on whether your system is running on AC power or battery power. It uses different configurations for each mode to optimize power consumption. You don’t need to manually switch modes or start TLP again when the power source changes.
