For example, you might set it to sleep after 15 minutes of inactivity. You can also customize the behavior for different scenarios, such as when the lid is closed or when the system is idle.
• Fine-tune Power Options: Depending on your requirements, you can further refine the power settings. For instance, you can set the system to hibernate (a deeper sleep state) instead of sleeping, which can be useful for preserving the current session when you want to shut down quickly. You can also configure the system to dim the display or turn it off during sleep to save power.
• Test and Save Changes: After making the desired adjustments, test the new sleep settings by simulating different scenarios. You can manually put the system to sleep or simulate lid closure to see how it behaves. Once you're satisfied with the results, save the changes. The specific method to save settings may vary depending on your Ubuntu version and interface.

By configuring these power settings, you can ensure that your Ubuntu system sleeps and wakes up according to your preferences, optimizing power usage and providing a more personalized computing experience. Remember to experiment with different settings to find the best balance between power conservation and convenience.

Use Sleep Commands: Learn commands like `sudo shutdown -h now` to initiate a system sleep

To initiate a system sleep on Ubuntu, you can use the `shutdown` command with the `-h` option followed by `now`. This command will put your system to sleep immediately, saving your current session and powering down the computer. Here's a step-by-step guide:

• Open a Terminal: Start by opening a terminal window. You can do this by searching for "Terminal" in the application menu or using a keyboard shortcut like Ctrl + Alt + T.
• Use the Shutdown Command: In the terminal, type the following command and press Enter: `sudo shutdown -h now`. The `sudo` command is used to execute the command with administrative privileges, ensuring you have the necessary permissions to initiate a system sleep.
• Understand the Options: The `-h` option stands for "halt," which is a system-level command to power down the computer. The `now` parameter indicates that the action should be executed immediately. You can also use other options like `-s` (shutdown) or `-r` (reboot) with different time parameters, but for sleeping, `-h now` is the most appropriate.
• Confirm the Action: Before executing the command, Ubuntu will display a message asking you to confirm the action. Type `y` (yes) and press Enter to proceed. This step ensures that you are aware of the system's impending sleep and provides a safety mechanism.
