How to Keep Linux Awake and Prevent Screen Sleep

Gnome (Caffeine)

Time needed: 2 minutes

To keep a Linux machine running Gnome from sleeping and turning off the display:

  1. Install the Caffeine Gnome shell extension.

    Here’s why: The extension will both offer a simple way to keep Linux from sleeping and allow you to automate the job, e.g., for certain applications.
    Here’s how: You can use Extension Manager, for instance, to download and install Caffeine.

  2. Click the Gnome quick settings menu to the status bar’s right.

    Gnome keyboard shortcut: Press Super S to open the menu.

  3. Select Caffeine to prevent system and screen from sleeping or locking.

Prevent KDE Linux from Sleeping (Stimulator)

To prevent a KDE Linux desktop from sleeping, turning off the display or running a screensaver:

    Not just KDE: Stimulator also works with Gnome as a (simpler) alternative to the Caffeine shell extension.

Keep Linux Awake from a Terminal (Wakepy)

To stop a Linux machine from either going to sleep or (also) from turning off the screen using a command-line utility:

  1. Install wakepy.
    Prerequisite: Wakepy is a Python script, so Python3 needs to be installed on the machine.
    Here’s how: Typically, pip install wakepy will install wakepy most conveniently, but other methods are possible as well.
  2. Run wakepy -p on a command line to keep both computer and display awake.
    Display snooze: Alternatively, run wakepy -r to keep the computer running but allow the display to turn off.

How to Keep a Linux Computer and Screen Awake: FAQ

Can I have an application always prevent sleep?

Yes.

Using Caffeine, for instance, you can set up applications that always engage it when running, on the active workspace or in focus. While control is not more granular than that — e.g., different actions for conditions set by app — , it is a start.

To have an application enable Caffeine automatically:

  1. Open Caffeine settings.
    Here’s how: You can access settings from Extensions or Extension Manager, for example.
  2. Go to the Apps tab.
  3. Click + Add.
  4. Highlight the desired application.
  5. Click Select.
  6. Choose in what state the applications will engage Caffeine under Apps trigger Caffeine mode.

Does keeping the system awake drain the battery?

Yes, naturally.

Especially high-resolution video playback — or, worse, rendering — on a brightly lit screen will consume ample amounts of power.
