Laptop optimization

This ensures your laptop stays awake with the lid closed, maintains a stable network connection and boots quickly by ignoring unused network interfaces.

  1. Lid and sleep configuration

    Section titled “Lid and sleep configuration”

    These steps prevent the system from suspending or shutting down when the lid is closed or the power button is pressed.

    1. Open logind config

      Section titled “Open logind config”
      Terminal window
      sudo nano /etc/systemd/logind.conf

    2. Update config

      Section titled “Update config”

      Update the following lines to ignore to keep the system awake.

      /etc/systemd/logind.conf
      HandleSuspendKey=ignore
      HandleLidSwitch=ignore
      HandleLidSwitchExternalPower=ignore
      HandleLidSwitchDocked=ignore

    3. Restart logind

      Section titled “Restart logind”
      Terminal window
      sudo systemctl restart systemd-logind

  2. Disable system-wide sleep

    Section titled “Disable system-wide sleep”

    To prevent the kernel from attempting to sleep even if triggered by software, create a “no-sleep” override.

    1. Create nosuspend config

      Section titled “Create nosuspend config”
      Terminal window
      sudo mkdir -p /etc/systemd/sleep.conf.d/ && sudo nano /etc/systemd/sleep.conf.d/nosuspend.conf

    2. Add config

      Section titled “Add config”
      /etc/systemd/sleep.conf.d/nosuspend.conf
      [Sleep]
      AllowSuspend=no
      AllowHibernation=no
      AllowSuspendThenHibernate=no
      AllowHybridSleep=no

    3. Reload daemon

      Section titled “Reload daemon”
      Terminal window
      sudo systemctl daemon-reload
