How to Disable Sleep When You Close the Laptop Lid in Ubuntu

Have you ever connected your Ubuntu laptop to an external monitor, SSH session, server, or other device and discovered that everything stops working as soon as you close the laptop lid?

By default, Ubuntu may suspend the system when the laptop lid is closed. This is useful for normal laptop use because it saves battery and reduces power consumption. However, it can be inconvenient when you want your laptop to continue running with the lid closed.

For example, you may want to use your Ubuntu laptop as:

A home server
An SSH server
A development machine
A media server
A Docker/Kubernetes node
A machine connected to an external monitor
A remote desktop system
A background download or automation system

Fortunately, Ubuntu allows you to change the lid-close behavior through systemd-logind.

What Happens When You Close the Laptop Lid?

On a typical Ubuntu installation, closing the lid triggers an action handled by systemd-logind.

The default behavior is commonly:

HandleLidSwitch=suspend

This means:

When the laptop lid is closed, suspend the system.

We can change this behavior to:

HandleLidSwitch=ignore

This tells Ubuntu:

When the lid is closed, do nothing.

The laptop will therefore continue running even though the physical lid is closed.

Method: Disable Suspend on Lid Close

Step 1: Open the Terminal

Press:

Ctrl + Alt + T

Alternatively, search for Terminal from the Ubuntu application menu.

Step 2: Open the systemd Login Configuration

Run:

sudo nano /etc/systemd/logind.conf

You will be asked for your administrator password.

The file contains configuration options controlling various login and power-management behaviors.

Step 3: Find the Lid Switch Setting

Look for:

#HandleLidSwitch=suspend

The # means that the line is commented out.

Change it to:

HandleLidSwitch=ignore

If the line already exists without #, simply change:

HandleLidSwitch=suspend

to:

HandleLidSwitch=ignore

Your configuration should look like:

[Login]
HandleLidSwitch=ignore

If [Login] already exists, don't create another [Login] section.

What About External Power?

If you primarily use your laptop while it is connected to a charger, you can also configure the external-power behavior:

HandleLidSwitchExternalPower=ignore

This can be useful when the laptop is being used as a workstation or server while connected to AC power.

For example:

[Login]
HandleLidSwitch=ignore
HandleLidSwitchExternalPower=ignore

What About a Dock or Docking Station?

If you use your Ubuntu laptop with a docking station, you may also encounter the docked-state setting.

You can configure:

HandleLidSwitchDocked=ignore

A configuration for a laptop that should remain running regardless of lid/power state could therefore be:

[Login]
HandleLidSwitch=ignore
HandleLidSwitchExternalPower=ignore
HandleLidSwitchDocked=ignore

However, you don't necessarily need all three settings. Start with HandleLidSwitch=ignore and add the others only if your particular setup requires them.

Step 4: Save the Configuration

If you're using Nano:

Press Ctrl + X
Press Y to confirm saving
Press Enter

Your configuration has now been saved.

Step 5: Apply the Changes

You can restart systemd-logind:

sudo systemctl restart systemd-logind

Alternatively, and often more conveniently on a desktop/laptop system, reboot Ubuntu:

sudo reboot

A reboot ensures that the new configuration is loaded cleanly.

Important: Restarting systemd-logind can affect active graphical/login sessions on some systems. If this is an important workstation or remote machine, a planned reboot may be the safer option.

Test the Configuration

After Ubuntu starts again, close the laptop lid.

If everything is configured correctly, Ubuntu should remain running instead of suspending.

You can test this by:

Connecting through SSH
Checking a running process
Accessing a web server
Connecting through Remote Desktop
Monitoring a Docker container
Checking a file transfer
Accessing an external monitor

For example, from another computer:

ssh username@ubuntu-ip

If the connection continues working after closing the lid, your Ubuntu machine is successfully remaining active.

Useful Configuration Examples

Normal Laptop — Suspend on Lid Close

The default behavior can be represented by:

HandleLidSwitch=suspend

This is appropriate if you want the laptop to save power when you close the lid.

Laptop Server — Keep Running

For a laptop being used as a server:

HandleLidSwitch=ignore

This prevents lid closure from triggering suspend.

Laptop Used as a Docked Workstation

If you frequently connect the laptop to a charger, monitor and dock:

HandleLidSwitch=ignore
HandleLidSwitchExternalPower=ignore
HandleLidSwitchDocked=ignore

Why Would You Want to Disable Lid Sleep?

There are several practical situations where this configuration is useful.

1. Using an External Monitor

You may want to close the laptop lid and use only your external display.

Without changing the lid behavior, Ubuntu may suspend the laptop.

2. Running a Home Server

An old laptop can make an excellent low-power home server.

You could run:

Ubuntu Server
Docker
Kubernetes
PostgreSQL
Web applications
File servers
Home automation
Media services

Disabling lid suspension allows the laptop to continue operating with the lid closed.

3. Remote Access

If you use:

SSH
RDP
VNC
RustDesk
Other remote-management tools

you may want the machine to remain available even when the lid is closed.

4. Long-Running Jobs

Developers and administrators may run:

Docker containers

Build jobs

Data-processing tasks

Machine-learning workloads

or other long-running processes.

Suspending the laptop could interrupt or pause these workloads.

Check Whether the Configuration Is Active

You can inspect the current configuration with:

grep -i "HandleLidSwitch" /etc/systemd/logind.conf

You may see:

HandleLidSwitch=ignore

You can also inspect the effective logind configuration:

loginctl show-logind

On systems where the command exposes the relevant properties, look for values such as:

HandleLidSwitch=ignore

Important: Disabling Sleep Is Not the Same as Disabling the Screen

Changing:

HandleLidSwitch=ignore

doesn't necessarily mean that the display will remain active.

The laptop can continue running while its internal display is turned off because the lid is closed.

This is generally desirable when using the machine as a server or with an external monitor.

Important Power and Heat Considerations

Keeping a laptop running with the lid closed isn't always ideal.

The display may turn off, but the CPU, storage, networking hardware and other components can continue operating.

On some laptop designs, closing the lid can also reduce airflow around the keyboard or cooling system.

Therefore:

Make sure the laptop has adequate ventilation.

Avoid placing a running laptop:

Inside a closed cabinet
Under blankets
On a soft bed
In an area where air vents are blocked

If you're converting an old laptop into a permanent server, consider placing it on a hard, well-ventilated surface.

What If It Still Suspends?

If changing logind.conf doesn't work, don't immediately assume the configuration is wrong.

Several factors can influence power management, including:

Desktop-environment settings
GNOME power-management behavior
Docking state
External power configuration
systemd-logind inhibitors
Distribution-specific configuration
Other power-management software

First verify your configuration:

grep -i "HandleLidSwitch" /etc/systemd/logind.conf

Then reboot and test again.

You can also check the system journal:

journalctl -u systemd-logind

This can help identify whether systemd-logind is processing the lid event.

Is It Safe to Disable Lid Suspend?

Generally, yes, if you understand the consequences.

The configuration does not disable the laptop's ability to suspend manually. It changes what happens specifically when the lid is closed.

You should, however, consider:

Battery consumption
Heat generation
Ventilation
Accidental overheating
Whether the laptop is connected to AC power
Whether you actually need the machine running continuously

For a laptop being used as a home server, keeping it connected to AC power and ensuring good ventilation is usually more appropriate than relying on battery power.

Quick Command Summary

Edit the configuration

sudo nano /etc/systemd/logind.conf

Set lid close to do nothing

HandleLidSwitch=ignore

Optional external-power setting

HandleLidSwitchExternalPower=ignore

Optional docked setting

HandleLidSwitchDocked=ignore

Restart logind

sudo systemctl restart systemd-logind

Or reboot

sudo reboot

Check your configuration

grep -i "HandleLidSwitch" /etc/systemd/logind.conf

Final Thoughts

Ubuntu is flexible enough to turn an ordinary laptop into a surprisingly capable server or always-on Linux workstation.

If you frequently use your Ubuntu laptop with an external monitor, SSH, Remote Desktop, Docker, Kubernetes or other long-running services, changing the lid-close action from:

suspend

to:

ignore

can make the machine much more convenient to operate.

The key configuration is simply:

HandleLidSwitch=ignore

Just remember that "ignore" means Ubuntu will not automatically suspend because you closed the lid. It does not mean the machine consumes no power or generates no heat.

For a server-style setup, always prioritize proper ventilation, reliable power and appropriate security.

One-Line Takeaway

Want your Ubuntu laptop to keep running after you close the lid? Set HandleLidSwitch=ignore in /etc/systemd/logind.conf, then reboot and test it.
