Change Lid Close Behavior in Ubuntu 20.04, 22.04 & 24.04 Updated

Last updated: April 28, 2024

This simple tutorial shows how to change the action (e.g., power off, hibernate, do nothing, or lock) when laptop lid is closed in Ubuntu 20.04, Ubuntu 22.04, and Ubuntu 24.04, while it suspends Ubuntu by default.

NOTE: This tutorial is also tested and works in Ubuntu 22.04, and Ubuntu 23.10 with default GNOME desktop environment.

Dconf editor offers options to change the action to take when the laptop lid is closed on AC or power, but it doesn’t work!

So far as I know, you can edit the logind.conf file to change the action. And it should work on all Ubuntu desktop, server, and flavors.

1.) Open terminal (press Ctrl+Alt+T on Gnome) from your system application menu. When it opens, run command:

sudo gedit /etc/systemd/logind.conf

Type user password (no asterisk feedback) and hit Enter. For Ubuntu 24.04, replace gedit in command with gnome-text-editor or nano command line text editor depends on your desktop environment.

2.) When the file opens, find out the line #HandleLidSwitch=suspend and change it to one of following :

  • HandleLidSwitch=lock – lock when lid closed.
  • HandleLidSwitch=ignore – do nothing, some laptops will disconnect Wi-Fi.
  • HandleLidSwitch=poweroff – shutdown.
  • HandleLidSwitch=hibernate – hibernate Ubuntu.

NOTE: hibernation feature does NOT work out-of-the-box in Ubuntu, you have to enabled it first if need.

3.) Set different lid close action when running on power supply.

For choice, you can also uncomment ‘HandleLidSwitchExternalPower=suspend‘ by removing # at its beginning, and change the value to lock, ignore, poweroff, or hibernate.

So the rule in step 2.) only works when your laptop is running on battery. While, this step will take effect when running on AC power supply.

4.) Finally apply changes by running command (For old 14.04 with init, use sudo restart systemd-logind instead):

systemctl restart systemd-logind.service

For Ubuntu 22.04 and higher, the command will log you out, and break next login. So, you may just restart your computer instead to apply change.

Note you have to do previous steps every time you want to change the action. And ‘Suspend when laptop lid is closed‘ option in Gnome Tweaks will no longer work before you comment (add # at the beginning) the line in /etc/systemd/logind.conf.

[Quick Tip] Enable Textual File Path Entry in Ubuntu 20.04

Last updated: May 9, 2020

gnome shell

This quick tip is going to show you how to get a textual location entry in the default Nautilus file browser in Ubuntu 20.04.

For temporary use, you can get the current files or folders’ path by simply pressing Ctrl+L on keyboard.

The default path bar becomes a location entry after pressing Ctrl+L, then you can copy and paste it for any use.

To let Nautilus display textual path entry for the location bar permanently:

Instead of the path-bar, you can always use a textual input entry for the location toolbar, by running following command in terminal:

  • Press Ctrl+Alt+T to open terminal and run command: 
    gsettings set org.gnome.nautilus.preferences always-use-location-entry true

  • And you can restore change via command: 
    gsettings reset org.gnome.nautilus.preferences always-use-location-entry

Alternatively, use a graphical tool Dconf Editor, install it via Ubuntu Software, by navigating to ‘org/gnome/nautilus/preferences’

That’s it. Enjoy!

Change Lock Screen Background Wallpaper in Ubuntu 24.04 | 22.04

Last updated: November 18, 2024

The lock screen background option was removed from settings since Ubuntu 20.04. Now, it uses desktop wallpaper with blur effect as the background for the lock screen.

For those who still want to change the lock screen background, then there’s an extension that supports GNOME from version 3.26 to 47. Meaning all current Ubuntu releases, Fedora, and other Linux with GNOME are supported.

NOTE: This tutorial only works for the default GNOME Desktop!

Option 1: Use Extension Manager

For Ubuntu 22.04, Ubuntu 24.04 and higher, there’s a popular “Extension Manager” app available in system repository for install and manage extensions in default GNOME desktop.

1. First, launch App Center or Ubuntu Software. Then, search for and install the “Extension Manager” app:

Install Extension Manager in Ubuntu Software/App Center

2. Then, launch the “Extension Manager” app, navigate to “Browse” tab. Finally, search & install the “lock screen background” extension.

Tips: Try switching the filter if it does not show you that extension. Or, use Option 2 to install it using web browser.

3. Once installed, switch back to “Install” tab, and click on the setting icon for that extension. Finally, click on “Browse” button in pop-up dialog and choose an image file for the login background.

Option 2: Use web browser

Extension Manager is not available in system repository for old Ubuntu 20.04 and earlier. In the case, you may use your web browser to install the extension.

1.) Open terminal by pressing Ctrl+Alt+T on keyboard. When it opens, run command to install the agent package as well as Gnome Extensions app:

sudo apt install chrome-gnome-shell gnome-shell-extension-prefs

2.) Then open your web browser (e.g., Firefox), and go to the link button page:

Lock Screen Background in EGO

Finally, use the ON/OFF toggle to install the extension.

Don’t see the toggle switch? Try clicking the link text “click here to install browser extension” and follow the pop-ups to install the browser extension. Then, refresh the page.
shell browser extension

3.) Finally, launch GNOME Extensions app or Gnome Tweaks > Extensions, go to the extension settings page, and finally set a picture for lock screen background.

That’s it. Enjoy!

Firefox 76 Released with Audio Worklets Support

Last updated: May 5, 2020

Mozilla Firefox 76 was released today with improved online account protections and Zoom support.
