How To Change Lock Screen Wallpaper on Ubuntu 20.04 LTS

Ubuntu 16

Ubuntu 20.04 LTS, also known as Focal Fossa, is a popular Linux distribution that offers a high degree of customization. One of the areas where users often want to express their individuality is the lock screen wallpaper. However, in Ubuntu 20.04 LTS, the lock screen and login window have been combined into a single window, and the lock screen uses a blurred version of the desktop wallpaper. This change is by design and is considered normal behavior.

Despite this, there is a workaround available for those who want to customize their lock screen wallpaper. This involves installing an extension called “Lock screen background”. In this article, we will guide you through the process of changing your lock screen wallpaper on Ubuntu 20.04 LTS using this extension.

In this command, sudo gives you administrative privileges, apt is the package handling utility in Ubuntu, and install is the command to install a new package. gnome-shell-extensions is the package we want to install.

Installing the “Lock screen background” Extension

Once you have installed GNOME Extensions, you can now install the “Lock screen background” extension. To do this, visit the GNOME Extensions website and search for “Lock screen background”. Click on the extension and toggle the switch to “ON” to install it.

In the settings window, you can choose the image you want to set as your lock screen wallpaper. Click on the “Select Image” button, navigate to the image you want to use, and click “Open”. Once you have selected your image, close the settings window. Your lock screen wallpaper should now be set to the image you selected.

Conclusion

With this extension, you can easily customize your lock screen wallpaper to suit your preferences.
