How to Change the Login Screen Wallpaper in Gnome 3.x Shell

In this article I’m going to tell you how to change the login screen wallpaper in Gnome 3.x Shell. I’m also going to provide a script that is capable of starting this for you, along with instructions on how to use it.

Changing the login screen wallpaper in Gnome 3.x Shell is easy. Just open up your terminal and enter the following commands:

xhost + -u gdm dbus-launch gnome-control-center

This will open up the Gnome Control Center. Click on background and change the background, then exit.

Alternatively you can run this script to open up the Gnome Control Center:

change_login.sh.tar.gz



Untar the script and run this command from the directory it was extracted to in order to make it executable:

chmod +x change_login.sh

Now you can double click on change_login.sh and it will ask you if you want to run it. Select run or run in terminal to use it.
