Ensure that your background image is appropriately sized for the screen that you are using. You can check your screen geometry as follows: $ xdpyinfo | grep -B1 dot Then invoke gnome-control-center as user gdm as follows: In this post I show you a simple way to add preference persistence to your Cinnamon or GNOME Shell extension using JSON. |
