On earlier versions of Ubuntu, there were tools that allowed you to change the login screen just the same as your wallpaper. On the latest versions, this ability has been somewhat obscured, but it’s still possible.

1 Decide on an image. Before you can change the screen, you need to decide on a picture. You can use one of the predefined Ubuntu images (they’re not bad, actually), or use any picture you wish. If you’re going to use one of Ubuntu’s images, skip step 3.

2 Log in as root. You need root privileges to change these settings. If you’re an administrator on your system, you can run on the command line sudo su root and provide your password to login as root.

3 Place the image in the /usr/share/backgrounds folder. First, place the picture in your Pictures folder. Then open a command line and type cp /home/(your user name)/Pictures/(full name of the picture file) /usr/share/backgrounds/(full name of the picture file). This places the image in the backgrounds folder, and makes it readily available to you in the wallpaper menu.

4 Place a link to the Gnome Appearance util in /usr/share/gdm/autostart/LoginWindow. Type cp /usr/share/applications/gnome-appearance-properties.desktop /usr/share/gdm/autostart/LoginWindow. Everything in this folder is run when the login screen is displayed, including the desktop properties for the login screen.

5 Change the file permissions for the link. Run chmod 444 /usr/share/gdm/autostart/LoginWindow/gnome-appearance-properties.desktop. This allows all users to read the link.

9 Change other options. What’s cool about being able to do this is you can change other settings, too. If you want the login screen to use your window borders and controls, you can change those settings.

11 Delete the link. Now that you’ve changed the settings, you need to delete the link so the options don’t appear every time you boot up. Run sudo rm /usr/share/gdm/autostart/LoginWindow/gnome-appearance-properties.desktop.
