How to modify the system default login background image?

  • 772

Following this, I added a couple of modified background images to the backgrounds collection. Now, I want to select a different background for the login screen. How do I do that?

UPDATE: Just tried David's solution on a fresh installation of Ubuntu 11.10. It seems like the file: /usr/share/applications/gnome-appearance-properties.desktop does no longer exist. Any idea on what I can use instead?

    Open the terminal and run the following commands

    sudo cp /usr/share/applications/gnome-appearance-properties.desktop /usr/share/gdm/autostart/LoginWindow

    Then logout, and you’ll see an Appearance window pop up. Change it to how you prefer it, then close it and login as usual.

    When you have logged in after finishing the customizing, run this command to prevent the Appearance window from opening at the GDM screen every time.

    sudo unlink /usr/share/gdm/autostart/LoginWindow/gnome-appearance-properties.desktop

    or

    If you want to install plymouth themes run the following command from your terminal

    sudo aptitude install plymouth-theme-*

    Now you can run the following commands to change login and plymouth screens

    sudo update-alternatives --config default.plymouth

gksu -u gdm dbus-launch gnome-appearance-properties
