Set custom background

You can change the default desktop background to one that you want to use. For example, you may want to use a background with your company or university logo instead of the default GNOME background.

Set the default background

  1. Create the user profile which contains the following lines:



    local is the name of a dconf database.

  2. Create the directory /etc/dconf/db/local.d/ if it does not already exist.

  3. Create the key file /etc/dconf/db/local.d/00-background to provide information for the local database.


    # Specify the dconf path
    # Specify the path to the desktop background image file
    # Specify one of the rendering options for the background image:
    # Specify the left or top color when drawing gradients, or the solid color
    # Specify the right or bottom color when drawing gradients
  4. To prevent the user from overriding these settings, create the file /etc/dconf/db/local.d/locks/background with the following content:


    # Lock desktop background settings
  5. Update the system databases:

    # dconf update
  6. Users must log out and back in again before the system-wide settings take effect.
