Changing the LightDM background in FunOS is a simple process that can help you personalize your login screen. Follow the steps below to update the background image to one of your choice.

Step 1: Open Terminal

To begin, open the Terminal application in FunOS using one of the following methods:

• Click Menu in the bottom-left corner and select Terminal.
• Click the Terminal icon in the Tray.

Step 2: Add LightDM to Your User Group

To ensure you have the necessary permissions to change the LightDM background, add the LightDM user to your user group. Enter the following command in the terminal:

You will need to enter your password to execute this command. Once completed, this step ensures that lightdm has the required access rights.

Step 5: Select a New Background Image

Once authenticated, follow these steps to select a new background image:

1. In the LightDM GTK Greeter settings window, locate the Image option.

2. Click the folder icon to the right of the Image option.

By default, the /opt/artwork/wallpaper folder will open. Here you can select from the default images available in FunOS.

If you prefer to use a custom image stored in your home directory, follow these additional steps:

After selecting your desired image:
