I am quite lost on how to set user-specific background. There does not seem to be many resources on this matter.

Setting background from gnome-control-center does not work.

org.gnome.settings-daemon.plugins.background is set to true.

How do I set the user background for the lightdm login? Do I need to install another app to change backgrounds? Does feh affect such background choices?

(How could I get answers on these questions? Do I have to specify something? Anyone?)

It depends on the Greeter you are using. For instance. If you are using gtk-greeter you can use the main config:

Just look for background option in the /etc/lightdm/lightdm-gtk-greeter.conf file and set the filepath of your desired background image.

You can get more info here: https://github.com/canonical/lightdm

  • The problem is, I want to set the user-specific background, not a global one. I do not want to dictate the screen.

  • I'm not sure if I understand you. The greeter background is shown before you choose a user. So... How can be customised for the user if you haven't pick up one already. Do you wan't a dynamic background ? One that change depending on the selected user ?

  • What is a user background, then? I saw it in the e.g. lightdm slick greeter settings.
