How to change login screen background?

Hey guys,

Sorry if this is not the right place for this, but I was just wondering how I can go about changing the Login screen background? - I assume I can just replace an image file somewhere on the file-system?

Also, just so I know does MATE on Ubuntu 14.04 use MDM or GDM?

Thanks in advance,

It’s actually using lightdm-gtk. To change the background for the login change “background =” line in the file “/etc/lightdm/lightdm-gtk-greeter-ubuntu-mate.conf” and make it point to whatever image you want to use (for example: “background = /usr/share/backgrounds/41621_anime_scenery.jpg”). I usually copy the image to “/usr/share/backgrounds” and make sure the permissions give everyone read access at least.

Thanks very much for your reply, I’ll give that a go :smiley:

2020 and now the first item in the Control Panel under Administration is "Login Window". Very user friendly.

It shows you the path where the images are coming from if you want to add one of your own. Only catch could be making sure everybody has permission to read the file.
