How to change login screen background?

[ballen]

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,
Bobby

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.
