Changing Background image for LightDM

[ScottyK]

Does the background image one selects to display on the logon screen have to be a certain size/file/directory? I've selected the image I want, and it shows up as a small icon on the setup menu for lightDM. However when I reboot, a white background is now display. Not my image, and not even the default Kubuntu background image.

Are you referring to Background image: on the Theme tab, or the actual background image when you are on the login screen?

[ScottyK]

The actual background when you log on.

Below is what my settings show. You can see (maybe!) the shuttle picture that I selected.

IIRC, that background image isn't used for the screen background (login wallpaper); it's used for the background of the user image.

[ScottyK]

Oh ok. How does one make a custom wallpaper for the logon screen?

[Snowhog]

Okay, I'm wrong. Not the first time. Won't be the last.

I just tested, and it does set the LightDM Login screen background. I selected a 1440x900 .png image, saved, and logged out and back in. That selected image was used as the screen background.

I took your cue and saved it as a png file, and moved it to /usr/share/wallpapers. Now it works!

Sweet. I was looking for a solution to this all afternoon. You'd think that would be something the dev would specify, "Must be in png format".

Anyway, thanks!
