I was trying to change this picture, and forget the name of the background.

Tried warty-final-ubuntu.png and warty-final-ubuntu.jpg but no use.

The name is: warty-final-ubuntu.png and it is inside /usr/share/backgrounds.

It is called warty-final-ubuntu.png just like you said but if you are searching for it I don't think it will show up since it is in usr folder. It is in filesystem/usr/share/backgrounds Also I don't think you can change it as I can't put any other images in that folder or rename one in it already.

I used gksu nautilus /usr/share/backgrounds and deleted it. Put another image with the same name. The image under the login screen disappeared. I downloaded the image again and placed to same location (renamed as warty-final...png). Still no images. Thanks for replies. Thought, the problem is about the name. But not, I think there is something different that I can not guess. – Hilmi Erdem KEREN Apr 9 '12 at 15:27
With Ubuntu Tweak you can choose the login screen background. To install paste this at a terminal: sudo apt-add-repository ppa:tualatrix/ppa ; sudo apt-get update ; sudo apt-get install ubuntu-tweak See a picture here: and more informatione here: – desgua Apr 9 '12 at 15:33
As I said, I am using 12.04 beta, Ubuntu Tweak is already installed in my OS. But the problem is that, Under the Login Theme Tab, There is "login screen logo" with a button, which has no image in it. There is no background or option related information. – Hilmi Erdem KEREN Apr 9 '12 at 15:40
Ups, it seems my header is edited. Sorry. Let me repeat, I am using 12.04 beta :) – Hilmi Erdem KEREN Apr 9 '12 at 15:41
Can you post a screenshot? Can't you click over where it was supposed to be the image background? – desgua Apr 9 '12 at 16:26

I fixed the problem using

sudo apt-get remove ubuntu-wallpapers && sudo apt-get install ubuntu-wallpapers && sudo apt-get install ubuntu-desktop && sudo apt-get install ubuntu-artwork

Thanks for any replies.
