3)I change my desktop wallpaper to a picture I have imported from my mobile phone or from the internet, Unity greeter should show me my desktop wallpaper when I select my User account ready to log in.

4) Instead, Unity Greeter shows me the default Ubuntu wallpaper.

Oh, I wanted to add that Installing another Wallpaper pack "sudo apt-get install ubuntu-wallpapers-"releasename" and selecting one of those wallpapers still reverts back to the default wallpaper on the login screen.

Status changed to 'Confirmed' because the bug affects multiple users.

I have this bug too on my 14.04.1 LTS, login does not show my wallpaper as it should, it shows default Ubuntu wallpaper, lockscreen correctly shows my wallpaper but login does not, it is a fresh installation and fully updated.

I am also seeing this on Ubuntu 15.04. Oddly enough it worked for me on Ubuntu 14.04 though.
