Comment 4 for bug 569202

Addition to my comment #3

I think the guess of the original reporter (as repeated in comment #2) as "WhiteOrchid.jpg replaced warty-final-ubuntu.jpg" (it should be .png, I suppose) which is found in /usr/share/gconf/defaults/16_ubuntu-wallpapers is not valid. I don't have the Lucid machine I confirmed the bug with me right now but checking from my Ubuntu Karmic installation:
* My login screen was and is what Karmic default is which is obviously not the warty-final-ubuntu.png image
* The first line of my /usr/share/gconf/defaults/16_ubuntu-wallpapers reads as:
/desktop/gnome/background/picture_filename "/usr/share/backgrounds/warty-final-ubuntu.png"
* Even there's a reference to warty-final-ubuntu.png, which is indeed in /usr/share/backgrounds, neither my login screen theme nor desktop background have never been and is not at the moment "warty-final-ubuntu.png" image
* When I delete that line
/desktop/gnome/background/picture_filename "/usr/share/backgrounds/warty-final-ubuntu.png"
from the file
/usr/share/gconf/defaults/16_ubuntu-wallpapers
and save the file and restart x; my login screen theme is still the Karmic default; and my preferrred user-set desktop background is still the same
* I don't know if that line (or even that file completely) has any use but seems that it is not related with the login screen theme
* In Lucid the image used for the login screen can be found in wallpaper choises as well (actual source files may be different; images are similar/same) but in Karmic the default login screen image is even not found as a desktop background choice
* And I even don't know / can't find where that Karmic login screen image lies and what the filename is
* As a result; Gnome login screen or its Ubuntu modification gets that image from somewhere but not from /usr/share/gconf/defaults/16_ubuntu-wallpapers
* As I stated in comment #3 community have difficulties to modify the login screen theme from Karmic on and its not that easy as to change a line in a file lying in /usr/share/gconf/defaults. In my opinion its not good to hide such files and preferences to some mysterious places and not to document them, but this is beyond the scope of this bug
* As a result, what I confirm is: Installing that package changes the the login screen theme to that image, as I said in comment #3
* In this sense, a modification for this bugs name maybe usefull, if the issue has nothing to do with "warty-final-ubuntu.jpg" [.png ???]
