ubuntu 10.04 Lucid Lynx I can confirm this as well.
Story: My brother-in-law had Ubuntu 9.10 - fresh installed by me; dual boot with Windows XP. I web updated Ubuntu part of it to 10.04 Lucid. I installed 3 or 4 additional wallpaper packages from the repositories - one of them was "ubuntu-wallpapers-extra". Lucid's original login window's theme changed to a flower image. There were reports that changing GDM is very hard after Ubuntu 9.10 -if it is not impossible. So I didn't try much to alter it. I also didn't try to uninstall those wallpaper packages one by one to check for the defective one. By eye control I decided that the image is WhiteOrchid.jpg being among the wallpapers. I removed WhiteOrchid.jpg from the wallpapers directory (most probably it was /usr/share/backgrounds) and the background of the login window became plain white (no theme, I mean). I copied WhiteOrchid.jpg to that directory again. It reappeared as the login window theme. I told my brother-in-law that he should use that for some time, for some reason which is hard to tell. I'm still on 9.10 Karmic but if developers ask for gathering info from my brother-in-law's machine which we experienced the issue; I will be happy do that. -- WhiteOrchid.jpg replaces warty-final-ubuntu.jpg as login wallpaper https://bugs.launchpad.net/bugs/569202 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
