Thank you for the bug report Rick. There is a long standing known issue: user wallpapers, if stored in a non world readable directory, are not visible to the greeter. That's bug #928553. The reason is that only the URL is shared (to not "leak" private infos), so the greater (which runs as another user) needs to be able to read the file to display it
Is the directory the image is stored in world readable? Not sure that's the case there though, since you seem to do twice the same steps and that should lead to the same directory to be used/result if you run "gsettings get org.gnome.desktop.background picture-uri", does it list the correct image? ** Package changed: lightdm (Ubuntu) => unity-greeter (Ubuntu) ** Changed in: unity-greeter (Ubuntu) Status: Confirmed => Incomplete -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to unity-greeter in Ubuntu. https://bugs.launchpad.net/bugs/1128492 Title: wallpaper not updating Status in “unity-greeter” package in Ubuntu: Incomplete Bug description: Steps: 1. Find a wallpaper image on the web in firefox 2. Right click and choose Set as Desktop Background 3. Log out, notice that it uses the new background in the greeter for that user, as expected 4. Login again 5. repeat #2 with a different image 6. Log out, note that the backgorund is the background set in #2, not the one set in #5 I even went and renamed the wallpaper image and put it in my Pictures directory. Then I set the background image with the settings tool. The image still did not update in the greeter.
