How do I add customized wallpapers so they appear in the dynamic unity greeter?
Here is what I am doing:
Right-click on desktop > select "Change Desktop Background" > under the "Look" tab select "Wallpapers" from the drop-down menu > click on the "+" button to add new wallpapers to the selection > browse to the wallpaper and click "open" ...
What happens then is that the "Wallpapers" section changes to the "Pictures Folder" section with the wallpaper being applied to the desktop background - However when I close the Appearance dialog and reopen it and go again to "Pictures Folder" my wallpaper is no longer there!!
- The Wallpaper should be added to the "Wallpapers" section and not to the "Pictures Folder" .... and
- The custom wallpaper should not disappear -- ever!
And, yes, this is a clean install not an upgrade ... and yes it's occurring on other Ubuntu 12.04 machines as well - all of the 3 I have here.
