I running Luna on Acer netbook AOD260 and I finally found a pattern:
pantheon-greeter works with these wallpapers: Lake McDonald, Lighthouse, morning, Temple and Tunnel
All of those wallpapers have slightly smaller height than other wallpapers in Luna i.e. they have
appropriate height for my netbook screen.
So I guess pantheon-greeter unable to adapt to wallpapers size.
