Testing with lightdm-gtk-greeter, I do get the expected xprops:
ESETROOT_PMAP_ID(PIXMAP): pixmap id # 0xe00001
_XROOTPMAP_ID(PIXMAP): pixmap id # 0xe00001
And it works fine, i.e. no grey background there.
I'm testing with the default background, i.e.
$ gsettings get org.gnome.desktop.background picture-uri
'file:///usr/share/backgrounds/warty-final-ubuntu.png'

Lightdm doesn't have such code. I don't know if it's obligatory to have code for those xprops or not.
Thank you Alberts!
