Error while attempt to change login screen background picture

Question

Open a terminal and get root

sudo -i

(Type sudo password)

Allow the user lightdm to create a connection to the X server

xhost +SI:localuser:lightdm

Switch user to lightdm

su lightdm -s /bin/bash

Change the default background with a picture of your choice

gsettings set com.canonical.unity-greeter background '/foo/wallpaper.png'

i get this error :

**> (process:3178): dconf-WARNING **: failed to commit changes to dconf:

Error spawning command line 'dbus-launch --autolaunch=c50417a6888605aa39e81e4c56aa8bba --binary-syntax --close-stderr': Child process exited with code 1**

Here's the way of changing lightdm greeter background. It has been mentioned in the official ubuntu wiki. I've also put together a script that does the same thing, just lightly simpler. Let me know if you want complete answer posted here — Sergiy Kolodyazhnyy, Jan 29 '16 at 14:09

After switching to lightdm you should first issue this command:

gsettings set com.canonical.unity-greeter draw-user-backgrounds 'true'
