Lock screen wallpaper won't change?

[pancakesurprize]

Hey all. Apologies if this issue is caused by my own incompetence--I am still kind of new to all of this.

Basically my problem is that whenever I change my desktop wallpaper, the lock screen wallpaper won't change with it. Whenever I boot up my laptop, it shows a previously used wallpaper instead, only to return to the wallpaper that I had selected a little after login. Is there any way that I can fix this?

Thanks in advance.

Are you using the standard Ubuntu (with Unity) or any other flavor with a different desktop environment?

Thank you.

Now that we know we're dealing with Unity someone will be able to suggest something.

Hey mate.

Download and install Ubuntu Tweak and go to tweaks, logon screen. Unlock it and u can select option to use same wallpaper as desktop or a separate wallpaper.

sudo apt-get install ubuntu-tweak
