I wanted to change the background for my login screen some time ago. So I followed the steps here: How do I change the wallpaper in LightDM?
But now I to set it back so that unity-greeter will have the same background as whatever user is logging in. The same page said to do these commands:
gsettings reset com.canonical.unity-greeter draw-user-backgrounds gsettings reset com.canonical.unity-greeter background
So I did and now I just have a purple screen when I am logging in. Once I hit Enter after submitting my password, my screen goes crazy and looks very distorted for a few seconds and then when I am logged in, my desktop background comes up.
How can I revert back to having unity-greeter draw the users backgrounds? Any help is appreciated.
