The theme is shown when turning on my laptop but not when closing and opening the lid of the laptop

As seen in the title, I have that problem. When I close and open the lid of the laptop what appears to be the default xfce greeter appears.

I couldn't find a way to take a screenshot of this, but I did find an image on google that shows something very similar to what I get when I close and open the lid.
