I installed Xubuntu 22.04 and applied a Gruvbox theme I downloaded from the internet.
Now, from the application menu, when I press "Lock Screen," a login screen comes up that matches my theme in appearance decently; it had the same wallpaper as my desktop, and the colorscheme of the GUI elements also matched. However, when I press "Log Out...", the login screen there looks different; it was the same as the first time I saw it after installing Xubuntu. Is this normal? How can I make it look like the login screen from "Lock Screen"?
