I noticed that the login screen that I get when the system first boots up is different from the login screen I see after I resume from suspend. I'm wondering if it is possible to get the same login screen that I saw when it first booted up as the one I get when I resume the system from suspend. I think the first boot login one is called LightDM greeter or something, not sure about the second one.
Then install Lightlocker
