My laptop isn’t under my supervision most of the time. And I’d hate it if someone were to steal my SSD, or whole laptop even, when I’m not around. Is there a way to encrypt everything, but still keep the device in sleep, and unclock it without much delay. It’s a very slow laptop. So decryption on login isn’t viable, takes too long. While booting up also takes forever, so it needs to be in a “safe” state when simply logged out. Maybe a way that’s decrypt-on-demand?
I’m on Arch with KDE.
I can sleep “sleep”. All system components are still powered on at this stage, so it uses the most power. But at the same time it’s the quickest to get back into your system. All that’s really happening with sleep is that the screen turns off.
Then you have suspend. Laptops often first go to sleep but then suspend after a long period of inactivity to save battery.
Then you have hibernation. I don’t think this is used that often nowadays.
I have never met anyone refer to “screen off” as “sleep”.

The terms everybody else are using are: “sleep” = “suspend to RAM” = “S3” and “hibernation” = “suspend to disk”.
