Screen goes blank after 30 seconds when apparently it "never" should
I'm trying to set up my screen to stay always on, but when I press Super+L, I want to to get locked, go blank after a while, and ask for the password when I move the mouse or touch a key. I haven't been able to find the right settings to do so. With the settings below, I expect the screen to never go blank by itself. However, it goes blank after 30 seconds.
