Here's the version of S2U2 I'm using, there is an updated version.

Once installed SR.
then go
Start-s2u2-s2u2 settings-general-lock when device wakes up "ON" , Lock when Screen is blank "OFF"

configure the rest as you see fit.

With these settings, power button starts s2u2 (locks screen) but does not lock the screen when the backlight turns off. it's pretty slick, power button tap and your all locked up.
