This is what I use to give myself a three second grace period between the
screen going blank and the lock kicking in. The scroll lock led was for
fun and cosmetics.

$ egrep '^xidle|^xlock' .Xresources
xidle.*.timeout: 300
xidle.*.delay: 99999
xlock.*.lockdelay: 3
xlock.*.startCmd: xset dpms 3; sleep 3; xset led named "Scroll Lock"
xlock.*.endCmd: xset -dpms; xset -led named "Scroll Lock"

I start xidle in my ~.xsession
