You're wanting something that turns the screen off while idling at the console? Are you aware of physlock and vlock?
You've assigned the value 0 to the variable $done, and then not referenced it - remove that assignment. You initialise $i and increment it, but then you don't actually use it anywhere? Instead of "kill -18" and "kill -19", use "kill -CONT" and "kill -STOP" - it's more readable. Don't use backticks, use $(...) instead, as it nests better. Your usage states to run "./ssvr.sh ssvr.sh" and then you use "kill ... `pidof $1`". This seems to imply that you're not aware of the $$ variable, which is the PID of the current shell. Most of these are simple fixes which shellcheck.net can advise you on. If possible, you should find a plugin for the editor you're using which can give you realtime shellcheck advice :)
