i3lock: How to enable auto-lock AFTER wake up from suspend? [SOLVED]

Hello cee and thanks for your helping answer!

1) Unfortunately

exec --no-startup-id xautolock -time 5 -locker 'i3lock -c 000000' &

still causes a white lock-screen.

2) I deployed the i3exit.sh in ~/.i3 and modified my i3-config. Pressing the specified button calls the menu correctly. Lock works, but it seems that everything that calls systemctl doesn't work.

#!/bin/bash
############################################################
#
############################################################
function lock {
    i3lock -c 000000
}
case "$1" in
    lock)
        lock
        ;;
    logout)
        i3-msg exit
        ;;
    suspend)
        lock && systemctl suspend
        ;;
    reboot)
        systemctl reboot
        ;;
    poweroff)
        systemctl poweroff
        ;;
    *)
        echo "Usage: $0 {lock|logout|suspend|reboot|poweroff}"
        exit 2
esac

exit 0

Well, my distri uses a python-script for the logout/susp/exit-functions:

#!/usr/bin/env python

pygtk.require('2.0')
