Sleep can be handled by local script or program. Suspend hook is the bigger issue.
Want suspend to call the locker.

Locking: Remaining issue as of 2019/06/27:

automatic suspend does not trigger the screen to lock.
xscreensaver is used to sleep/lock the screen & suspend the machine by-timeout, and works as expected.
Automatic suspend (lid-close,power-button) does not trigger any locking device, so the desktop is not secured when the lid is openned.

here's a lock using i3lock, with screen dim support:

#!/usr/bin/env bash

Only exported variables can be used within the timer’s command.

export PRIMARY_DISPLAY=”$(xrandr | awk ‘/ primary/{print $1}’)”

Run xidlehook

xidlehook
# Don't lock when there's a fullscreen application
–not-when-fullscreen
# Don't lock when there's audio playing
–not-when-audio
# Dim the screen after 60 seconds, undim if user becomes active
–timer normal 60
‘xrandr –output “$PRIMARY_DISPLAY” –brightness .1’
‘xrandr –output “$PRIMARY_DISPLAY” –brightness 1’
# Undim & lock after 10 more seconds
–timer primary 10
‘xrandr –output “$PRIMARY_DISPLAY” –brightness 1; i3lock’
‘’
# Finally, suspend an hour after it locks
–timer normal 3600
‘systemctl suspend’
‘’

#!/usr/bin/env bash
