In august i wrote a post about hibernation on linux, Linux hibernation in just 4 steps.

If you want to add screen lock support in resume, you have to create a custom script.

Hibernation’s scripts run in reverse numeric order, so you have to use 00 (double zeros) in the name of your custom script, telling resume process to lock screen at the end.

In my case, i wrote a super simply bash script to slock my screen. I am the only user of my laptop so the bash script is extremely dammy and does only one thing, take a look:

/usr/lib/pm-utils/sleep.d/00lock

#!/bin/bash

case $1 in
	hibernate)
		# not required.
		su ebal -c slock &
	;;
	suspend)
		# not required.
	;;
	thaw)
		# not required.
	;;
	resume)
		# not required.
	;;
	*) exit $NA
	;;
esac

You should replace ebal with your user name and slock with your screen lock program.
Alternative commands against slock are:

• xscreensaver-command –lock
• gnome-screensaver-command ––lock
• xlock
