Xscreensaver does not activate by default on resume unless:
1. The time interval between suspend and resume is longer than xscreensaver
timeout.
2. There is an explicit script in /etc/pm/sleep.d which locks thescreen on
resume. For example:
#!/bin/bash
pid=$(pidof -o %PPID /usr/bin/xscreensaver)
case $1 in
	hibernate)
		;;
	suspend)
		if [ "x$pid" != "x" ]; then
			x_owner=$(/bin/ps -e u | /bin/grep xscreensaver \
                                  | /bin/grep $pid | \
                                  /bin/awk '{print $1}')
                        /bin/su $x_owner -c \
                         "/usr/bin/xscreensaver-command -lock &> /dev/null"
                fi
		;;
	thaw)
		;;
	resume)
		;;
	*)
		exit 1
		;;
esac

Personally I always prefer to have such a script to prevent unauthorized
access.
