/etc/acpi/handlers.sh (screen lock and suspend)

I'm trying to lock my screen with gnome-screensaver on suspend, but it doesn't. The script works as a normal user, but when run as root, like acpid would, I get:

/etc/acpi/actions/sleep.sh 
** Message: Failed to connect to the D-BUS daemon: Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken.

The script is:

#!/bin/bash

sleep 1 &&
gnome-screensaver-command -l &&
sleep 3 &&
sudo pm-suspend --quirk-s3-bios --quirk-s3-mode &&
exit

/etc/acpi

#!/bin/sh
# Default acpi script that takes an entry for all actions

# NOTE: This is a 2.6-centric script.  If you use 2.4.x, you'll have to
#       modify it to not use /sys
