Handler.sh permissions?

Question

Hi all,
I've been fiddling with my handler.sh file for ages, trying to get my hotkeys on my Thinkpad X40 to work. I've finally got to the stage where the action is recognised (i.e. the "logger" message shows up in /var/log/messages.log in the below cases). However, I can't get some actions to work.
For example:
button/screenlock*) # Fn+F3
logger "acpid: blank screen (Fn+F3) pressed; switching display off"
sleep 1 && xset dpms force off ;;
button/sleep*) # Fn+F4
logger "acpid: sleep button (Fn+F4) pressed; initiating pm-suspend"
/usr/sbin/pm-suspend ;;
In this case, the sleep button works, and I can suspend the computer. However I cannot blank the screen with Fn+F3, although when I am in a normal terminal I can execute the above command without sudo. xset is in /usr/bin/ however, and not /usr/sbin/. I have a variety of other commands that do not also exectute for other hotkeys (cpufreq-set etc), but I'm hoping someone can give a solution to this, and it will work for all of them!
Cheers,

Following on from the last bit ...
I'm still having the problem with, for example,
video/switchmode*) # Fn+F7
logger "acpid: Fn+F7 pressed, toggling screen"
case "$(xrandr -q | grep LVDS1)" in
*"+"*) ### LVDS1 is in use
case "$(/usr/bin/xrandr | grep VGA1)" in
"VGA1 connected (normal"*) ### VGA1 connected but not in use, so turn on in dual screen
logger "acpid: VGA1 now being used as second screen, above LVDS1"
/usr/bin/xrandr --output VGA1 --mode "1024x768" --above LVDS1;;
*"+"*) ### VGA1 is in use, so turn off LVDS1 and optimise VGA1
logger "acpid: LVDS1 switched off and VGA1 left on"
/usr/bin/xrandr --output LVDS1 --off
/usr/bin/xrandr --output VGA1 --auto
/usr/bin/xrandr --output VGA1 --preferred;;
*) ### VGA1 not connected
logger "acpid: external screen not found" ;;
esac;;
"LVDS1 connected (normal"*) ### LVDS1 connected but not in use, so turn off VGA1 and turn on LVDS1
logger "acpid: LVDS1 turned on, and VGA1 off"
/usr/bin/xrandr --output VGA1 --off
/usr/bin/xrandr --output LVDS1 --auto
/usr/bin/xrandr --output LVDS1 --preferred;;
*) ### if LVDS1 is not connected
logger "acpid: LVDS1 is not connected";;
which works fine as a separate script, but not as part of handler.sh. In saying that, it worked one time when I was fiddling round with it, but not again since. Given that it also worked before the last time I updated, do I maybe just need to change the permissions on the file or something similar?
