Power Management Systemd & ACPI

Question

Hi,
I am having a lot of trouble configuring my power management. I basically want my monitor to go off  when I close my lid and disable suspend completely.
Since the time I have switched over to systemd, this has become a nuisance.
Following are my configuration files:
/etc/acpi/handler.sh
#!/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
#minspeed=`cat /sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_min_freq`
#maxspeed=`cat /sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_max_freq`
#setspeed="/sys/devices/system/cpu/cpu0/cpufreq/scaling_setspeed"
#set $*
case "$1" in
button/power)
#echo "PowerButton pressed!">/dev/tty5
case "$2" in
PBTN|PWRF) logger "PowerButton pressed: $2" ; poweroff ;;
*) logger "ACPI action undefined: $2" ;;
esac
button/suspend)
# sudo pm-suspend
button/sleep)
case "$2" in
SLPB) echo -n mem >/sys/power/state ;;
*) logger "ACPI action undefined: $2" ;;
esac
ac_adapter)
case "$2" in
AC|ACAD|ADP0)
case "$4" in
00000000)
echo -n $minspeed >$setspeed
#/etc/laptop-mode/laptop-mode start
00000001)
echo -n $maxspeed >$setspeed
#/etc/laptop-mode/laptop-mode stop
esac

case "$4" in

esac

esac
button/lid)
case $(cat /proc/acpi/button/lid/LID/state | awk '{print $2}') in

open) xset dpms force on ;;
esac
#echo "LID switched!">/dev/tty5
#logger "ACPI group/action undefined: $1 / $2"
esac
/etc/systemd/logind.conf:

The following is very puzzling as it is a dmesg output after uninstalling pm-utils and disabling systemd-logind service, and systemd-suspend service. My system still wants to go to sleep when the sleep button is pressed and the log show messages from "PM:*" , whatever that is. I initially thought this was a pm-util message, but this persists even after uninstalling pm-utils. Please shed some light on this.

This is my new handler.sh:
#!/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

#maxspeed=`cat /sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_max_freq`
#setspeed="/sys/devices/system/cpu/cpu0/cpufreq/scaling_setspeed"
#set $*
case "$1" in
button/power)
#echo "PowerButton pressed!">/dev/tty5
case "$2" in
PBTN|PWRF) logger "PowerButton pressed: $2" ; poweroff ;;
*) logger "ACPI action undefined: $2" ;;
esac
# button/suspend)

# case "$2" in

Even with the relevant lines commented out and a system restart, my system still wants to suspend
Its become a mystery now. According to me I don't have anything other thatn systemd and acpid which cause automatic standby, but somehow there's some 3rd party involved.
With regards to the lid switch, I will try to put what acpi_listen gives as the acpi call.
And I already tried toggling the LidSwitchIgnoreInhibited option. Not working.
PS: I just temporarily disabled and stopped the logind service to check what is causing this mysterious suspend.
Edit:
This is my acpid log(tail part):
Feb 3 21:02:40 localhost acpid: client connected from 492[0:0]
Feb 3 21:02:40 localhost acpid: 1 client rule loaded
Feb 3 21:02:55 localhost acpid: client 492[0:0] has disconnected
Feb 3 21:02:55 localhost acpid: client 492[0:0] has disconnected
Feb 3 21:02:59 localhost acpid: client connected from 492[0:0]
Feb 3 21:02:59 localhost acpid: 1 client rule loaded
Feb 3 21:03:01 localhost acpid: client connected from 492[0:0]
Feb 3 21:03:01 localhost acpid: 1 client rule loaded
Feb 3 21:03:18 localhost acpid: client 492[0:0] has disconnected
Feb 3 21:03:18 localhost acpid: client 492[0:0] has disconnected
Feb 3 21:03:19 localhost acpid: client connected from 492[0:0]
Feb 3 21:03:19 localhost acpid: 1 client rule loaded
Feb 3 21:03:20 localhost acpid: client connected from 492[0:0]
Feb 3 21:03:20 localhost acpid: 1 client rule loaded
I dunno if this behaviour is correct. It seems like it is just connecting and disconnecting. No events like lid close, suspend are being logged.
