Slimlock configuration

on a macbook air 4,2 i could not get the suggested configuration for slimlock on lid close to work:

DISPLAY=:0.0 su -c - username /usr/bin/slimlock

i had to use:

su -s $USERNAME /bin/sh -c "/usr/bin/slimlock"

(suggested complimentary configuration)

Screen Brightness

I had no luck with a screen brightness step of 1, in acpi handler. Adding these clauses to handler.sh works better.

   video/brightnessdown)
       bl_dev=/sys/class/backlight/acpi_video0
       actual_bl=`cat $bl_dev/actual_brightness`
       # Lower brightness has no effect until it is lowered enough to change actual_brightness.
       # Brightness less than 10 causes problems when increasing!
       while [ $actual_bl -gt 10 -a $actual_bl == `cat $bl_dev/actual_brightness` ]
       do
           echo $((`cat $bl_dev/brightness` - 1)) > $bl_dev/brightness
       done
       ;;
   video/brightnessup)
       bl_dev=/sys/class/backlight/acpi_video0
       actual_bl=`cat $bl_dev/actual_brightness`
       # Change in brightness has no effect until it is changed enough to change actual_brightness.
       while [ $actual_bl -lt 100 -a $actual_bl == `cat $bl_dev/actual_brightness` ]
       do
           echo $((`cat $bl_dev/brightness` + 1)) > $bl_dev/brightness
       done
       ;;
