A: No it's actually a kernel thread that is running due to an acpi module that is loaded into the kernel, like "thermal" or "battery". You can use the kernel argument noacpi in grub to disable acpi in the kernel. --[[User:VitaminJ|VitaminJ]] 05:33, 18 February 2011 (EST)

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
       ;;
