Q: Can someone add a section about this? Is it an alternative to ACPID?

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

Screen Brightness

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

       # 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
