[gpm] Mess with hardware brightness keys

[Maxim Levitsky <maximlevitsky gmail com>]

I am owner of an notebook which has hardware brightness keys, and this
is what happens when I press brightness up/down key:


1 - hardware changes the brightness

2 - in kernel acpi driver changes the brightness - can be disabled 
(brightness_switch_enabled=0)

3 - acpi driver sends a brightness/up down event using its own event
device - gpm sees this and again changes the brightness

4 - keyboard also generates brightness up/down events - gpm again
changes brightness.


What do you suggest to do here?
