acpi/ is being populated so I' reworked an old patch I made and
I post again it ported from NetBSD
all these key events are catched (alas no events for volume keys):
BrightnessDownPressed
BrightnessDownReleased
BrightnessUpPressed
BrightnessUpReleased
DisplaySwitchPressed
DisplaySwitchReleased
ZoomPressed
ZoomReleased
SuspendPressed
SuspendReleased
on my laptop (vaio vgn c1s/h model) brightness keys are mapped to:
Fn+F5 increase brighteness
Fn+F6 decrease brighteness
and it works.
I'm trying to understand the role of the SPIC (SNY6001 hid) so I'm wondering
if there is any nasty side effect in bypassing it and always
applying the Fn key initialization sequence as I've made
suggestions?
