- ACPI hotkey driver for Panasonic laptops
SYNOPSIS
To compile this driver into the kernel,

kernel configuration file:

DESCRIPTION
The
driver enables such hotkey facilities of various Panasonic laptops as
changing LCD brightness, controlling mixer volumes, entering sleep or
suspended state and so on.
On the following models it is reported to work: Let's note (or
Toughbook, outside Japan) CF-R1N, CF-R2A and CF-R3.
It may also work on other models as well.
The driver consists of three functionalities.
The first is to detect hotkey events and take corresponding actions,
which include changing LCD luminance and speaker mute state.
The second role is to notify occurrences of the event by way of
devctl(4)
and eventually to
devd(8).
The third and last is to provide a way to adjust LCD brightness and
sound mute state via
sysctl(8).

There are 9 hotkeys available on the supported hardwares:
Fn+F1
