Asus laptops. It is alike to acpi_asus(4), but uses WMI interface instead of separate ACPI device. On Asus EeePC T101MT netbook it allows to handle hotkeys and on/off WLAN, Bluetooth, LCD backlight, camera, cardreader and touchpad. On Asus UX31A ultrabook it allows to handle hotkeys, on/off WLAN, Bluetooth, Wireless LED, control keyboard backlight brightness, monitor temperature and fan speed. LCD brightness control doesn't work now for unknown reason, possibly requiring some video card initialization. Sponsored by: iXsystems, Inc.

|
|
.Sh SYNOPSIS
|
|
To compile this driver into the kernel,
|
|
place the following line in your
|
|
kernel configuration file:
|
|
.Bd -ragged -offset indent
|
|
.Cd "device acpi_asus"
|
|
.Ed
|
|
.Pp
|
|
Alternatively, to load the driver as a
|
|
module at boot time, place the following line in
|
|
.Xr loader.conf 5 :
|
|
.Bd -literal -offset indent
|
|
acpi_asus_load="YES"
|
|
.Ed
|
|
.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
driver provides support for the extra ACPI-controlled gadgets, such as hotkeys
|
|
and leds, found on recent Asus (and Medion) laptops.
|
|
It allows one to use the
|
|
.Xr sysctl 8
|
|
interface to manipulate the brightness of the LCD panel and the display output
|
|
state.
|
|
Hotkey events are passed to
|
|
.Xr devd 8
|
|
for easy handling in userspace with the default configuration in
|
|
.Pa /etc/devd/asus.conf .
|
|
.Pp
|

Currently, the following Asus laptops are fully supported:
