NAME
acpi_asus
- Asus Laptop Extras
SYNOPSIS
To compile this driver into the kernel,
place the following line in your
kernel configuration file:
device acpi_asus
Alternatively, to load the driver as a
module at boot time, place the following line in
loader.conf5:
acpi_asus_load="YES"
DESCRIPTION
The
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
sysctl(8)
interface to manipulate the brightness of the LCD panel and the display output
state.
Hotkey events are passed to
devd(8)
for easy handling in userspace.
Currently, the following Asus laptops are fully supported:
xxN
A1x
A2x
A3N
A4D
A6VM
D1x
J1x
L2B
L2D
L2E

L3H
L4E
L4R
L5x
L8x
M1A
M2E

M6R
S1x
S2x
V6V

Additionally,
also supports the Asus-compatible
ATK0100
interface found in
Samsung P30/P35
laptops.
SYSCTL VARIABLES
The following sysctls are currently implemented:
hw.acpi.asus.lcd_brightness
Makes the LCD backlight brighter or dimmer (higher values are brighter).
hw.acpi.asus.lcd_backlight
Turns the LCD backlight on or off.
hw.acpi.asus.video_output
Sets the active display to use according to a bitwise OR of the following:
0
No display
1
LCD
2

4
TV-Out
Some models also support video switching via the generic
acpi_video4
driver.
Most models do not, however.
Defaults for these variables can be set in
sysctl.conf5,
which is parsed at boot-time.
