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.conf(5):
DESCRIPTION¶
The
acpi_asus
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 with the
default configuration in
/etc/devd/asus.conf.
Currently, the following Asus laptops are fully supported:
- xxN
- A1x
- A2x
- A3N
- A4D
- A6VM
- D1x
- J1x
- L2B
- L2D
- L2E
- L3C
- L3D
- L3H
- L4E
- L4R
- L5x
- L8x
- M1A
- M2E
- M6N
- M6R
- S1x
- S2x
- V6V
- W5A
- Eee PC
Additionally,
acpi_asus
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
- CRT
4
- TV-Out
Some models also support video switching via the generic
acpi_video(4) driver. Most models do not,
however.
Defaults for these variables can be set in
sysctl.conf(5), which is parsed at boot-time.
