acpi_asus: Asus Laptop Extras

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): acpi_asus_load="YES"
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.
