    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
    L3C
    L3D
    L3H
    L4E
    L4R
    L5x
    L8x
    M1A
    M2E
    M6N
    M6R
    S1x
    S2x
    V6V
    W5A

    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
    CRT
    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.
