NAME
acpi_asus_wmi - Asus Laptop WMI Extras
SYNOPSIS
To compile this driver into the kernel, place the following line in your
kernel configuration file:
device acpi_asus_wmi
Alternatively, to load the driver as a module at boot time, place the
following line in loader.conf(5):
acpi_asus_wmi_load="YES"
DESCRIPTION
The acpi_asus_wmi driver provides support for the extra WMI-controlled
gadgets, such as hotkeys and leds, found on Asus laptops. It allows one
to use the sysctl(8) interface to manipulate the brightness of the LCD
panel and keyboard backlight, power on/off different internal components,
such as WiFi, Bluetooth, camera, cardreader, etc, read some sensors.
Hotkey events are passed to devd(8) for easy handling in userspace with
the default configuration in /etc/devd/asus.conf. Some hotkey events,
such as keyboard backlight and touchpad control, are handled inside the
driver.
SYSCTL VARIABLES
The following sysctls are currently implemented:
dev.acpi_asus_wmi.0.handle_keys
Specifies whether driver should handle some harwdare keys, such
as keyboard backlight, internally.
Number of other variables under the same sysctl branch are model-
specific.
Defaults for these variables can be set in sysctl.conf(5), which is
parsed at boot-time.
