.Sh SYNOPSIS
|
||
|
|
To compile this driver into the kernel,
|
||
|
|
place the following line in your
|
||
|
|
kernel configuration file:
|
||
|
|
.Bd -ragged -offset indent
|
||
|
|
.Cd "device acpi_asus_wmi"
|
||
|
|
.Ed
|
||
|
|
.Pp
|
||
|
|
Alternatively, to load the driver as a
|
||
|
|
module at boot time, place the following line in
|
||
|
|
.Xr loader.conf 5 :
|
||
|
|
.Bd -literal -offset indent
|
||
|
|
acpi_asus_wmi_load="YES"
|

.Sh DESCRIPTION
|
||
|
|
The
|
||
|
|
.Nm
|
||
|
|
driver provides support for the extra WMI-controlled gadgets, such as hotkeys
|
||
|
|
and leds, found on Asus laptops.
|
||
|
|
It allows one to use the
|
||
|
|
.Xr 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
|
||
|
|
.Xr devd 8
|
||
|
|
for easy handling in userspace with the default configuration in
|
||
|
|
.Pa /etc/devd/asus.conf .
|
||
|
|
Some hotkey events, such as keyboard backlight and touchpad control, are
|
||
|
|
handled inside the driver.
|
||
|
|
.Sh SYSCTL VARIABLES
|
||
|
|
The following sysctls are currently implemented:
|
||
|
|
.Bl -tag -width indent
|
||
|
|
.It Va dev.acpi_asus_wmi.0.handle_keys
|
||
|
|
Specifies whether driver should handle some harwdare keys, such as keyboard
|
||
|
|
backlight, internally.
|
||
|
|
.El
|
||
|
|
.Pp
|
||
|
|
Number of other variables under the same sysctl branch are model-specific.
|
||
|
|
.Pp
|
||
|
|
Defaults for these variables can be set in
|
||
|
|
.Xr sysctl.conf 5 ,
|
||
|
|
which is parsed at boot-time.
