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.
