|
|
.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
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
|
|
.Xr sysctl 8
|
|
interface to manipulate the brightness of the LCD panel and the display output
|
|
state.
|
|
Hotkey events are passed to
|
|
.Xr devd 8
|
|
for easy handling in userspace.
|
|
.Pp

|
Currently, the following Asus laptops are fully supported:
