This is the new Linux driver for Asus laptops. It may also support some
MEDION, JVC or VICTOR laptops. It makes all the extra buttons generate
standard ACPI events and input events. It also adds
support for video output switching, LCD backlight control, Bluetooth and
Wlan control, and most importantly, allows you to blink those fancy LEDs.
This is a driver for Asus laptops, Lenovo SL and the Pegatron
Lucid tablet. It may also support some MEDION, JVC or VICTOR
laptops. It makes all the extra buttons generate standard
ACPI events and input events, and on the Lucid the built-in
accelerometer appears as an input device. It also adds
support for video output switching, LCD backlight control,
Bluetooth and Wlan control, and most importantly, allows you
to blink those fancy LEDs.
For more information and a userspace daemon for handling the extra
buttons see <http://acpi4asus.sf.net>.
For more information see <http://acpi4asus.sf.net>.
If you have an ACPI-compatible ASUS laptop, say Y or M here.
