There is a BIOS update (v207) on Asus support website (go to the english one if you do not find) that fix the numpad bug.


Works out of the box.

Follow the CPU frequency scaling guide to enable speed-stepping. Processor has Intel Turbo Boost which works out of the box, but you cannot see the frequencies above 2.4GHz in /proc/cpuinfo. To see the actual frequency install i7z.



Follow these guides: Xorg and Intel. You will need to blacklist the nouveau driver (the kernel detects the nvidia card and loads it). Bumblebee will load it as needed, see next section.

blacklist nouveau


The official proprietary nvidia drivers for linux do not support Nvidia Optimus yet, but there is a workaround in the form of bumblebee. It enables the use of Nvidia graphic card via virtualgl. Just follow the instructions for setting up bumblebee in our wiki.


VGA out works fine out of the box. Since the NVIDIA chip is wired to the HDMI out, you can get this working using Bumblebee with xf86-video-intel-virtual-crtc and hybrid-screenclone. See Bumblebee FAQ.


Follow the official documentation: ALSA or/and PulseAudio



We need pulseaudio profile which will use surround21 alsa device.

[Mapping analog-surround-21]
device-strings = surround21:%f
channel-map = front-left,front-right,lfe
paths-output = analog-output analog-output-lineout analog-output-speaker analog-output-desktop-speaker
priority = 10
direction = output

Lfe remixing must be enabled for remixing third channel.

enable-lfe-remixing = yes

To prevent volume changing of PCM set volume to ignore in:

[Element PCM]
switch = on
volume = ignore
override-map.1 = all
override-map.2 = all-left,all-right

Install blop,cmt and ladspa and append these lines to your if you want to configure subwoofer on every pulseaudio daemon start:

Note: Before using this configuration you should change alsa_output.pci-0000_00_1b.0.analog-stereo-21 to your own name of sink(you can find names of your sinks in pulseaudio with command $ pactl list sinks ).
load-module module-ladspa-sink  sink_name=ladspa_low_pass master=alsa_output.pci-0000_00_1b.0.analog-stereo-21 plugin=lp4pole_1671 label=lp4pole_fcrcia_oa control=200,0

load-module module-remap-sink   sink_name=remap20         master=alsa_output.pci-0000_00_1b.0.analog-stereo-21 remix=no   channels=2 master_channel_map=front-left,front-right channel_map=front-left,front-right
load-module module-combine-sink sink_name=combine         slaves=remap20,remapLFE                                         channels=3                                           channel_map=front-left,front-right,lfe
set-default-sink combine

Commands to control volume:

pactl set-sink-volume 0 +10%
pactl set-sink-volume 0 -- -10%
pactl set-sink-mute 0 toggle
Note: When we compare pulseaudio and alsa low pass filter configuration we find out that subwoofer is less heard, it is because pulseaudio use own remixing method which sends to subwoofer half of left and right channel.

External subwoofer + low pass filter configuration. Configuration uses blop,cmt and ladspa.

Follow Backlight wiki page and use acpi_backlight=vendor acpi_osi=Linux as kernel parameter in your bootloader.


Follow the Synaptics guide.




Should be working out of the box - just remember to install bluez-firmwareAUR.

Power management

The USB unbind hook is no longer necessary as of Linux 3.5.
