## Configuration
There is a BIOS update (v207) on Asus support website (go to the english one if you don't find) that fix the numpad bug.
### CPU
Works out of the box.
Follow the [CPU frequency scaling](/index.php/CPU_frequency_scaling "CPU frequency scaling") guide to enable speed-stepping. Processor has Intel Turbo Boost which works out of the box, but you can't see the frequencies above 2.4GHz in `/proc/cpuinfo`. To see the actual frequency [install](/index.php/Install "Install") [i7z](https://www.archlinux.org/packages/?name=i7z).
### Video
#### Intel
Follow these guides: [Xorg](/index.php/Xorg "Xorg") and [Intel](/index.php/Intel "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.
`/etc/modprobe.d/blacklist-nouveau.conf` `blacklist nouveau`
#### Nvidia
The official proprietary nvidia drivers for linux do not support Nvidia Optimus yet, but there is a workaround in the form of [bumblebee](https://www.archlinux.org/packages/?name=bumblebee). It enables the use of Nvidia graphic card via virtualgl. Just follow the instructions for setting up [bumblebee](/index.php/Bumblebee "Bumblebee") in our wiki.
#### Outputs
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](https://github.com/Bumblebee-Project/Bumblebee/wiki/FAQ).
### Audio
Follow the official documentation: [ALSA](/index.php/ALSA "ALSA") or/and [PulseAudio](/index.php/PulseAudio "PulseAudio")
##### Subwoofer
###### Pulseaudio
We need pulseaudio profile which will use surround21 alsa device.
`/usr/share/pulseaudio/alsa-mixer/profile-sets/default.conf`
```
...
[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.
`~/.config/pulse/daemon.conf`
```
enable-lfe-remixing = yes
```
To prevent volume changing of PCM set volume to ignore in:
`/usr/share/pulseaudio/alsa-mixer/paths/analog-output.conf.common`
```
[Element PCM]
switch = on
volume = ignore
override-map.1 = all
override-map.2 = all-left,all-right
```
Install [blop](https://www.archlinux.org/packages/?name=blop),[cmt](https://www.archlinux.org/packages/?name=cmt) and [ladspa](https://www.archlinux.org/packages/?name=ladspa) and append these lines to your default.pa 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` ).
`~/.config/pulse/default.pa`
```
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=remapLFE master=ladspa_low_pass remix=no channels=1 master_channel_map=lfe channel_map=lfe
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.
###### Alsa
External subwoofer + low pass filter configuration. Configuration uses [blop](https://www.archlinux.org/packages/?name=blop),[cmt](https://www.archlinux.org/packages/?name=cmt) and [ladspa](https://www.archlinux.org/packages/?name=ladspa).

### Backlight
Follow [Backlight](/index.php/Backlight "Backlight") wiki page and use `acpi_backlight=vendor acpi_osi=Linux` as kernel parameter in your [bootloader](/index.php/Bootloader "Bootloader").
### Touchpad
Follow the [Synaptics](/index.php/Synaptics "Synaptics") guide.
### Webcam
Working.
### Bluetooth
Should be working out of the box - just remember to install [bluez-firmware](https://www.archlinux.org/packages/?name=bluez-firmware).
### Power management
The USB unbind hook is no longer necessary as of [Linux 3.5](http://git.kernel.org/?p=linux/kernel/git/torvalds/linux.git;a=commitdiff;h=dbf0e4c7257f8d684ec1a3c919853464293de66e).
