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 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 i7z.
Video
Intel
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.
/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. It enables the use of Nvidia graphic card via virtualgl. Just follow the instructions for setting up 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]
Audio
Follow the official documentation: ALSA or/and PulseAudio
Pulseaudio
External subwoofer configuration:
We need to create pulseaudio profile which will use external subwoofer. For example add this to /usr/share/pulseaudio/alsa-mixer/profile-sets/extra-hdmi.conf
:
/usr/share/pulseaudio/alsa-mixer/profile-sets/extra-hdmi.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 ...
We need lfe remixing to be enabled in pulseaudio configuration:
/etc/pulse/daemon.conf
enable-lfe-remixing = yes
Set PCM channel in alsamixer to 100% and to prevent volume changing set volume to ignore in /usr/share/pulseaudio/alsa-mixer/paths/analog-output.conf
:
/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
Only if you want to use low pass audio filter for subwoofer, add this to default.pa and install blop,cmt and ladspa:
/etc/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
Alsa
External subwoofer + low pass filter configuration:
This configuration uses blop,cmt and ladspa
/etc/asound.conf

Backlight
Follow Backlight wiki page and use acpi_backlight=vendor acpi_osi=Linux
as kernel parameter in your bootloader.
Touchpad
Follow the Synaptics guide.
Webcam
Working.
Bluetooth
Should be working out of the box - just remember to install bluez-firmware.
Power management
The USB unbind hook is no longer necessary as of Linux 3.5.
