Hardware

CPU: Intel Core i7-2630QM @ 2.00GHz

Mainboard: Intel HM65 Express

RAM: 6/8GB DDR3

Display: 15,6" HD LED (1920x1080)

Graphics adapter: Intel Core Processor Integrated Graphics Controller, NVIDIA GeForce GT 555M

Soundcard: Integrated Intel HDA, Bang & Olufsen speakers with external subwoofer

Network: Atheros Gigabit Ethernet Controller, Intel Centrino Wireless-N 1030

Hard disk: Seagate Momentus 750GB 5400rpm SATA

Touchpad: Synaptics

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 and/or Pulseaudio

To make the external subwoofer work edit/create /etc/modprobe.d/alsa-base.conf and add these options:

/etc/modprobe.d/alsa-base.conf

options snd-hda-intel model=asus-mode4

As explained in this bug report, by default, the subwoofer plays the right channel. To correct this, add the following:

/usr/share/pulseaudio/alsa-mixer/profile-sets/extra-hdmi.conf

[Mapping analog-surround-21]
device-strings = surround40:%f
channel-map = front-left,front-right,lfe,lfe
paths-output = analog-output analog-output-speaker
priority = 7
direction = output

And enable this:

/etc/pulse/daemon.conf

enable-lfe-remixing = yes

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.
