==Not Tested==
Before running the Arch installer, you MUST install and configure a GPT partition scheme. If you do not, you will get '''terrible''' performance when writing small files (which should effect most users).

*HDMI
 
+
==Configuring GPT (Erasing the whole disk)==
+
You must install some tools that are not included in the installer (you do not have to update pacman):
+
<pre>$ dhcpcd eth0</pre>
+
Update `pacman` and install `gdisk`
+
<pre>$ pacman -Syy </pre>
+
<pre>$ pacman -S gdisk</pre>
+
Launch `gdisk`
+
<pre>$ gdisk /dev/sda</pre>
+
 
+
Since you want to start a new GPT table, choose the option to create a new GPT table.
+
The partitioning scheme here is important(!). Since you have to use GRUB2 to boot from a GPT disk, you MUST create a 200MB blank partition that you will never touch again(!). This small partition will hold GRUB2's core.img used for booting.
+
 
+
Using `gdisk`, press `n` to create a new partition, keeping an eye that the start sector should be '''2048''' and for end sector, enter `+200M`. Do not change the partition type; it should default to 8300. '''Remember to not format this in the installer'''.
+
 
+
From here, you can create the rest of your partitions. We will use `parted` to make your drive bootable later. Don't forget to write the changes to disk using the `w` command in `gdisk`.
+
 
+
Here you should '''reboot'''. After you boot back into the installer ISO, reinstall `gdisk`.
+
 
+
Now we need to create an MBR for the GPT disk . This allows GRUB2 to be installed to disk.
+
 
+
Open `gdisk` and press `r`, then press `h`... A common looking process is below:

Input / Touchpad

The keyboard and touchpad work more or less without problems using the xf86-input-keyboard and xf86-input-synaptics modules, respectively. Right- and left-clicking works, as well as Two-Finger scroll. Tapping is enabled out of the box and can be disabled in
 /etc/X/xorg.conf.d/10-synaptics.

Bluetooth

Installing a tool like "blueman" from the AUR and starting the bluetooth DAEMON allowed communication to bluetooth keyboards and mice. Bluetooth speakers not tested. (*users feel free to add to this)

Nvidia GPU (Optimus)

Note: Your best bet for this part is to install 'yaourt' from the AUR to ease in installing the following packages

Read the Bumblebee/optimus page. I will only outline a few things...

You need to install the packages (and all of their dependencies) :

  • bumblebee
  • nvidia-bumblebee
  • nvidia-utils-bumblebee
  • bbswitch

In short, Bumblebee allows you to use the switchable GPU and use it only when you want to via the 'optirun' application.

Be sure to add 'bumblebeed' to your DAEMONS array in rc.conf.

Once you reboot, you should start seeing huge power saving.

To check and make sure that you aren't using your GPU all the time:

$ lsmod | grep nv

Should return nothing, this means your GPU is off.

You can check your GPU by running glxgears with and without the 'optirun' prefix and comparing the Frames Per Second.

Suspend / Hibernate

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

Note: ACPI by default doesn't call pm-suspend, if we want to customize the sleep process, we need pm-suspend

If you want sleep your machine when you close your lid, you need to edit ACPI handler script:

$ nano /etc/acpi/handler.sh

Change line 20, to this:

 SLPB|SBTN)    pm-suspend ;;

And Towards the bottom, make lines 58 and 59 look line like this:

close)
        pm-suspend

So now you can use the hotkey (F1) or close your lid and your laptop will sleep.

Fn Multimedia Keys

As with most Asus laptops/netbooks, this laptop sends its Multimedia events via ACPI. Using `acpi_listen`, I was able to discover the button commands the buttons sent to acpi. Add the following to your /etc/acpi/handler.sh file (make sure you add this after the ;; in the button/lid section):

    button/volumeup)
      amixer set Master 5+
      ;;
    button/volumedown)
      amixer set Master 5-
      ;;
    button/mute)
      amixer set Master toggle
      ;;

You can mess with these values to move your volume at different intervals, 5 seemed to work well for me.

Optimize Power Consumption

Add this to the kernel line of your bootloader[1]:

pcie_aspm=force i915.i915_enable_rc6=1
