This page contains instructions, tips, pointers, and links for installing and configuring Arch Linux on the ASUS Zenbook UX31E Ultrabook. (There is probably little/no difference with his 11" little brother, the UX21E)

Installation issues

If you get an error trying to format partitions when installing Arch try adding this line to the kernel parameters

libata.dma=0

UEFI Booting

As of 21-Feb-2012 Grub2 seems to disagree with Asus UEFI, halting at "Loading inital ramdisk", use BIOS instead.

Compatibility

Touch Pad

There are different versions of the UX31, some have Sentelic and some have Elenatec - Touch pads.

Elenatec Touch pads

Touch & Scroll works out of the box. Clickpad functionality does not. (However, using two and three finger touches for right an middle click works fine).

If higher pressure must be applied to your touchpad in order to function properly, tweak the following properties according to your needs [1]

synclient FingerLow=5
synclient FingerHigh=15

Alternatively, edit your /etc/X11/xorg.conf.d/10-synaptics.conf

Section "InputClass"
       Identifier "touchpad catchall"
       Driver "synaptics"
       MatchIsTouchpad "on"
       MatchDevicePath "/dev/input/event*"
       Option "TapButton1" "1"
       Option "TapButton2" "3"
       Option "TapButton3" "2"
       Option "VertTwoFingerScroll" "1"
       Option "HorizTwoFingerScroll" "1"
       Option "FingerLow" "5"
       Option "FingerHigh" "15"
EndSection

Tip : Multifinger taps; two finger for middle click, three fingers for right click.

Sentelic Touchpads

The Sentelic Touchpad drivers have been added to the 3.2 kernel, so it should work out of the box by now. However this only supports basic functionality, for scrolling and other features one of the following two patches must be used.

ReubenBond

ReubenBond has made contact with a sentelic representative who has provided him with official documentation on putting the device into absolute positioning mode. The latter can be accessed here: http://fsp-lnxdrv.svn.sourceforge.net/viewvc/fsp-lnxdrv/trunk/doc/fsp_packet.txt?revision=43&view=markup

This looks very promising and ReubenBond is committed to developing a driver in the next few weeks. This is all referenced in the forum https://bbs.archlinux.org/viewtopic.php?id=125262&p=2

Saaros

Saaros's driver works well for two finger and side scrolling and is fairly straight forward to apply and build. Unfortunately however, it does slightly impede normal functionality, pointing doesn't seem quite as accurate, tapping doesn't seem quite as sensitive and tapping and dragging/selecting can be quite tricky. This code should eventually be accepted into the official kernel: https://github.com/saaros/sentelic/issues/2.

Graphics

Works out of the box

HDMI Out

There seems to be an issue whereby having an HDMI device plugged in at boot results in the screens being switched and also the laptop screen not coming on. To make this more bearable you can automate switching HDMI on with the following udev rule and script:

ACTION=="change", SUBSYSTEM=="drm", RUN+="/usr/sbin/hdmi-plugged"
#!/bin/bash

export XAUTHORITY=/home/$USER/.Xauthority
export DISPLAY=:0

/usr/bin/xrandr -display :0 --output eDP1 --auto --output HDMI1 --auto --above eDP1

Wireless

Works fine with the ath9k driver, included in the kernel since 2.6.27. Edit rc.conf as root and add ath9k to the MODULES array.

Warning: Do not forget to install the wireless_tools and wpa_suppliant packages during the installation since you will get stuck with no internet access if you don't!

Unstable Wireless when using Network Manager

Some users experience connection drops when using wireless. For some users this can be fixed by setting the wireless connection's BSSID (usually the router's MAC address). This only works if your wireless connection only has one access point as the BSSID is unique for each access point.

Ethernet - USB adapter

Note: The Asix USB ethernet drivers are included in the current (3.2.2-1) kernel, so it should work out of the box now

The Ethernet USB adapater which comes with the ASUS UX31 and UX21 models is the Asix "USB to Fast Ethernet" adapter, model AX88772B. At the present, the device is not recognized by the currently available kernels. However, the source for the driver for Linux Kernels 2.6.38 and later can be downloaded at the following link: AX88772B Linux Driver v4.2.0: http://www.asix.com.tw/FrootAttach/driver/AX88772B_772A_760_772_178_LINUX_Driver_v4.2.0_Source.zip.

Once downloaded, the source needs to be compiled. First unzip the file as follows:

unzip AX88772B_772A_760_772_178_LINUX_Driver_v4.2.0_Source.zip

Next, go into the unzipped directory and compile the source as follows:

cd AX88772B_772A_760_772_178_LINUX_Driver_v4.1.0_Source
make

Install the just compiled module:

sudo make install

Finally load the module:

sudo modprobe asix

That's it. You should be able to connect using a wired connection now.

Solid State Drive

Check Solid_State_Drives

Power Management

Suspend to RAM

The USB modules must be unloaded or the laptop won't come out of sleep mode.

Put

SUSPEND_MODULES="xhci_hcd ehci_hcd uhci_hcd"

in

/etc/pm/config.d/unload_module

PCIe ASPM

Do not add the following option to the kernel line

pcie_aspm=force 

if

dmesg | grep -i "acpi fadt"

outputs

ACPI FADT declares the system doesn't support PCIe ASPM, so disable it.

i915

Enabling i915_enable_rc6 will improve battery perfomance significatively but might also cause sudden shutdowns if you run an old or unpatched kernel. To enable it, add the following option to your kernel line.

i915.i915_enable_rc6=1

To check the current state of all i915 parameters execute as root (bash)

for i in /sys/module/i915/parameters/*;do echo ${i}=`cat $i`;done

Module parameter details

modinfo i915

You may suffer sudden shutdowns. This is an issue in the kernel (prior 3.2.7 and 3.3.0-rc4). To fix this, you have to patch your kernel (see the bug report on freedesktop: https://bugs.freedesktop.org/show_bug.cgi?id=44867, be sure to read every messages). When the stability of the fix will be confirmed the patch will reach the stable tree so it is likely that kernel >= 3.3 won't need to be fixed.

Additional powersavings

Configure Laptop_Mode_Tools and don't forget to check CPU_Frequency_Scaling
