Installation

Consult the standard documentation ( official and unofficial) on Arch Linux installation for general installation steps. What follows are items of particular interest to U120 owners.

Dual Boot Windows/Linux

The U120 ships with three partitions (sizes are approximate):

  • 4GB hidden partition containing system recovery information
  • 35GB Windows XP Home system partition
  • 90GB empty partition for general storage

If you wish to retain Windows XP, choose the manual partition method during the Arch installation and change only the third partition (sda3). You can also use a partition management program to resize the Windows XP partition before installing Arch Linux. This author used a GParted Live CD to reduce the XP partition to 25GB prior to installing Arch.

Kernel Modules (Drivers)

For the most part the hardware should Just Work™. Hardware-specific modules include:

i915            intel graphics
r8169           realtek ethernet
rtl8187se       realtek wifi 
snd_hda_intel   intel audio
uvcvideo        bisoncam nb pro webcam
  • i915 - you will, of course, need to install the xf86-video-intel package and configure Xorg for a proper desktop.
  • uvcvideo - you may need to add this module to the MODULES array in /etc/rc.conf for automatic loading.

AHCI SATA Mode

The U120 supports the AHCI SATA specification, however this feature is disabled in the BIOS by default. To enable AHCI during setup:

  • Add "ahci" to the MODULES array in /etc/mkinitcpio.conf
  • Once Arch installation is complete, reboot and enter the BIOS
  • Change AHCI Mode to "Enabled"

Note: To enable AHCI after installation:

  • Add "ahci" to the MODULES array in /etc/mkinitcpio.conf
  • Run the following as root:
# mkinitcpio -p linux
  • Reboot and enter the BIOS
  • Change AHCI Mode to "Enabled"

Check dmesg output for confirmation. You should see something like this:

ahci 0000:00:1f.2: version 3.0
ahci 0000:00:1f.2: PCI INT B -> GSI 19 (level, low) -> IRQ 19
ahci 0000:00:1f.2: irq 26 for MSI/MSI-X
ahci 0000:00:1f.2: AHCI 0001.0100 32 slots 4 ports 1.5 Gbps 0x5 impl SATA mode
ahci 0000:00:1f.2: flags: 64bit ncq pm led clo pio slum part 
ahci 0000:00:1f.2: setting latency timer to 64
scsi0 : ahci
scsi1 : ahci
scsi2 : ahci
scsi3 : ahci

Advanced Configuration

Touchpad

For touchpad functionality, install the Synaptics touchpad drivers as per the Beginners Guide and Touchpad Synaptics articles.

Hotkeys

Most hotkeys are properly detected by the kernel out-of-the-box and XF86 aliases (XF86AudioMute, etc.) are automatically assigned to most hotkeys as well . The following hotkeys do not produce keycodes, however they do function as intended:

  • Fn+F6 (webcam)
  • Fn+F10 (eco mode)

For more information on the U120 hotkeys, refer to the Tips & Tricks: More on Hotkeys section below.

Webcam Usage

To load the webcam driver automatically you may need to add uvcvideo to the MODULES array in /etc/rc.conf.

Install the cheese application:

# pacman -S cheese

To view input from the webcam, you can use MPlayer:

$ mplayer -tv driver=v4l2:width=640:height=480:device=/dev/video0:fps=15 tv://

Note: You may need to enable the webcam (Template:Keypress) before the above applications will work.

Hard Drive Clicking/Ticking

SATA power management settings are aggressively conservative by default. This can produce a clicking or ticking sound every few seconds as the hard drive head attempts to 'park' itself. Not only is this annoying, it can shorten the life of your hard drive. To avoid this:

Install the hdparm utility.

Add the following to /etc/rc.local:

# lowest SATA power management setting, highest I/O performance
hdparm -B 254 /dev/sda

- or -

# disable SATA power management entirely
hdparm -B 255 /dev/sda

Confirm the current power management setting at any time by running:

# hdparm -B /dev/sda

Tips & Tricks

More on Hotkeys

To make life easier for others, what follows is a list of hotkey definitions for use by xbindkeys:

Fn+F2 (screen)

   m:0x10 + c:214
   Mod2 + XF86Display

Fn+F3 (touchpad) <-- This hotkey will toggle the touchpad regardless of its binding under Linux

   m:0x10 + c:249

   Mod2 + XF86AudioRaiseVolume

Fn+F9 (vol mute)

   m:0x10 + c:160
   Mod2 + XF86AudioMute

Fn+F11 (wifi) <-- This hotkey will toggle the wifi antenna regardless of its binding under Linux

   m:0x10 + c:243
   Mod2 + NoSymbol

Fn+F12 (suspend)

   m:0x10 + c:223
