This article provides information about installing and setting up Arch Linux on the Samsung N140. It is also relevant for the Samsung N130 which is identical except for the omission of Bluetooth and stereo speakers (and possibly a different battery capacity). There are versions of the N130 which include a 3G cellular modem, available from Vodafone and China Mobile. The Samsung NC10 is similar but not identical to the N140, so you may or may not find useful information on that page.

Do the standard Arch installation procedure from the ARCH CD ISO using an external USB CDROM drive. Alternatively boot the Arch installer from a USB flash drive. The standard Arch kernel is recommended.
Configure your installation
RTL8101e/8102e fast ethernet. Works out of the box.
The supplied wifi device is either an Atheros AR9285 (PCI ID = 168c:002b) (European markets) or a Realtek RTL8192E (US and UK markets).
02:00.0 Network controller : Atheros Communications Inc. AR9285 Wireless Network Adapter (PCI-Express) [168c:002b] (rev 01)
The kernel module for this device is "ath9k". Kernels 2.6.32 release candidates and later seem to work fine.
02:00.0 Network controller: Realtek Semiconductor Co., Ltd. RTL8192E/RTL8192SE Wireless LAN Controller (rev 01)
Confirmed working out of the box on the current release (2014.07.03), with 3.15.3 Kernel.
Cellular 3G Modem
The video controller is an Intel chipset that works with the xf86-video-intel driver.

Kernel Mode Setting
See also Intel#KMS .28Kernel Mode Setting.29.
KMS works providing real consoles at the native LCD resolution, 1024x600. There is a known problem with 2.6.32 kernels (later release candidates up to at least release 18.104.22.168), which results in screen flickering and blackouts about 5 minutes after resuming from suspend-to-RAM or suspend-to-disk.
If you are using a kernel with no inital ramdisk and you can simply add the required options to the GRUB kernel line:
# (3) Arch Linux N130 title Arch Linux Custom N130 Kernel root (hd0,YOURROOT-1) kernel /boot/vmlinuz26-N130 root=/dev/sdaYOURROOT resume=/dev/sdaYOURSWAP ro quiet i915.powersave=0 i915.modeset=1
If you are using an initial ramdisk (either the standard kernel or the custom kernel method B above) then do the following:
options i915 powersave=0 options i915 modeset=1
MODULES="intel_agp i915" FILES="/etc/modprobe.d/modprobe.conf"
Put keymap early in
Regenerate the init ramdisk for the kernel(s) you are running:
$ mkinitcpio -p linux
Remove any vga= or video= from grub
/boot/grub/menu.lst kernel line, and reboot.
Brightness function keys confirmed working out of the box on current release (2014.07.03) with 3.15.3 kernel.
External VGA works out of the box with xrandr / krandrtray. Tested at 1920x1080 resolution.
The audio device is an Intel HD.
00:1b.0 Audio device : Intel Corporation 82801G (ICH7 Family) High Definition Audio Controller [8086:27d8] (rev 02)
Suspend and hibernate
Suspend and hibernate work out of the box with
systemd-logind. See below for setting up resuming from hibernation.
/etc/systemd/logind.conf to change default key handling.
/etc/systemd/logind.conf --------------------------------------- HandlePowerKey=poweroff HandleSuspendKey=suspend HandleHibernateKey=hibernate HandleLidSwitch=suspend
Don't forget to restart the service after making changes
# systemctl restart systemd-logind.service
You can call the functions from the command line with
Alternatively using a power manager, for example
xfce4-power-manager, you can control key handling from a GUI.
If you are a KDE4 user you can take advantage of powerdevil (included in kdemod-core/kdemod-kdebase-workspace since release 4.2) to manipulate the screen brightness, cpu scaling and hibernate. Suspend from KDE works too, but if you are using handler.sh to suspend on the button/lid and button/sleep acpi events, then KDE only needs to lock the screen. Note that cpu scaling requires acpi-cpufreq module to be loaded at boot.
Hibernate works out of the box with
systemd, but you need to have a SWAP file/partition.
You will need to add
resume=swap_partition to your kernel parameters. Example below for GRUB.
/etc/default/grub --------------------------------------------- GRUB_CMDLINE_LINUX_DEFAULT="resume=/dev/sda1"
grub-mkconfig -o /boot/grub/grub.cfg
If you use an initramfs (default for Arch), you need to add the
resume hook into the configuration of mkinitcpio
/etc/mkinitcpio.conf --------------------------------------------------------------- # resume must be placed after block and lvm2, but before filesystems HOOKS="... block lvm2 resume filesystems ..."
Then, rebuild the initrd image
# mkinitcpio -p linux
Binding Fn keys in Openbox
In Openbox one can use the internal keybind setup instead of xbindkeys. Example of rc.xml (In this instance, volume Fn Keys):
<keybind key="XF86AudioRaiseVolume"> <action name="Execute"> <command>amixer set Master 5%+ unmute</command> </action> </keybind> <keybind key="XF86AudioLowerVolume"> <action name="Execute"> <command>amixer set Master 5%- unmute</command> </action> </keybind> <keybind key="XF86AudioMute"> <action name="Execute"> <command>amixer set Master toggle</command> </action> </keybind>
