This page contains instructions, tips, pointers, and links for installing and configuring Arch Linux on the Asus Eee PC 1201N and 1201PN.

The Asus Eee PC 1201NL should be similar, but has a 32-bit Intel Atom N270 CPU and thus requires Arch Linux 32.

## Installing Wireless

- The 1201N has a Realtek 8191 Wireless card, despite what lspci reports that the computer has a Realtek 8171 (rev 10). The wireless driver is included in the Linux kernel and should work out of the box.
- The 1201PN uses Atheros 9k drivers. This may not be the case with all 1201PNs, but at the very least, run `lspci -v` and look for your Network controller. If it is AR9285 Wireless Network Adapter, you can follow the instructions at ASUS Eee PC#Installation. If evdev (it should) is not detecting your card, you will need to add `ath9k` to your `MODULES` array in rc.conf.
- The 1201NL has native support from 3.0 kernel version with rtl8192se module.

## ACPI Functions

In order to use the function keys and extend battery life, you can set up the ACPI Driver, then install and configure the tools below.

The driver for the ACPI functions of the 1201N is called eeepc_laptop. It is part of the mainline kernel, so all that needs to be done is to load the module:

    modprobe eeepc_laptop

If the command fails with such error message:

    FATAL: Error inserting eeepc_laptop (/lib/modules/2.6.32-ARCH/kernel/drivers/platform/x86/eeepc-laptop.ko): No such device

you need to add acpi_osi=Linux to kernel parameters in your bootloader configuration.

### Function Keys

You must have acpid installed and running to use the Function keys.

Then, you need to install acpi-eeepc-genericAUR package from AUR and edit file /etc/conf.d/acpi-eeepc-generic.conf:

    EEEPC_MODEL="1201N"

Comment out EEEPC_CONF_DONE option:

    #EEEPC_CONF_DONE="no"

If you are using linux drivers for wifi you should also edit the WIFI_DRIVERS array:

    WIFI_DRIVERS=("r8192se_pci")

Otherwise the wifi toggle button won't work.

Afterward, you must restart acipd.

## Power management

See Power management and Suspend and hibernate.

## Troubleshooting

### Machine does not resume after suspend2ram

You have to unload r8192se_pci module right before suspending. See Suspend2RAM section of this article for details.

### After suspending the machine immediately resumes

You have to unload usb module(s) before suspending. See Suspend2RAM section of this article for details.

## cpufrequtils (1201N)

The Intel Atom 330 does not support cpufrequtils in any reasonable way, so it is not recommended that you use cpufrequtils. You can disable it in /etc/laptop-mode/conf.d/cpufreq.conf:

    CONTROL_CPU_FREQUENCY=0

Because the Atom uses so little power anyway, controlling the FSB using the "SuperHybrid Engine" should provide significant gain in battery life without the need for CPU scaling.

## HDD important issue (1201NL)

See Laptop#Hard drive spin down problem.

## Function Keys/Power Saving (1201PN)

BE CAREFUL with laptop power-mode settings. The default settings will spin your harddrive down every 20 seconds which is really bad. Read this thread.

You can follow the instructions as outlined in the directions for the 1201NL to get your function keys working.

The acpi-generic-package scripts in the AUR are not necessary to get your function keys working. They are hardware agnostic, so they are nice to get things up and running quickly, but with the exception of the sleep/suspend scripts (which are useful) everything else can be done more quickly with a direct keybinding.

Disable the other settings and use your WMs default keybinding manager (or Xbindkeys) to handle your Wlan/Display/Volume settings.

Xbindkeys Simply bind your keys to the necessary action.
