# Lenovo ThinkPad X1

## Model description

Lenovo ThinkPad X1, Sandy Bridge (Core i5, 2,5 GHz), NWG2MRT This model has SSD 80/HDD 320 pair. Comes without optical drive. Has UEFI BIOS with BIOS-legacy fallback mode. Has Windows 7 Pro pre-installed, with tons of bloatware (bing toolbar, big Lenovo superbar button et all) pre-installed, too.

## Drive space customization

By default:

    - SSD: two WinRE partitions and one Windows system partition
    - HDD: blank

I've chosen to:

    - leave WinRE untouched (there are two such partitions)
    - use SSD for my root partition
    - use HDD for swap, /home, /var (~30 Gb, pacman cache goes here), /tmp

## Installation method

Note: If you'd like to create Windows recovery flash drive, do it before Arch installation with the help of autorun located at recovery partition, from your installed Windows system.

Due to the fact that there is no optical drive, you need to install Arch from USB stick.

### Legacy-BIOS

This procedure is far less involved then UEFI and works perfectly.

In order to turn off UEFI booting you will need to boot into your BIOS and change the boot mode to Legacy. Afterward, follow the Beginners' guide for standard installation instructions.

### UEFI

Installation from UEFI bootable USB works with the default bootloader, so rEFInd is unnecessary. In the BIOS under Startup, set "UEFI/Legacy Boot" to UEFI only. The default partition table (and Windows installation) uses MBR. For UEFI, reformat the disk as GPT.

Booting using an efibootmgr entry works well. The warnings about incompatibility and embedding arguments to do not apply.

## Hardware

Almost everything works out of the box. Install synaptics and video-intel drivers.

### Fingerprint Reader

fingerprint-gui from the AUR is already patched to work with the X1's newer fingerprint reader. To get the gui's dropdown to recognize your device, you'll have to add your user to the `plugdev` group:

    # gpasswd -a <username> plugdev

It has been seen that the relevant udev rules do not get set properly. To do this, open `/usr/lib/udev/rules.d/40-libbsapi.rules` with your favorite text editor to add (or create with) the following lines:

    /usr/lib/udev/rules.d/40-libbsapi.rules

    ATTRS{idVendor}==”147e”, ATTRS{idProduct}==”2020″,   SYMLINK+=”input/touchchip-%k”, MODE=”0664″, GROUP=”plugdev”
    ATTRS{idVendor}==”147e”, ATTRS{idProduct}==”2020″,   ATTR{power/control}==”*”, ATTR{power/control}=”auto”

Restart your computer for the group and udev changes to take effect.

### Adjusting Backlight Brightness

Add `acpi_osi="!Windows 2012"` to your kernel parameters (see https://bbs.archlinux.org/viewtopic.php?id=158775).

## Power management

Just consult Laptop page to read about tp_smapi, pm-utils, uswsusp and acpid.

Tp_smapi does not seem to work at all.

Suspend works fine, even with status indicator.

## Extra Keys

The sleep, wifi, brightness, and keyboard backlight keys all work out of the box. All of the others (volume, media, etc.) can be bound using the standard X labels:

    XF86ScreenSaver
    XF86WebCam
    XF86Display
    XF86AudioPrev
    XF86AudioPlay
    XF86AudioNext
    XF86AudioMute
    XF86AudioLowerVolume
    XF86AudioRaiseVolume
    XF86AudioMicMute
    XF86Launch1 # the black button above F6

## USB3 Issues

With some external devices the USB3 hubs fails to hotplug and can be unstable and only reboots make external drives appear. The only solution I found is a firmware update of the NEC Corporation uPD720200 USB 3.0 Host Controller (rev 04) without official files from Lenovo!

The Firmware and it's installer can be found on station-drivers.com: [1]

Note:

- The Website is mostly in FRENCH! Télécharger means Download!!
- The Installation can only be done from a 64bit Windows! so no 32bit BartPE Windows XP livecd will work and 64 Windows (tested with 64bit Win 7 Pro) has to be installed on the Laptop once to install the Firmware!
- Since this is not officially propagated from Lenovo proceed with caution!
