# Lenovo ThinkPad T440s

From ArchWiki

This article covers the installation and configuration of Arch Linux on a Lenovo T440s laptop.

## Installation

### UEFI vs BIOS

The T440s has SecureBoot and UEFI enabled by default. Unless you know you want to use UEFI, it's simpler to get Arch installed if booting is switched to BIOS-only. In the BIOS/EFI menu, set booting to "Legacy only" (which uses BIOS emulation instead of EFI).

### Driver Selection

Device | Driver Package
--- | ---
Video | Intel graphics
ClickPad | libinput
Wireless/Bluetooth | iwlwifi*
Finger Print Reader | Fprint since V 0.6.0
SD-Card Reader (Realtek RTS5227) | rts5227-dkmsAUR

Note*: Depending on what you picked when ordering the laptop, you might have a stock ThinkPad wireless card. Check this page for more information.

### Tp_smapi

See tp_smapi and a configuration for ThinkPad T420.

## Tweaks

### Screen resolution

In order to use the real dpi value create the file (`/etc/X11/xorg.conf.d/90-monitor.conf`):

    Section "Monitor"
        Identifier             "<default monitor>"
        DisplaySize            309 173    # In millimeters
    EndSection

Otherwise the defalut resolution is set to 96dpi.

### Backlight

See Backlight.

### Touchpad

- Good configuration for touchpad

## Updating the BIOS

Warning: Flashing motherboard BIOS is a dangerous activity that can render your motherboard inoperable!
