# 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 Secure Boot and dual UEFI/BIOS boot enabled by default. Unless you are comfortable in attempting to set up UEFI boot, it's simpler to get an after-market operating system installed if the booting is switched to BIOS-only. In the BIOS/EFI menu, set booting to "Legacy Only" (which uses BIOS emulation instead of EFI).

If using UEFI for your installation, you may want to consider the following:

- Secure Boot must be disabled in order to boot a non-Windows operating system. Go to Security > Secure Boot and set Secure Boot to Disabled. You may also want to put it into Setup/Custom Mode.
- If the security chip is enabled, this can sometimes prevent your bootloader's bootx64.efi from being booted. Under Security > Security Chip, set Security Chip Selection to Discrete TPM and Security Chip to Disabled.

### 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

## Tweaks

### Screen resolution and scaling

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 default resolution is set to 96dpi.

If you have a 1920x1080 FHD panel installed and find that text and UI elements are too small, it may interest you to consider using display scaling to adjust the size of UI elements to your preference. Integer HiDPI scaling is likely too excessive for a display of this resolution and size, so you will want to consider a fractional scaling solution.

### Backlight

See Backlight.

### Touchpad

Most responsive configuration is obtained through xinput.

Decent Synaptics configuration, utilizing sane settings for the X1-Carbon:

## Updating the BIOS

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