This page is for the Lenovo Yoga 14s 2021 (ITL / IHU) laptop with Intel Core i5-1135G7 / i5-11300H processor, delivered starting from 2020-11-01 (China). It may be branded with different model names in other regions.

Most things will work out-of-the-box, if you just follow the normal set-up method. However, there are some issues you may want to solve before or during installation.

## Installation

You may want to do some configuration during installation, to avoid some annoying issues. You may also want to add them when configuring your boot loader. (See #Keyboard for details.)

Add the following kernel parameters when booting the installation media (Live CD):

    i8042.dumbkbd

If your WiFi interface is missing, simply power-off and re-boot your device.

## Keyboard

The keyboard may not function correctly, esp. normal input will not work. The behaviours include: 1. keyboard light not switchable; 2. only some functional hotkeys are functioning. The issue may disappear after some time (varying from a few seconds to tens of minutes), or maybe not.

An easy way to workaround this is to add a kernel parameter during booting:

    i8042.dumbkbd

Note: The Caps Lock LED will not work with this method, though Caps Lock is functioning as expected.

Alternatively, you may want to use this kernel patch for a proper fix that makes the Caps Lock LED work normally.

## Screen

Users may experience far more laggy animations in Plasma Wayland sessions than in X11 ones. This situation is known to be greatly relieved if this extra kernel parameter is added:

    i915.enable_guc=3

This workaround is only tested on an i5-11300H processor. One should test if it works on i5-1135G7 too.

## Wireless

The WiFi interface is missing sometimes after rebooting from Windows, but `rfkill` can still discover it.

It is known that after powering-off and booting again, this will be corrected.

## Audio

This laptop requires firmware in order for the sound card to work. See Advanced Linux Sound Architecture#ALSA firmware.

## Webcam (Infrared)

This laptop comes with infrared camera and light, to support Windows Hello. The infrared webcam can be detected on Linux automatically, but the light does not work by default.

To make them work, install and configure linux-enable-ir-emitterAUR.

See more instruction on Howdy, a program that imitates Windows Hello on Linux.
