This page is for the Lenovo Yoga 14s 2021 (ITL) laptop equipped with Intel Core i5-1135G7 and evo platform, delivered starting from 2020-11-01 (China). It may be branded using different model names in other regions.
Most things will work out-of-the-box, or just follow the normal set-up method. However, there are some issues you may want to solve before or during 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 manager. However, you can skip this if you wish. (See #Special issues for details.)
Add the following kernel parameters when booting the installation media (Live CD):
If your WiFi interface is missing, simply power-off and re-boot your device.
Keyboard not functioning properly
The keyboard may not function correctly, esp. normal input will not work. The behaviour includes: 1. keyboard light not switchable; 2. only some functional hotkeys are functioning. The issue may disappear after some time (varies from a few seconds to tens of minutes), or maybe not.
One way to workaround this is to add a kernel parameter during booting:
This is due to Panel Self Refresh (a power saving feature of Intel iGPUs). See Intel graphics#Screen flickering for more information.
The current recommend way is to disable it, by adding with this extra kernel parameter:
Incomplete screen refresh rates
This laptop comes with a screen that supports both 60Hz and 90Hz refresh rate. However, only 90Hz will be detected on Linux automatically. This may lead to extra power consumption.
To add 60Hz (temporarily and/or permanently) for Xorg, follow the instructions in Xrandr#Adding undetected resolutions. Just change the refresh rate instead of resolution would do the trick.
WiFi interface missing
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 not working
This laptop requires firmware in order for the soundcard to work. See Advanced Linux Sound Architecture#ALSA firmware.
Infrared light not working
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 configureAUR.
See more instruction on Howdy, a program that imitates Windows Hello on Linux.
Touch screen and pen not working
Update kernel to version >= 5.10.15
