To get started, burn the image to a USB stick using BalenaEtcher. Install all firmware updates in Windows and the Lenovo utility.
In Lenovo x13s’s BIOS config, disable Secure Boot (this will create problems with Windows Bitlocker, unless you disable that first.)
Insert USB and press F12 during boot to select it. Be patient during first boot during filesystem resize; it might take multiple minutes depending on the disk.
It is recommended to create Lenovo’s Windows USB recovery disk before wiping your Windows install. You might require it to deploy firmware updates. Windows ARM64 on this machine is Lenovo-specific and the generic Win ARM64 images won’t work.
For now, only Ubuntu Lunar (via Concept x13s PPA) has the userspace required for working audio and battery charging support, and a patched mesa for accelerated graphics.
Debian Trixie/Sid and Ubuntu Mantic have a more recent mesa that does not need patching, but no working battery charge nor audio.
Installation:
- Download Khadas Rescue system (flash to SD card, insert, power on, hold FUNCTION and short press RESET button)
- Download Armbian image and place it to the USB drive (copy .xz or .img file, do not flash with Etcher)
- Boot into Khadas OOWOW and install to eMMC by selecting image from USB drive
Enable 3D Acceleration (Ubuntu variant only):
sudo add-apt-repository ppa:liujianfeng1994/panfork-mesa sudo add-apt-repository ppa:liujianfeng1994/rockchip-multimedia sudo apt update sudo apt dist-upgrade sudo apt install mali-g610-firmware rockchip-multimedia-config # In order to install additional packages with hardware acceleration support like chromium sudo apt install chromium-browser
