In order to install, secure boot must be disabled in the BIOS. You can enter it by pressing F2 (or Fn+F2) during bootup. In order to access the boot-menu allowing you to choose a non standard boot device (like USB devices), press F12 (or Fn+F12) during bootup.

Initially, both keyboard and touchpad are unusable, see individual Keyboard and Touchpad sections below.


The keyboard does not work in neither Xorg nor Wayland, only in the TTY. In order to get it working, add i8042.dumbkbd to the kernel parameters. Note that the Caps Lock LED stops turning on after this.


The touchpad is barely usable, only with the "right" pressure. https://gitlab.freedesktop.org/libinput/libinput/-/issues/604.

Luckily, the fix is easy. As mentioned in the bug report, just create file /etc/libinput/local-overrides.quirks with the following content:

[Lenovo Yoga Slim 9 Pressurepad]

After that, log out and log in again and the touchpad should work.


While Lenovo is known to support fwupd in general, the Yoga Slim 9 has not been added yet.

Firmware data path

The BIOS comes with a "self healing" backup BIOS, stored in EFI/Lenovo/BIOS/SelfHealing.fd. The file is about 16M in size and is written each time you make changes to the BIOS (manual modification or BIOS update).


Bluetooth mostly works out of the box. Sometimes it is necessary to restart the service (particularly after suspending). Restart bluetooth.service to fix it.


The laptop comes with an Realtek ALC287 audio chipset, that is unfortunately known to have bad support in Linux, see https://bugzilla.kernel.org/show_bug.cgi?id=208555. To fix the speaker you can force snd_hda_intel instead of snd_sof to handle your audio. A configuration for modprobe.d can be found here: https://github.com/PJungkamp/yoga9-linux/blob/main/config/etc/modprobe.d/snd.conf


The laptop comes with an Intel Corporation Wi-Fi 6 AX201 (802.11 ax) wireless controller, working out of the box.

Battery Conservation Mode

Lenovo offers a "Battery Conservation Mode". When the conservation mode is enabled, your battery will only be charged to 60% to maximize its lifespan. You can use ideapad-cmAUR to control the conservation mode.
