Installation
Use F2
to enter BIOS. You must disable Secure Boot to be able to boot from the installation media. UEFI boot mode (OS Optimized Defaults) is working fine and can be used.
Firmware
Support for firmware updates through fwupd is supported. But Lenovo so far only provides firmware updates for devices where Linux is officially supported (Thinkpad/ThinkCentre series). As this is not a device of these series, do not expect firmware updates through fwupd.
Firmware updates through fwupd are supported (but unavailable) for the following components:
- System firmware (Lenovo)
- UEFI (Lenovo)
- NVM Express Solid State Drive (Sandisk)
Suspend
Suspending to system sleep state S3 is not available on the Intel 11th gen mobile CPUs found in this laptop [1]. Forcibly suspending the device to S3 leads to it locking up. If this happens, you can restore your device to working order via a hard reset. To hard reset the Yoga 9, press the power button for at least 15 seconds.
More recent Linux kernels will instead detect and use system sleep state S0ix automatically, this leads to a battery drain of ~0.4%/hour, or ~5% over 12 hours [2]. If you wish to eliminate battery drain considering using hibernation Power management/Suspend and hibernate#Hibernation.
You can configure your machine to hibernate after sleeping in S0ix for a specific duration of time by configuring the lid close action to suspend-then-hibernate
and tuning HibernateDelaySec
. This configuration creates a balanced profile, allowing the machine to wake quickly after suspending while preventing battery drain over long periods of inactivity.
Accelerometer
You must use iio-sensor-proxy-gitAUR instead of iio-sensor-proxy for the accelerometer to work. It is important to note, that the trigger for tablet mode does currently not work. At least within KDE you can enable automatic screen rotation only globally.
Sound
This laptop requires firmware in order for the soundcard to work. See Advanced Linux Sound Architecture#ALSA firmware.
Thermals
It is recommended to enable OS Optimized Defaults
in the BIOS settings. Enabling this option improves the thermal properties of the system tremendously. Without it, thermald will not throttle the system before it is near its critical temperature. You may want to select the appropriate cooling strategy in the BIOS (intelligent/performance/power saving).
Power management
Tools like tp_smapi or tpacpi-bat do not work with this device.
To set the Battery Conservation Mode see Laptop/Lenovo#Battery conservation mode.
Wireless devices
Rfkill reports two additional devices (ideapad_wlan
, ideapad_bluetooth
). Blocking or unblocking these devices has no effect. Instead use the devices:
-
phy0
for Wireless LAN -
hci0
for Bluetooth
Function keys
Fn lock only locks for F1
to F12
. The Ins
and the PrintScreen
buttons still require the use of Fn
even with Fn lock enabled.
The keys Fn+Ins
and Fn+PrintScreen
only function with ideapad-wmi-fn-keys-dkms-gitAUR.

- The key is visible to
xev
and similar tools. - The physical key has a symbol on it, which describes its function.
- systemd-logind handles this by default.
- Only with ideapad-wmi-fn-keys-dkms-gitAUR
Tablet Mode
Installing yoga-usage-mode-dkms-gitAUR will generate the necessary events to trigger tablet mode.
