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.

Should you have enabled the VMD controller in the BIOS, you must add vmd to the mkinitcpio.conf MODULES array before you regenerate the initramfs. See also [1].

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

The important System Sleep State S3 for suspending the device is not available. 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.

For now if you suspend this laptop it will enter S2idle mode by default. This mode will not decrease power consumption by much. It is therefore recommended to use hibernation as the action when the lid is closed.

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 on IdeaPad laptops and Others.

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.

  2. The physical key has a symbol on it, which describes its function.
  3. systemd-logind handles this by default.
