This page provides information for the Gen 6 and Gen 7 version of the Intel-equipped Yoga 7 laptops.

## Installation

If you see `Possibly missing firmware for module xhci_pci` when you run mkinitcpio, you can safely ignore the message as this laptop does not have a Renesas USB3 controller. See Mkinitcpio#Possibly missing firmware for module XXXX for details.

## Accessibility

The speakers do not work out of the box (see below), so in particular speech-aided installation is not possible.

## Power management

### Control Power Saving Modes

Install power-profiles-daemon and then enable/start `power-profiles-daemon.service`.

Desktop environments will then detect support for it.

### Activating S3 sleep

In order to support "Windows Modern Standby", the BIOS does not advertise S3 sleep (suspend to RAM), as discussed in detail in this forum post.

1. The key is visible to `xev` and similar tools
2. The physical key has a symbol on it, which describes its function
3. systemd-logind handles this by default

### Brightness keys

The brightness hotkeys only emit signals after resuming from suspend-to-RAM or hibernation, but not after (re)booting. This is because they depend on initialization by an ACPI method which is called when resuming from a sleep state but not on boot.

This should be fixed in kernel 6.2.x: https://bugzilla.kernel.org/show_bug.cgi?id=214899

## Speaker audio

Install all the packages listed by ALSA firmware.

## Tablet PC

Install iio-sensor-proxy to get the accelerometer working and enable support for screen rotation in Destop Environments such as GNOME or KDE.

Check out Tablet PC for more information.

### GNOME Screen Rotation

See Tablet PC#With GNOME 2.

## Fingerprint reader

There is experimental support for the Goodix 55b4 fingerprint reader this laptop ships with. Thanks to the Goodix Fingerprint Discord.

Note: If you are dual-booting, Windows will reflash the reader every time you boot Windows and then it will not work in Linux until you flash it again (but this does not clear enrolled fingerprints). So it's best to pick one OS to use the fingerprint reader in. You can disable the reader in Device Manager in Windows to prevent reflashing.

To get it working:

1. Install fprintd and libfprint-goodixtls-55x4AUR
2. Follow the instructions at https://github.com/goodix-fp-linux-dev/goodix-fp-dump#how-to-use-it to reflash the firmware of the fingerprint reader
3. Start the fprintd service for the first time and enroll fingerprints in your DE or following instructions in fprint

There is a known issue with this experimental driver where sometimes after a long sleep mode period you will need to restart the fprintd service to get it working again.

## Screen flickering

If you see screen flickering or stuttering, follow the instructions at Intel graphics#Screen flickering.
