This page provides information for the Gen 6 and Gen 7 version of the Intel-equipped Yoga 7 laptops.
Many of these points mentioned here should also be applicable to Gen 8 versions. See
Lenovo Yoga 7i Gen 8 (16IRL8)
for details on one specific Yoga 7i Gen 8 model.
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
.

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
Sound Open Firmware
.
If your speakers sound tinny due to ALSA only using the tweeters, use the
snd-sof-intel-hda-common hda_model=alc287-yoga9-bass-spk-pin
kernel module parameter
.
On more recent kernels (>=6.11.0 at least), use
snd-sof-intel-hda-generic hda_model=alc287-yoga9-bass-spk-pin
instead.
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:
Install
fprintd
and
libfprint-goodixtls-55x4
AUR
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
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
.
