Note
The 14-inch model and the 15-inch model are two different models designed by two different teams. They do not use the same firmware release package. The following description may not apply to certain models.
ForcePad
For 14" Sensel touchpad, you can adjust haptic feedback using
hid-tools
:
# hid-feature set /dev/hidraw1 -f b0000 <value 1-100>
and click force with:
# hid-feature set /dev/hidraw1 -f d0000 <value 1-3>
The device reverts to default settings after reboot. We can make it permanent through udev rules:
etc/udev/rules.d/99-sensel.rules
SUBSYSTEM=="hidraw", ACTION=="add", ENV{ID_VENDOR_FROM_DATABASE}=="Cirtech (UK) Ltd", RUN+="/usr/bin/hid-feature set /dev/%k -f b0000 50", RUN+="/usr/bin/hid-feature set /dev/%k -f d0000 1"
TouchScreen
Same as
#ForcePad
.
Stylus
Same as
#ForcePad
.
Audio
This laptop requires
Sound Open Firmware
in order to make the sound card working.
Power Management
There are typically battery charging adjustments available for ThinkPad laptops.
See
Power management/Suspend and hibernate#Changing suspend method
.
Ambient Light Sensor
This model needs
linux-firmware-intel
for the ambient light sensors.
Webcam
Certain models feature a MIPI camera (Sony IMX471 sensor) connected to the Intel IPU7 interface. Unlike standard USB webcams, this requires a complex driver stack and is not yet supported out-of-the-box.
Kernel Support
The camera sensor driver is yet to be upstreamed, but for now can be installed using DKMS (
imx471-dkms-git
AUR
) with at least Linux kernel 6.19.
After install, you can verify the module is loaded with
$ lsmod | grep imx471
User Space
The proprietary Intel HAL is currently difficult to setup on Arch. An alternative is using
libcamera
's SoftISP, which processes the raw sensor data on the GPU or CPU.
There is a caveat that picture quality is currently worse than the proprietary stack.
Install
libcamera
Install
pipewire-libcamera
to bridge the camera to
PipeWire
.
You can check if your camera is working with
$ qcam
.
WirePlumber Configuration
WirePlumber
may not monitor libcamera devices by default. Create the following configuration file to force it.
~/.config/wireplumber/wireplumber.conf.d/10-libcamera.conf
wireplumber.profiles = {
  main = {
    monitor.libcamera = required
  }
}
Restart the relevant services:
$ systemctl --user restart wireplumber pipewire
Tip
You can enable pipewire support in
Firefox
by going to about:config and setting
media.webrtc.camera.allow-pipewire
To true
IR Camera
Same as
Webcam
. The driver for the IR camera sensor (HM1092) is not available yet.
Firmware
Can be updated via
fwupd
or the official bootable ISO updater provided by Lenovo.

The physical key has a symbol on it, which describes its function

Fn
and
LeftCtrl
can be swapped in the BIOS menu. The keycaps are the same size, so they could theoretically also be swapped to match the BIOS setting.
As of BIOS version N4DET32W (1.15 on the X9-14), the "Fool proof FN Ctrl" feature is enabled by default and
Fn+C
,
Fn+V
and some other act as
LeftCtrl+C
etc…
Fingerprint sensor
Fingerprint sensor is located on the power button, reported as "Synaptics Sensors".
The fingerprint reader works out of the box using
fprintd
. See
Fprint
.
