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.

In general, Linux kernel 6.14 minimum is required for most peripherals to function properly.

ForcePad

The ForcePad functions needs kernel driver for Intel THC (Touch Host Controller) which is upstreamed to Linux kernel 6.14. The following config is already enabled for linux:

config

CONFIG_INTEL_THC_HID=m
CONFIG_INTEL_QUICKSPI=m
CONFIG_INTEL_QUICKI2C=m

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.

Conversely, non-MIPI cameras are expected to work out of the box.

Kernel Support

Support for IPU7 was merged into the staging area of kernel 6.17, however the driver for the IMX471 sensor has not been upstreamed.

The camera sensor driver can be installed using DKMS: imx471-dkms-git^AUR

IPU bridge support is also needed. For kernel versions 6.17 and 6.18, drivers/media/pci/intel/ipu-bridge.c must be patched to support the sensor. See this GitHub issue for patch details. 6.19+ has support out-of-the-box [1].

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, which as of v0.6.0 supports IPU7.
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 user 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 key is visible via evtest and similar tools
The physical key has a symbol on it, which describes its function
An LED indicates the state of this switch
This event is handled by "ThinkPad Extra Buttons"
This event is handled by "Video Bus"

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.
