Yoga 370 は Lenovo 製のコンバーチブルノートパソコンです。2017 年にリリースされました。

インストール

This laptop supports both UEFI and BIOS booting mechanisms. To boot in legacy mode, CSM Support must also be enabled in the UEFI BIOS settings.

ハードウェア

Most of the hardware works out-of-the-box, the exeception are bluetooth, fingerprint reader, accelerometer and ambient light sensor.

Bluetooth

To make bluetooth work you need to install package blueman and bluez

指紋リーダー

Install python-validity^AUR.

Start/enable python3-validity.service after installing package.

ノート: Alternatively you can install package python-validity-git^AUR from AUR

加速度計と環境光センサー

To make this devices work with GNOME you need to install iio-sensor-proxy package.

As of now the version of the iio-sensor-proxy package in the community repository is 3.1 which is outdated and contains a bug that makes it incompatible with the yoga 370 (accelerator does not work). To solve this issue install version 3.3 available on git: tag 3.3.

If you have an outdated version containing the bug you can run monitor-sensor to verify. If it gives the following output:

+++ iio-sensor-proxy appeared
=== Has accelerometer (orientation: undefined)

update to 3.3.

ファームウェア

This laptop supports SecureBoot with custom signed keys. fwupd seems to also work well and without any problems.

ヒントとコツ

指紋リーダーがまったく機能しない

Fingerprint reader may not work, if that happens try to find help on the python-validity github page.

指紋リーダーが機能しなくなる

Sometimes fingerprint reader will stop working after sleep or hibernation for no apparent reason. Enable both open-fprintd-suspend.service and open-fprintd-resume.service if that happens.

Alternatively create a systemd service, by creating the unit /etc/systemd/system/fingerprint-restart.service with the following contents:

/etc/systemd/system/fingerprint-restart.service

[Unit]
Description=It resets fingerprint reader sevice in order for it to work. 
After=suspend.target

[Service]
User=root
Type=oneshot
ExecStart=systemctl restart python3-validity
TimeoutSec=0
StandardOutput=syslog

[Install]
WantedBy=suspend.target

Do not forget to enable fingerprint-restart.service.

スタイラスの充電状態を確認する

To check stylus stylus charge, you need to use:

$ upower -i /org/freedesktop/UPower/devices/tablet_wacom_battery_0 |grep percentage

ノート: GNOME seems to show it out-of-the-box in settings.

タブレットモードでの使用

Detecting whether machine is in tablet mode or laptop mode can be done with

# cat /dev/input/by-path/platform-thinkpad_acpi-event

When you fold/unfold the device appropriate info should be displayed.

If you desire to use this laptop in tablet mode you may be interested in this article about Touchscreen in Arch Linux.
