我正在尝试让我的指纹传感器 thinkpad x390 Yoga 工作。我printfd
使用 yay 安装了软件包。当我尝试运行时fprintd-enroll
,出现以下错误:

当我尝试第二次运行它时,我得到以下信息:

failed to claim device: GDBus.Error:net.reactivated.Fprint.Error.Internal: Open failed with error: Device 06cb:00bd is already open
我尝试安装thinkfinger

这是我的lsusb

解决办法是更新指纹机固件。我通过以下方式实现:
- 安装 fwupd
sudo pacman -S fwupd
- 检查系统是否可以看到设备:
fwupdmgr get-devices
- 刷新固件数据库:
fwupdmgr refresh --force
- 更新我的固件:
fwupdmgr update
您必须立即重新启动才能应用更新并防止您的设备出现奇怪的行为。
所有这些步骤之后fprintd-enroll
运行就没有问题了
