如何在 Ubuntu 或 Linux Mint 中的新 Lenovo Ideapad-520-15IKB 上安装指纹 GUI？

当我在命令行中输入：lsusb -s 001:003 -v我得到以下信息：

因为它无法打开总线 001 上的设备 003：ID 06cb：0081 Synaptics,Inc.，所以指纹根本不起作用。

通常应该按顺序输入以下命令：

sudo add-apt-repository ppa:fingerprint/fingerprint-gui
sudo apt-get update
sudo apt-get install libbsapi policykit-1-fingerprint-gui fingerprint-gui

解决方案？

答案1

似乎某些设备被 BIOS 设置停用，
请参阅dmesg | grep -i tpm

设置 BIOS 以启用“安全芯片”，并在“安全”部分和“I/O 端口”部分启用指纹传感器设备。

对于我的（旧）联想 Thinkpad，我必须从 3 个不同的部分编辑 BIOS 设置。
