I have a Dell laptop with fingerprint reader built in. I just ran lsusb with the following result:
Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 001 Device 006: ID 138a:00a6 Validity Sensors, Inc.
Bus 001 Device 005: ID 0cf3:e009 Atheros Communications, Inc.
Bus 001 Device 004: ID 0bda:0129 Realtek Semiconductor Corp. RTS5129 Card Reader Controller
Bus 001 Device 003: ID 0bda:5689 Realtek Semiconductor Corp.
Bus 001 Device 002: ID 04ca:00ac Lite-On Technology Corp.
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Is it possible to use fingerprint scanning instead of traditional login with 18.04 and Unity ?
