I couldn’t find any good search engine hits for this, so I’m posting up the details to help others find it.
Supposedly most Lenovo laptops contain a fingerprint reader that works nicely in Ubuntu via ThinkFinger. However my Lenovo T400s uses different hardware (Upek) that isn’t supported by ThinkFinger.
You can find out what hardware your fingerprint reading is by running:
$ lsusb | grep -i finger Bus 004 Device 002: ID 147e:2016 Upek Biometric Touchchip/Touchstrip Fingerprint Sensor
If yours says Upek line mine does, you can get it running under Ubuntu (and Fedora etc..) by installing fingerprint-gui. The installation process is a little tedius, but it’s worth it to be able to login/sudo/etc.. with a swipe of your finger.
Probably worth getting a few friends to test how susceptible the reader is to false positives though.
