Login using fingerprint reader

Fingerprint GUI is working just fine in Ubuntu 12.04 Beta1 (LightDM). You can log in, unlock screen, and authenticate everything in the GUI and also "sudo's" in a terminal. I'm using it on an old ThinkPad R52 with integrated SGS Thomson Microelectronics Fingerprint Reader.

Install instructions: Fingerprint GUI

This is available in the repositories as well a sourcefourge

libpam-thinkfinger

ThinkFinger is a driver for the UPEK/STMicroelectronics fingerprint reader. The device is usually found either as a standalone USB device, built into USB keyboards or built into laptops (usually from Dell, IBM/Lenovo and Toshiba).

pam_thinkfinger is a Pluggable Authentication Module that allows the user authenticates through his fingerprint.

The recommended package thinkfinger-tools can be used to acquire, verify and automatically store user fingerprints.

This has worked flawlessly for me through Ubuntu 12.04/12.10 with an SGS Thomson Microelectronics Fingerprint Reader.

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

Exit your session, login again and run Fingerprint GUI to set it up [0483:2016]

fingerprint-gui doesn't work for me. But fprint project works fine for Ubuntu 14.04 and Vostro 5480. Try it:

sudo add-apt-repository ppa:fingerprint/fprint
sudo apt-get update
sudo apt-get install libfprint0 fprint-demo libpam-fprintd gksu-polkit

There is an issue with 1.05 under Ubuntu 10.04 with upek devices. I am using 147e:2016 Upek Biometric Touchchip/Touchstrip Fingerprint Sensor on some hosts and a Lenovo W520. Creating the symbolic links:

cd /usr/lib
ls -l libbs*
-rw-r--r-- 1 root root 4219952 Oct  9  2011 libbsapi.so
lrwxrwxrwx 1 root root      20 May 14 09:00 libbsapi.so.4.0 -> /usr/lib/libbsapi.so
lrwxrwxrwx 1 root root      15 May 14 09:05 libbsapi.so.4.3 -> libbsapi.so.4.0

as described in

http://darkblue.homeip.net/fingerprint/Forum/topic.php?TopicId=303&Posts=7

fixes the problem. My old fingerprints are recognized, I can register new ones without an endless loop in fingerprint-gui and it accepts all fingers during login or sudo and not only the leftmost one.

With Ubuntu 13.04 after installing libbsapi policykit-1-fingerprint-gui fingerprint-gui, when we try running fingerprint-gui especially those who have 138a:008 (VFS301), the device would not sop after first initiation and hence you cannot proceed.

This has been fixed in the libfprint 1.5.1 version and hence download the source and compile it. Do not use the launchpad version as it has dev_open identification issue.

Also after installing make ln -s for /usr/local/lib/libfprint.s0.0.0.0 to /usr/lib/libfprint.s0.0.0.0. Otherwise it would point to the old version installed using apt-get.

This happened to me and after installing latest version of libfprint, I succeeded.

You can follow this unix.stackexchange link also to check your fingerprint versions

This Worked for me as posted on this bugs.launchpad.net link:

"Ok guys I have built a deb package for 64 bit systems. After you download the package i attached you just need to sudo dpkg -i and it will install the driver. If you want the integrated ubuntu fingerprint features for login and sudo, apt-get install fprintd libpam-fprintd. Then go to users and you will see the fingerprint login button option. Enroll your fingerprint and voila! The only annoyance is that on the login screen when it asks for your fingerprint the process isn't like windows. You swipe your finger and if the fingerprint is recognised it will display a login button you have to click. If the fingerprint isnt recognised it will time out and ask for you user password."
