FingerPrint Login for Ubuntu 14.04 (BioMetric)

To login your laptop using Finger Print with Ubuntu 14.04; you need the Finger Print GUI.

To install the same follow the instruction below.

Installation
=======
1. First of all, if you have installed Fingerprint GUI manually before, get rid of it completely. Remove all binaries, shared libraries, any other files and undo all the  changes you have made to your system config files (especially to files under /etc/pam.d/).

2. Add this PPA to your sources:

sudo add-apt-repository ppa:fingerprint/fingerprint-gui
sudo apt-get update

3. Install the packages:

sudo apt-get install libbsapi policykit-1-fingerprint-gui fingerprint-gui

4. Log out of your session and log back in (we need the new session defaults to be picked up).

Setup
=====
After installation launch “Fingerprint GUI” and enrol your fingerprints.
That should be all you need to do!
Try locking your screen, logging out and in, sudo in terminal and running graphical apps requiring root privileges.

Uninstallation
===========
The package policykit-1-fingerprint-gui replaces GNOME’s standard PolicyKit daemon (contained in package policykit-1-gnome). However, when you decide to uninstall Fingerprint GUI (and hence remove policykit-1-fingerprint-gui), policykit-1-gnome will not get automatically installed back, hence there won’t be any PolicyKit daemon in the system, and APT will try to remove all the packages that depend on it. Therefore, if you want to remove Fingerprint GUI, make sure you install policykit-1-gnome back first.
sudo apt-get install policykit-1-gnome
sudo apt-get remove fingerprint-gui
