Activate and use laptop Fingerprint Reader in ubuntu

This post will guide you step by step, how to Activate and use laptop Fingerprint Reader in Ubuntu.

for Further Information Please follow this link

Step 1

Add this PPA to your sources:

  sudo add-apt-repository ppa:fingerprint/fprint
  sudo apt-get update
  sudo apt-get upgrade

Step 2

Install the Software:

 sudo apt-get install libfprint0 fprint-demo libpam-fprintd gksu-polkit

Important Note:

If you have experimented with fingerprint authentication before and have changed your /etc/pam.d/common-auth, you may be presented with a screen asking whether you want to override those changes. Select Yes. Under very special circumstances, you may get an error saying

   pam-auth-update: Local modifications to /etc/pam.d/common-*, not updating.
   pam-auth-update: Run pam-auth-update --force to override.

In this case, run “sudo pam-auth-update --force”, exactly as suggested, and enable the fprintd profile manually. Leave the standard system profiles (Unix, Keyring and ConsoleKit) enabled as well.

Step 3

Launch “fprint project demo” and check that you can enroll and verify your fingerprints and that your reader is indeed supported.

Step 4

Run “fprintd-enroll” in terminal to save your fingerprint.

system will request you to enroll the finger  print.

That's All :)

Now lock your screen and unlock by fingerprint reader :)
