This tutorial is for validity fingerprint reader VF3000 found in Dell Vostro series laptops but might help you. http://www.tuxtrix.com/2012/05/how-to-activate-validity-fingerprint.html

Steps from above link

Before you install this, please remove the fingerprint-gui ppa
```
sudo ppa-purge  ppa:fingerprint/fingerprint-gui
```
This has only been tested on amd64 system. We are awaiting packages for 32bit systems
The program is still under development, so expect a few crashes and error reports

To install the driver for the fingerprint reader, follow the instructions below:
1. Add this PPA to your sources:
```
sudo add-apt-repository ppa:fingerprint/fprint
sudo apt-get update
sudo apt-get upgrade
```
2. Download the libfprint package and Install the software packages:
```
 sudo apt-get install libfprint0 fprint-demo libpam-fprintd gksu-polkit
 sudo dpkg -i libfprint0_0.4.0+git20120202-0ppa1~precise2_amd64.deb`
```
3. Log out and then log back in
4. Open "Users and Accounts" and then click fingerprint to register your fingerprint. See the screenshots below on how to register your fingerprint.

Instead, use the link below because you might have wrong repos. I tried it and it is working for me.

GUI FINGERPRINT SCANNER

As long as your laptop has a scanner, the above method should work

You can also try this method

Install proprietary Validity driver via terminal as below.

Download the .tar file from here on Google Drive and cd to the directory where it was saved, then run these commands:

tar xf vfs495.tar
cd vfs495
sudo apt-get install alien
sudo alien Validity-Sensor-Setup-4.5-118.00.x86_64.rpm
sudo dpkg -i validity-sensor-setup_4.5-119_amd64.deb
sudo apt-get install libssl1.0.0
sudo ln /usr/lib/x86_64-linux-gnu/libssl.so /usr/lib/libssl.so.0.9.8
sudo apt-get install libcrypto++-dev
sudo ln /usr/lib/libcryptopp.so.9 /usr/lib/libcrypto.so.0.9.8

Compile and install libfprint

mkdir libfprint
cd libfprint
rpm2cpio ../libfprint-0.0.6-18.20.1.src.rpm | cpio -i --make-directories
tar xf libfprint-0.0.6.tar.bz2
cp ../libfprint-validity.patch ./libfprint-validity.patch
cd libfprint-0.0.6/
patch -p1 < ../libfprint-validity.patch
sudo apt-get install libusb-dev libcrypto++-dev libssl-dev libglib2.0-dev libmagickcore-dev checkinstall
./configure --prefix=/usr
make
sudo checkinstall -install=no make install
sudo dpkg -i libfprint_0.0.6-1_amd64.deb

Compile and install fprint_demo

cd ../..
sudo apt-get install libgtk2.0-dev
tar xf fprint_demo-0.4.tar.bz2
cd fprint_demo-0.4
./configure --prefix=/usr
make
sudo checkinstall -install=no make install
sudo dpkg -i fprint-demo_0.4-1_amd64.deb

Finally, enroll a finger

sudo /etc/init.d/vcsFPServiceDaemon start
sudo fprint_demo

This pop-up should appear

Enroll your right index finger.

You should now be good to go
