I am using ubuntu 16.04 on HP ProBook 440 G3. It has a finger print reader. lsusb shows this following driver

Bus 001 Device 004: ID 138a:003f Validity Sensors, Inc. VFS495 Fingerprint Reader


But Fingerprint GUI or Fprint shows no driver , as expected because 138a:003f is not in their supported list.
So how can I use the fingerprint reader with ubuntu?

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

You can install the driver from here. It's an rpm package so you'd need to use alien and you should also need to install other packages. Refer to this for a guide.
