lsusb lists the fingerprint reader in the x240 as follows:

Bus 002 Device 003: ID 138a:0017 Validity Sensors, Inc.

There exists experimental driver support for this in a fork of libfprint for vfs5011 sensors, however you'll need to compile the driver yourself. To get the fingerprint sensor to work for lightdm login, su etc, follow these steps.

1. Install fingerprint-gui:

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

1. Get your IP Address

echo `ifconfig $(netstat -nr | grep -e default -e "^0\.0\.0\.0" | head -1 | awk '{print $NF}') | grep -e "inet " | sed -e 's/.*inet //' -e 's/ .*//' -e 's/.*\://'`

2. Modify your hosts file

var arr = [
  { foo: 'bar', lorem: 'ipsum' },
  { foo: 'bar', lorem: 'ipsum' },
  { foo: 'bar', lorem: 'ipsum dolor sit amet' }
];

arr = arr.map(JSON.stringify).reverse() // convert to JSON string the array content, then reverse it (to check from end to begining)
  .filter(function(item, index, arr){ return arr.indexOf(item, index + 1) === -1; }) // check if there is any occurence of the item in whole array

How to create an HTTPS certificate for localhost domains

This focuses on generating the certificates for loading local virtual hosts hosted on your computer, for development only.

Do not use self-signed certificates in production ! For online certificates, use Let's Encrypt instead (tutorial).
