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 (can be found under System > Preferences) 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.

Removing accents (and diacritics) in any language from Java

import java.text.Normalizer;
import java.text.Normalizer.Form;

// ...

public static String removeAccents(String text) {
    return text == null ? null
        : Normalizer.normalize(text, Form.NFD)
            .replaceAll("\\p{InCombiningDiacriticalMarks}+", "");
}

or 

 public static String deAccent(String str) {
     String nfdNormalizedString = Normalizer.normalize(str, Normalizer.Form.NFD); 
     Pattern pattern = Pattern.compile("\\p{InCombiningDiacriticalMarks}+");
     return pattern.matcher(nfdNormalizedString).replaceAll(""); 
        }
