View Full Version : Logging into Ubuntu without any keyboard activities (a few users)

March 22nd, 2014, 12:36 PM
I belive it will be really easy to most of you here to help me (fprintd topic).

I followed this:


sudo add-apt-repository ppa:fingerprint/fprint
sudo apt-get update
sudo apt-get upgrade
sudo apt-get install libfprint0 fprint-demo libpam-fprintd gksu-polkit

Then I decided to add several users to the Lubuntu system:

sudo adduser mariusz1
sudo adduser mariusz2
sudo adduser mariusz3

Then I needed to scan and to add into system fimgerprints for all users:

fprintd-enroll mariusz
fprintd-enroll mariusz1
fprintd-enroll mariusz2
fprintd-enroll mariusz3

From this time, when default login manager is displayed you can use the fingerprint reader instead of entering a password via keyboard. Although the password field is left blank, and the screen does not appear any relevant information about the success (or not) of the scan. System is still waiting. You must to hit enter key or use the Sign In button to log in to the system.

My ask is (current investigations):

- How to disable the automatic start of Xsession (graphical desktop environment) after computer is powered on (I would like to see a text console only inviteing me to log in) I would like to decide if I need to start graphical environment or not later.

- When I see text console inviteing me to log on I would like to do it without any keboard activities from my side. I want to use fingerprint only. I need Lubuntu know who I am (based on my fingerprint) and log me in. I need this sollution for few users (not only for me). Every of us have his own system account.

- When some of us is logged into system then his own script /home/user/scripts/accepted.sh is run (script added into autostart)

- When someone intruder was trying to log in then some other dennied.sh should be executed

- A would like also automatically save a fingerprints of intruders locally /database/potential_burglars

I would like to improve this sollution for my home automation system:

Could you please help me?

Thank you very much for your help.

Best regards

Fingerprint GUI, available here (http://www.ullrich-online.cc/fingerprint/about.php), works fine for me for logging in, authenticating sudo, etc., but so far I haven't found a way to use fingerprint authentication for logging in to web sites and apps.
