[ubuntu] Fingerprint login help ?? I'm new to ubuntu

HI!

i have a LENOVO t61 that i've just installed ubuntu 14.04.4 LTS on...
all my drivers seem to be working great, top marks ubuntu!

But my fingerprint scaers not working for logins, can anyone point me in the right direction or give me a bit of advice ?

i like feeling like james bond when i log on my pc lol

also yes yes i know this is a old computer but its dual core, 2.5gb ram, and i paid £30 for it and plan on using it just for browsing.
