The greeter doesn't pick up fprintd's fingerprint readings

[Zisu Andrei]

Recently saw a driver was developed for the fingerprint sensor my laptop has, so I installed fprint according to https://launchpad.net/~fingerprint/+archive/ubuntu/fprint

I have configured it and it works fine with sudo and (I believe it is called) gksu.

The following line is present in /etc/pam.d/common-auth:

auth [success=2 default=ignore] pam_fprintd.so timeout=10 # debug

In the greeter, there is no feedback about about fingerprint login being present or fingerprint strokes happening (in the case they have failed).

So, it's either:
a) the login screen doesn't know about the configuration so it doesn't act accordingly
b) the fingerprint strokes are registered, but they are unsuccessfull, but there is no feedback presented

Is there anyone who can advise on how I can identify the problem? I can even try and fix it if pointed to the right place (i.e. source-code location).

I have the same problem on my Thinkpad x201. Is there no solution to this problem ? If it has already been addressed elsewhere, I haven't found it.

Yes. I've developed a temporary fix. I need to polish it and will upload it.

Hello @matzipan do you plan to send for merge the fingerprint text prompt style from your repo here: http://bazaar.launchpad.net/~matzipan/egtk/egtk/revision/641 any time soon?

Currently the "Swipe your finger" prompt next to the fingerprint icon is small and plain black and not very visible especially with a picture background in the greeter.

Cheers.

Hey Vishal,

Yes, it's currently waiting on approval from Dan. I'll chase him up.
