I want to use a finger print reader device to log in from the Greeter(lock screen).

I tried fprint, which made it possible to use it instead of sudo password, but is it possible to unlock the elementary lockscreen with it? (I suppose fprint works in Ubuntu, but I guess that elementary uses something different for a lockscreen).

This is a known bug: https://bugs.launchpad.net/pantheon-greeter/+bug/1437540

It seems that it will be fixed in Loki, as you cn see the state of the bug: A patch has being requested to merge...

  • That's great news! Can't wait to use it in Loki! :) Commented Feb 29, 2016 at 8:27

Greeter doesnt like it when you first boot. If you lock your screent though it will unlock. just not first boot.

I would like a resolution to this as well. Would be nice to see fprint built-in and fingerprint registration on the user setup plugin.
