Hi,

a Debian user reported a regression in lightdm-gtk-greeter between 1.1.6 and 1.6.0 (only noticed now because of the upgrade to Jessie). He's using fingerprint based authentication using fprint pam module, and that stopped working after 1.1.6.

The downstream bug report is https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=783406 in case you need more information.

I'm a bit puzzled since I don't really think the greeter handles the authentication itself, but it seems that downgrading really fixes the problem so it does look like a regression somewhere.

Is there any chance to emulate fingerprint reader?

For the sake of completeness I will add here what I added on the downstream bugreport

Contrary to the findings of the reporter, lightdm-gtk-greeter 2.0.1-2 (as found in Debian Testing) does authenticate using fingerprint, but needs an extra keypress to actually login.

So fingerprint authentication does work in more recent version, with a quirk
