<p>Greetings Benjamin,</p>
<p>Thanks for your answer.</p>
<p>I just tried fprint on a Lenovo X1 Carbon ThinkPad (with
integrated fingerprint reader as well) running Kali Linux
(latest release available).</p>
<p>I have the same problem with the login screen but I get other
messages with journalctl (please see attached screenshot).</p>
<p>Does it ring any bell on your side ?</p>
<p>Also, are you the lead developer of fprint package as I
understand it now ?</p>
<p>Thanks a lot for your precious time and help.</p>
<p>Have a nice and safe week-end.<br>

<div>Hi,</div>
<div><br>
</div>
<div>honestly, the PAM stuff is kind of painful, and I don't
remember how to debug it. There is nothing interesting in the
log, as far as I can tell.</div>
<div><br>
</div>
<div>I would still expect a PAM misconfiguration of some sort.
It should go into pam_fprintd.so at some point, but e.g. I
don't even have that enabled locally right now. But, this is
Fedora, and there it is configured using authselect.</div>

<p>Greetings Benjamin,</p>
<div> </div>
<p>Thanks so much for the quick answer.</p>
<div> </div>
<p>Here are my answers to your questions (<font
color="#26a269"><b>==> Like this</b></font>):</p>
<div> </div>
<div>So, fprintd-verify and fprintd-enroll work, but pam not?</div>
<div> </div>
<div><font color="#26a269"><b>==> Yes Sir.</b></font></div>
<div> </div>
<div><br>
</div>
<div> </div>
<div>Seems like something is broken in the PAM stack. It is
hard to tell what though, as the only error form fprintd is
that Release is called without first claiming the device,
for which I have no explanation. Maybe auth log has more
information?</div>
<div> </div>
<div><font color="#26a269"><b>==> There is no
/var/log/auth.log on SuSE Linux so I checked
/var/log/messages and found that when I lock the desktop

<p>Greetings,</p>
<div> </div>
<div> </div>
<div> </div>
<p>I have SuSE Linux Enterprise Desktop (SLED) 15 SP5 and
I use KDE Plasma X11 with fprintd package installed (<span
style=" font-family:'Verdana','Geneva','Arial','Helvetica','sans-serif'; font-size:small;">v
1.94.2-bp155.2.3.1</span>) to unlock the desktop using
the integrated fingerprint reader of an HP ZBook 17 G8
Fury (lsusb says: "Bus 003 Device 003: ID 06cb:00f0
Synaptics, Inc." which is supported by fprint). <br>
</p>
<div> </div>

<div> </div>
<p>It worked fine for some weeks but after some SLED 15
SP5 updates (using zypper up), something broke fprintd
package and SuSE Technical Support does not find what
:-(</p>
<div> </div>
<div> </div>
<div> </div>
<p>I can't unlock anymore the desktop with my fingerprint.
I get "Unlocking failed" error message and I have to
enter the password with the keyboard as before. <br>

</div>
<div>So, fprintd-verify and fprintd-enroll work, but pam
not?</div>
<div><br>
</div>
<div>Seems like something is broken in the PAM stack. It is
hard to tell what though, as the only error form fprintd
is that Release is called without first claiming the
device, for which I have no explanation. Maybe auth log
has more information?</div>
<div><br>
</div>
<div>Also, does it even prompt you for a fingerprint on the
console?</div>
