Fingerprint Reader on Lenovo Thinkpad x220

Hey guys, I'm having a few problems installing the fingerprint reader on Arch Linux. I have the 147e:2016 UPEK fingerprint reader according to lsusb. As far as I know, libfprint-UNSTABLE supports that, but I think it causes a few problems too. Sometimes fingerprint-gui crashes from "Segmentation Fault" and I tried adding it to the PAM sudo file, but whenever I run sudo something, it doesn't ask for a finger swipe. The green light also does not turn on. So, I tried manually running /lib/security/pam_fingerprint-gui.so and it returned "Segmentation Fault." I followed the fingerprint-gui on the Fprint page on the Arch wiki, but didn't work. So then I tried the fprint method, but all the packages they listed to install (Excluding PAM) were not found. I googled the package names (libfprint and pam_fprint) and it returned results from the arch package place, but when I clicked on them, it said the packages weren't found. Any ideas on where I could go from here?

I've had better results with Thinkfinger which is in the extra repo.

Yes, I have used thinkfinger on my other thinkpad, by sadly thinkfinger does NOT support my reader.

Just a FYI. I did some poking around on this and found something interesting, so I thought I'd pass it along.

Disclaimer: I have NOT tried this, and don't even own the fingerprint reader in question.

Anyway, here's the trail I followed...

The ThinkWiki page here:

   http://www.thinkwiki.org/wiki/Integrate … int_reader

points to patches from a year ago in this bug report:

   https://bugzilla.redhat.com/show_bug.cgi?id=504399

So I downloaded the libfprint-0.4.0-1.fc15 and fprintd-0.4.1-1.fc15 Fedora 15 source RPM packages by drilling down from here:

   https://admin.fedoraproject.org/updates … b1ec4e90dc

Then I exploded the RPMs and looked at the "spec" files... and here's where it got interesting.

Fedora seems to be getting the source code for both libfprint and fprintd from here:

   http://people.freedesktop.org/~hadess/

and not from the "official" code repository like the Arch AUR packages do.

So... you may want to give that code a try... or not
