I recently bought a Thinkpad (T440p) and installed Ubuntu 13.10. It should be certified for Ubuntu.

But there is one thing, which doesn't work out of the box. My Validity Sensors fingerprint reader (138a:0017) isn't usable. How can I configure it and use this in Ubuntu?

  • It is certified when preinstalled by the manufacturer, and for Ubuntu 12.04 x64 - though the sensor does seem to show here. I believe you may be able to try using libfprint, but there is a bug report here that may be relevant. – Wilf Feb 19 '14 at 13:31
  • libfprint only tells me that it couldn't find my device – damien Feb 19 '14 at 17:18
  • yes I did ... also the bug-report talks about 138a:0018 not 138a:0017 ... ok I'll try compiling it from there – damien Feb 19 '14 at 17:37
  • Dunno then. Sorry. Whoops - you need this comment that links here. – Wilf Feb 19 '14 at 17:41

Finally the official package libfprint0 in repo of 15.10 does support this reader(138a:0017).

I have a T440p with same fingerprint reader, I've tried it some weeks ago as login credential.

Now I give it up, because comparing with windows driver and application, its accuracy is a bit poor; but at least, it can be correctly recognized by system.
