Same problem on a Dell Vostro 5480 with reader 138a:0011 Validity Sensors, Inc. VFS5011
But the problem does not occur on fprint_demo. I posted a message to fingerprint-gui about this: http://home.ullrich- online.cc/fingerprint/Forum/topic.php?TopicId=519&Posts=0 Here's a copy of I what I observed and posted to the fingerprint-gui forum ================================== Hi, I just got a Dell Vostro 5480 with a fresh Ubuntu 14.04 pre- installed by Dell. Tried to use Fingerprint-GUI, but cannot enroll. First enroll works, and all the others fail. My reader is: Bus 002 Device 014: ID 138a:0011 Validity Sensors, Inc. VFS5011 Fingerprint Reader I searched the Internet and found 5 or 6 similar posts on several forums, all with no solution. Here's the details: Install: sudo add-apt-repository ppa:fingerprint/fingerprint-gui apt-get update apt-get upgrade sudo apt-get install libbsapi policykit-1-fingerprint-gui fingerprint-gui Logged off and logged in >From a terminal, I tried: fingerprint-gui or fingerprint-gui debug The reader is detect, and I can select the finger. When I go to the Scan/Verify tab, it says "Please swipe Your Right Index" I swipe the finger and it shows OK with a green check and asks for a second scan, but no more scans work. auth.log shows: Feb 6 14:45:31 vostro fingerprint-gui[20691]: Need 1 stages.

BUT, if I test with fprint-demo (version 0.4): $ sudo apt-get install fprint-demo $ fprint_demo It works perfectly! I can enroll several fingers, identify, scan, etc. There is an open bug at launchpad saying that the problem is on libfprint, but all works on fprint_demo. Maybe libfprint is called differently on fprint_demo and on fingerprint-gui? https://bugs.launchpad.net/ubuntu/+source/libfprint/+bug/1415348 Any ideas? thanks!
