According to Gilles (http://linux.derkeiler.com/Mailing- Lists/Ubuntu/2012-05/msg00053.html)
There are 2 issues at hand, here... 1) The .fprint directory, which stores the fingerprint database of a user, is stored in the encrypted home directory. So is not available to the greeter application to recognize prints. This is what causes the "Could not locate any suitable fingerprints matched with available hardware" message on the login prompt. 2) If you decide to copy these files to /home/YourUser from a command line, without the encrypted home there, then you can actually login from the greeter session, with recognized prints. But then a second phenomenon appears. Since you didn't type your password, there is nothing to unlock your home directory encryption key... which means it doesn't get decrypted... which means you get kicked out of your session immediately as no configuration files are available. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/998367 Title: fingerprint login in ubuntu 12.04 can't access encrypted home user account To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/libfprint/+bug/998367/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
