According to Gilles (http://
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.
