fingerprint-gui stucks na primeira repetição com errcode -22

Question

minha nova impressão digital instalada-gui stucks quando tento registrar meus dedos. O primeiro escaneamento dá um sinal verde, mas quando o programa me pede para repetir o passo, o escaneador não o escaneia. Normalmente, o scanner pisca em verde durante a leitura, mas não depois do primeiro deslize ... O scanner usado é de um Thinkpad T440,

ID 138a:0017 Validity Sensors, Inc. Fingerprint Reader

a versão do Ubuntu é 15.10 e o sistema está atualizado. Aqui está um log erorr detalhado:

Onde está o problema, ou mais específico, o que significa erro -22? Eu não encontrei nenhuma lista de significados de erro > para impressão digital-gui ...

O resto do progam parece funcionar, a fingerprinter sempre pisca quando auth é necessário e só mostra o erro que não foi capaz de abrir a pasta com os fprints armazenados (porque não existe tal pasta desde que nenhum dedo foi armazenado com sucesso ...)

ingerprint-helper[3182]: Could not open /var/lib/fingerprint-gui/wucke/vfs5011/

Então, obrigado por quaisquer dicas, sugestões ou conselhos ...

Você tentou o Fprint? link

Eu tenho o mesmo problema antes de tentar fingerprint-gui. Agora eu uso o Fprint e funciona
