No nie wiem czy jest tak, jak mówisz. Po kolejnych próbach z jednym, ale innym palcem było tak, że pojawiły się na liście do weryfikacji wprawdzie 2 palce, ale kazał zweryfikować ten, który przypisywałem i nie zaakceptował.

Kod:

george@Mint-Vivobook-ASUSLaptop-M1502IA-D1502IA:~$ fprintd-enroll -f right-middle-finger
Using device /net/reactivated/Fprint/Device/0
Enrolling right-middle-finger finger.

A tak odnośnie polecenia na przypisanie wszystkich palców, to można jeszcze jednym wierszem:

Kod:

for finger in {left,right}-{thumb,{index,middle,ring,little}-finger}; do sudo fprintd-enroll -f "$finger"; done

Mam pytanie, bo znalazłem tez czyjś inny sposób: co sądzisz i czy jest bezpieczny? i Jak się w ogóle wraca/cofa/usuówa zmiany, jeśli coś nie odpowiada? Jak przywrócić system do stanu sprzed danej zmiany?

You can see that my system detects my attached fingerprint reader as an STMicroelectronics Fingerprint Reader. From here all I need to do is install some programs and modify a configuration file.

• Install the applications needed.
  sudo apt install -y fprintd libpam-fprintd
  
• Once install finishes, open /etc/pam.d/common-auth for editing (
  
  
  Kod:

  sudo nano /etc/pam.d/common-auth
  ). Find the line (line 17 on my system) that reads
  auth  [success=1 default=ignore]  pam_unix.so nullok_secure
  and modify the file adding the line shown below in bold. Make sure the order of these lines is the same as shown here.
  auth    [success=2 default=ignore]  pam_fprintd.so max_tries=1 timeout=10
  auth    [success=1 default=ignore]  pam_unix.so nullok_secure
  Save the file (Ctrl+Shift+X, Y, Enter).
  
• Finally, enroll your fingerprint with the following command
  fprintd-enroll $USER
  After running the command, swipe your finger across the reader 3 times to enroll your fingerprint.
  

That's all there is to it. You should now be able to use your fingerprint reader to log in or to authenticate (for things like installations) post-login.
