--- Comment #35 from zzra...@protonmail.com --- Okay I made live persistence image of kubuntu to try this because this is highly unusual to me since I use Arch. Same thing happened to me when logging in after enabling fingerprint authentication but I managed to fix it. This is basically what you need to do: sudo pam-auth-update -> enable fingerprint authentication Then edit `/etc/pam.d/sddm` with your favorite editor: sudo vim /etc/pam.d/sddm I have commented following line: @include common-auth and added 2 new lines so it looks like this: ... auth [success=1 new_authtok_reqd=1 default=ignore] pam_unix.so try_first_pass likeauth nullok auth sufficient pam_fprintd.so #auth sufficient pam_succeed_if.so user ingroup nopasswdlogin #@include common-auth ... At last, reboot. Now I can use fingerprint to login after pressing Enter in password field. Also works for lock screen and sudo commands. Also make sure fingerprint reader is enabled in BIOS. -- You are receiving this mail because: You are watching all bug changes.
