Thanks but no thanks. I followed your instruction up until Reboot and check if the fingerprint options are shown in User settings. Now you should be able to add your fingerprint(s). If this doesn't work for you, consider downgrading fprintd to version 1.90.9-1. Also you could try to add them manually using `fprintd-enroll`. Now assuming you have enrolled your fingerprint(s). You can check if the fingerprint is working for lock screen and login screen. Keep in mind that login in with fingerprint works but it won't unlock the KWallet so I recommend login in with password, but you can unlock screen or use approve sudo commands with fingerprint. In case this is not automatically setup by KDE you can do: sudo pam-auth-update (use space bar to enable the "Fingerprint authentication") I enrolled two figerprints. Logging in after "lock" worked - almost: I had to press "enter" and then got a prompt to touch the fp device. That was ok. Then I tried to log out and log in -- and theh sytem is **now frozen**. I am unable to log in in any way I can think of!!! How can I revert to my working system, from 10 minutes ago? -- You are receiving this mail because: You are watching all bug changes.
