Bug ID: 505222 Summary: Fingerprint unlock rarely works after upgrade to Plasma 6.3.4 Classification: Plasma Product: plasmashell Version First 6.3.4 Reported In: Platform: Kubuntu OS: Linux Status: REPORTED Severity: normal Priority: NOR Component: Screen locking Assignee: plasma-b...@kde.org Reporter: mcar...@yahoo.co.uk Target Milestone: 1.0 SUMMARY With Kubuntu 24.10, I could lock the screen, leave it for a while, come back and unlock with fingerprint. After upgrading to Kubuntu 25.04, I can only log in with password in that case, but fingerprint works for sudo and sometimes works for immediate unlock after window-L lock. STEPS TO REPRODUCE 1. /etc/pam.d/kde looks like this: auth sufficient pam_fprintd.so auth sufficient pam_unix.so try_first_pass likeauth nullok Actually I have a slightly more sophisticated setup whereby login uses password and does not use the fingerprint (because it won't unlock KWallet) but screen lock and sudo use fingerprint first falling back on password. This is described in detail here: https://www.reddit.com/r/Kubuntu/comments/1aew6t3/comment/kodetid/?utm_source=share&utm_medium=web3x&utm_name=web3xcss&utm_term=1&utm_content=share_button 2. Test unlocking after sleep OBSERVED RESULT With Kubuntu 25.04 (Plasma 6.3.4), it doesn't work, but fingerprint for sudo works fine and window key-L to lock and immediate unlock sometimes works. EXPECTED RESULT With Kubuntu 24.10, it worked reliably ie. fingerprint works for immediate unlock and unlock after sleep as well as sudo.
