I used fprintd to try and register my fingerprints. I then realized I had registered different fingerprints as the same fingerprint (mis-calling the tool) so I decided to nuke the fprintd information rm -r /var/lib/fprintd and try again.
Except now every time I try to scan my finger, it fails.
Is there a call I can make to reset the fingerprint database? I have some confidence that’s the problem since I don’t get this problem on fingers on my left hand (I only had scanned in my right hand).
Users could probably replicate by registering fingerprints and then re-installing Linux.
I am not sure the windows suggestion would work for me even if I had a copy around, since the fingerprint DB wouldn’t be on a windows install. In fact I assume I did the equivalent by removing /var/lib/fprintd, didn’t I?
As @nrp noted, there is an fprintd-delete utility. However, it may be useful to see if fprintd-list works first since that shouldn’t be a destructive command.
I am booting garuda linux on one drive and windows 10 on another, when I enrolled my finger in windows I have lost the ability to sign in on linux, it seems to only be accepting my finer as an option, not my password? Help please.
EDIT:
Once I figured out how to get into text mode I could sign in and deal with fprintd, first though I had to go to windows to delete the enrolled fingerprints as described in the link posted by nrp earlier in the thread: Accidentally breaking the fingerprint reader (software) - #2 by nrp
