I’m using Fedora 37 Workstation (upgraded from Fedora 36), and I’ve never been able to add a fingerprint. The settings app responds when I place a finder on the reader (the fingerprint icon changes color), but nothing happens. When I remove my finger, it often says “Place your finger on the reader again.”
How long are you holding your finger on the reader? The UI is a bit strange - I had to hold my finger on it until the icon changed back from being blue, then do it again a number of times (there was no prompt to do this).
Hmm, I’ve held it on for up to 30 seconds before. I just tried doing about 10 lifts and presses in a row, and then I got a message saying the fingerprint device was disconnected, and now I’m getting a message at the top of the window saying the device is already claimed by another process.
I never did get it working. I tried just now, and it seemed like it successfully enrolled my fingerprints for the first time. When I logged out and put my finger on the reader to log in, however, it immediately said something about not recognizing it as a registered fingerprint and removed the fingerprint data and the option to login that way. After using a password to log in, it’s now failing to enroll my fingerprints again.
I’ve been using this appimage to address issues like this. I’ve also reached out to the creator to better understand how it works. Basically it clears the fingerprint device and gets it “unstuck”. It’s supposed to be including in libfprint from what I was told, but it may not be there yet.
