I’ve been having trouble with the fingerprint sensor on my Framework 16, and I’ve noticed others with this same problem. When I first set it up, it seemed to work alright for the first few uses, but after that, it has been about a 80/20 chance whether it will actually authenticate, or if it will rapidly use up all of the attempts and I’ll just need to manually input my password. Has anyone else had this problem, or have a potential solution? I’ve also noticed that occasionally, at the login screen after closing the lid, the prompt for a fingerprint is missing.
I’m experiencing after some resumes, the fingerprint reader has timed out. Pressing enter on the password input field ( fails as expected as I’ve not entered the password ), the fingerprint reader is working again and this is only happening on resume
I think it’s a software issue, not sure where exactly yet.
Maybe a coincidence but since Linux 6.14-rc6, it’s been happening less frequently but I’ve also just updated linux firmware last night too
Could you update your post to show what linux firmware and desktop/gui environment your using
Same experience here with my FW13. I just gave up, deleted the fingerprints in settings, and type the password when prompted. Life’s too short to mess with or get frustrated by Ill-behaving machines.
I have a fingerprint sensor from the 11th gen Framework 13 that I am using. I have a 12th gen mainboard in there now and have installed at least 15 different OSes on it over 50 times. In all of that the fingerprint sensor has worked super reliably. I did have to clear saved prints when switching between some OSes but in general things worked the way they should.
I just did a quick experitment. My FW13 is setup dualboot F41/Win11. I setup fingerprint login in win11, it just works. It was quicker and easier to set up than in Fedora, and when logging in, a single light tap on the sensor un-locks the computer, boom done. None of the try, try again BS I was seeing in Fedora. So I’m thinking it is more of a Fedora issue.
I’ll keep fingerprint login active in win11 and see how it holds up. That will take some time, I don’t use win11 very often.
It’s been ~2weeks since I configured Win11 to use the fingerprint scanner. Things continue to work just fine. So I’m convinced that whatever Fedora 41 is doing is just problematic. When F42 is out and stable I’ll set up the fingerprint scanner again & see if it works any better.
I’m curious. What portion of the finger are you using?
Closer the to tip of the finger, the worse reliability I’ve had.
It’s kind of unnatural, but keeping the hand flat against the keyboard area and using the bottom of the finger works well for me.
The fingerprint sensor on my Laptop 13 seems about as good as the one on my Samsung Galaxy A51 and as the USB fingerprint reader on my other PC. In other words, not very good.
I assume all fingerprint sensors are pretty unreliable.
Waiting a while after powering on helps quite a lot for the initial login. That is, it seems better when the CPU isn’t too busy. Also, if my fingers are dry, and it’s not a hot day, then it works better if I blow hard on to my finger to slightly moisten it before using the fingerprint reader. The software will occasionally make you log in another way (with a PIN in my case) just so you don’t forget how to do it.
If none of that helps, try erasing your fingerprint(s) and setting up again.
Updated to Fedora 42 earlier this week, and setup the finger print reader. Works great, now. Setup was fiddlely, took several tries lift finger, place finger, failed to read finger…but once set up it is working fine (so far KOW), quick to read and unlock system, or authorize sudo commands. Seldom a failure to read.
A quick update on the Win11 set up, it failed to work a few days ago. Win11 “forgot” my pin, couldn’t read my finger print…etc. I’ve had that forgot pin stuff over time on other hardware, no clue why, Win11 just does stuff like that. If only Adobe would port LR to Linux …I could forget MS/Win11 forever.
For anyone that comes across this again, the issue is fixed for me. What I did was just adding another fingerprint. Originally I was using “Right Index Finger”, but I added a second entry under “Right Thumb” but just registered the same finger. Normally when you do this, it gives an error saying “Fingerprint is duplicate”. But, this time it just let me enroll the same finger again. After this, I have had no issues with the fingerprint reader. (Still on Fedora 41 at time of posting)
Long story short, I think Fedora may have been deleting the original fingerprint data for some reason. No clue why this happens.
