stuck in fingerprint authentication

rated 0 times [ 2] [ 0] / answers: 1 / hits: 480 / 1 Year ago, wed, december 21, 2022, 4:02:31

I have updated my Thinkpad T490 laptop to Ubuntu 22.04. Everything went fine.

After the update I have activated the fingerprint to login and... I can not login anymore.

When I click on my user name on the login screen, I briefly (less than 0.5 sec) see the place where I should be able to write my password. I can read the error message "Sorry, fingerprint authentication did not work. Please try again"and then it goes back to the login screen with the name of my user.
I can still access to a terminal using Ctrl + Alt + F5.

Does anyone have an idea on how to solve this problem?

Is there a way to disable fingerprint authentication from command line?

I'm having the same problem on my ThinkPad X230T. The workaround is to remove the fingerprint service. So after log-in into a TTY (Ctrl + Alt + F3-F5) you can do that by the command:

sudo apt remove fprintd

Disabling and stopping the service didn't solve the problem in my case because a few reboots later for some reason it was enabled again.

I haven't investigated yet why it doesn't work as it is expected.
