I have a Lenovo IdeaPad 14ARE05 and have installed Debian SID on it. There were multiple compatibility issues out-of-the-box, but I've been able to resolve most of them. The only major one that remains is the fingerprint sensor.

Bus 003 Device 002: ID 04f3:0c4d Elan Microelectronics Corp. ELAN:Fingerprint

The sensor is detected by fprintd and finger seems to get successfully registered. However, during login, the fingerprint never matches. Is there a way to check if sensor is malfunctioning?


fprintd has a set of tools that, among other things, let you to check if everything is working before you try the login. I think the description for fprind-verify is wrong (it is probably what you want to try), but I'm quoting.


fprintd-enroll Will enroll the user's right index finger into the database.

fprintd-list Will list the user's enrolled fingerprints.

fprintd-verify Will enroll the user's right index finger into the database.

fprintd-delete Will delete user's fingerprint data

  • fprintd-verify also says Match Unsuccessful. But the same sensor is working perfectly in Windows 10 Jan 9 '21 at 3:01
