对我使用的指纹读取器设备（04f3:0c58 Elan MicroElectronics Corp. ELAN:Fingerprint）的支持可根据这页面，但当我尝试运行时，fprintd-enroll我总是得到以下结果之一：
1.
$ sudo fprintd-enroll
[sudo] password for sbeve72:
Using device /net/reactivated/Fprint/Device/0
Enrolling right-index-finger finger.
Enroll result: enroll-disconnected
$ sudo fprintd-enroll -f left-index-finger
Using device /net/reactivated/Fprint/Device/0
Enrolling left-index-finger finger.
Enroll result: enroll-stage-passed
Enroll result: enroll-unknown-error
或者它只是卡在
$ sudo fprintd-enroll
Using device /net/reactivated/Fprint/Device/0
Enrolling right-index-finger finger.
在我按下 Ctrl + C 之前什么也没有发生。
在最好的情况下，有时我会得到
$ sudo fprintd-enroll -f left-index-finger
Using device /net/reactivated/Fprint/Device/0
Enrolling left-index-finger finger.
Enroll result: enroll-stage-passed
Enroll result: enroll-stage-passed
Enroll result: enroll-stage-passed
Enroll result: enroll-stage-passed
Enroll result: enroll-completed
但要么enroll-verify给出这个：
$ sudo fprintd-verify
Using device /net/reactivated/Fprint/Device/0
Listing enrolled fingers:
- #0: right-index-finger
Verify started!
Verifying: right-index-finger
Verify result: verify-no-match (done)
或陷入困境
$ sudo fprintd-verify
Using device /net/reactivated/Fprint/Device/0
Listing enrolled fingers:
- #0: right-index-finger
- #1: left-index-finger
Verify started!
Verifying: right-index-finger
