Thinkpad x220 - Fingerprint issue

Hi, i have a problem with my fingerprint reader on my Thinkpad x220. In fingerprint-gui seems to work fine. Scan fingers works, but when i test (in fingerprint-gui) sudo it doesent work. Fingerprint reader even didnt light up.
Sudo, Login didnt work.

Sorry for my bad english.

According to the Arch Wiki for X220, the fingerprint should work fine using fingerprint-gui.

Did you by any chance follow these instructions yet?


Is your fingerprint reader device from Elan Microtechnology, may I ask?

Hi, no its Upek (0x147e) (0x2016)

Hi, yes i followed instructions on ArchWiki.
