ASUS M50Vc with AuthenTec AES1600 fingerprint reader, Ubuntu 14.04.

Everything works normally EXCEPT when I need to unlock the screen after suspend. There is no prompt to swipe the finger, swiping doesn't do anything, if I try unlock with password, the "wait" indicator keeps rotating but screen won't get unlocked (it doesn't hang though, panel still accessible).

Has anyone had a similar issue? Any workaround suggestions?

@Pavel, I just came across the same issue with my ThinkPad X220 here, running Ubuntu 14.10. A temporary workaround for me is to switch to the (non-graphical) console, log in there with my password, kill the fingerprint-helper process and then switch back to the X-server console.

Steps are:

  1. Switch to the text console: Ctrl + Alt + F1
  2. Login with your regular username + password
  3. Shutdown the blocking process: killall fingerprint-helper
  4. Switch back to the X-server console: Alt + F7

If this is not sufficient, you might want to try killing fingerprint-polkit-agent as well, although it hasn't been necessary when I tried today.

Don't forget to log off from the text console again (press Ctrl + D), otherwise everyone else who has physical access to the machine will be able to use it!

  • I stopped using fingerprint login, will re-install & try again. – Pavel Jan 2 '15 at 11:43
  • Same behavior here with Thinkpad x230 (Upek Fingerprint reader 0x147e:2020) and Ubuntu 16.04.1 LTS. I also usually kill the fingerprint-helper as he1ix wrote when it hangs. But I have one question, do you use encrypted home filesystem with ecryptfs? I do. – Luckyrings Nov 17 '16 at 12:14

I have had similar issues, but just hitting enter after swiping my finger makes it work. Using a thinkpad x1 though (from 2011?), so might be different.
