[Bug 1419369] [NEW] Fingerprint reader doesn't work after suspend

 

Public bug reported:

My fingerprint reader does not work after "waking up" my laptop.
This happens on both fingeprint GUI as well as fprint.
There is a workaround for fprint, fingeprint GUI crashed everytime. Had to uninstall.

Steps to reproduce when using fprint:
- go into suspend mode
- resume
- lightdm greeter says "swipe your finger…"
- nothing happens when swiping

- Wait until time out -

- lightdm asks for password
- press enter (without entering any password)
- lightdm says again "swipe your finger…"
- now it works
