Comment 4 for bug 1300462

I'm using fprint package for finger-print authentication on Ubuntu 14.04.
It's working perfectly for most things.

Some of the time when my laptop recovers from suspend, I am able to enter a password (or, after pressing Enter, a finger print instead).
But much of the time when it recovers from suspend, the lightdm (?) login screen instead says that authentication has timed out. For some reason I then have to wait a good 25 seconds before I get another chance. At that point, I am able to enter a password or fingerprint as normal.

When this problem occurs (most of the time), the machine wakes without the fingerprint sensor activated (no light), but the login gui screen prompt says something like "swipe your finger". It very quickly gives up, and then says Authentication Timed Out and makes me wait a LONG time. Note that during this time, no other users are listed on the lightdm login screen, so I cannot click on another user or guest to log in.

This "time out" should not be triggered during/after a suspend.
Also, if there is a time out for some reason, it should just wait the normal 2 seconds required after entering an incorrect password.

I'm posting this here because it seems to be the fact that the fingerprint scanner is somehow unavailable after waking, and maybe it is fprintd that times out the authentication for so long.
