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 ProblemType: Bug DistroRelease: Ubuntu 14.10 Package: lightdm 1.12.1-0ubuntu1 ProcVersionSignature: Ubuntu 3.16.0-30.40-generic 3.16.7-ckt3 Uname: Linux 3.16.0-30-generic x86_64 ApportVersion: 2.14.7-0ubuntu8.1 Architecture: amd64 CurrentDesktop: Unity Date: Sat Feb 7 23:54:05 2015 InstallationDate: Installed on 2015-02-03 (4 days ago) InstallationMedia: Ubuntu 14.10 "Utopic Unicorn" - Release amd64 (20141022.1) SourcePackage: lightdm UpgradeStatus: No upgrade log present (probably fresh install) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/lightdm/+bug/1419369/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : desktop-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
