That's unlikely to be an fprintd bug. Please try and debug this on the LightDM side with your distribution first, and file a bug here when you have a reproducer.
Seems to me that LightDM is using a single PAM conversation for both pam_fprintd and the normal password checks. This isn't something that we can fix in pam_fprintd, and LightDM will have to work-around the PAM limitations. Reopen the bug when you've debugged the LightDM side of things. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1300462 Title: Login timed out after waking from suspend To manage notifications about this bug go to: https://bugs.launchpad.net/fprintd/+bug/1300462/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
