I'm seeing this also upon 17.10 upgrade in unity / lightdm / unity greeter.
It doesn't happen 100% of the time, typically takes some time time to manifest (I only ever suspend my laptop from monday to friday), but once it starts happening, it always happens until I shut down. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to lightdm in Ubuntu. https://bugs.launchpad.net/bugs/1733557 Title: Login screen showing Authentication Failed Switch to greeter...
