It's easy to reproduce:
- log in an uptodate xenial system
- start a guest session
- close it
-> the greeter only has the custom a11y indicator
Looking a bit more it seems the greeter session bus fails to start which makes indicators to bail out (there is an error in the greeter log "Failed to launch bus: Failed to connect to session bus"), it also makes unity-settings-daemon not work properly it seems (resolution is wrong when screen configs change)
Robert, could you have a look to that issue?
