many thanks for the file - I've been able to reinstall lipstick, and it worked (the install) as my lockscreen now doesn't show the calendar anymore .... but ... the login screen still shows only the background - no dialer buttons ... so I'm still locked out ... is there by any chance a possibility to disable the login from the terminal - As I have to unlock it in the Terminal anyway it won't be a security flaw if it's possible ..

or any other ideas?
