Occasionally gdm login comes up without a user

[Matvey Teplov]

From time to time after locking the station, the GDM login screen comes up without a user, but with the password prompt. At this time login fails at a 100% rate. Recovery is to cancel the login by escaping (ESC key) and re-trying again until the user name is displayed. There is a single known login-enabled user in the system.

Hi,

Yes, pretty much the same with one exception - there is no generic user
shown, but just a password prompt.
