LinuxQuestions.org - [SOLVED] root: login incorrect

Good time!
Excuse my bad English.
Arose the following errors. Upgrade to version 13.1, now I can not register in the virtual console as “root”.
But if I sign in to the virtual console as normal user -> run a terminal emulator, then use «su», I did it change the user to «root».
I tried to change the password, the result is the same.

part of the log:

Code:

May 27 12:26:54 antidote login[1777]: exceeded failure limit for 'root' on '/dev/tty6'

May 27 12:27:01 antidote login[1777]: exceeded failure limit for 'root' on '/dev/tty6'

/etc/securetty:

Code:

# This file defines which devices root can log in on.



# These are the ttys on the physical console:

console

tty1

tty2

tty3

tty4

tty5

tty6

#...

/etc/login.defs:
-Comments with descriptions of parameters removed-
