Hello everyone, I want to wish you a happy new year.

After the last update I made of the distribution for 2019.4 I realized that the lock screen now lists the users and I already came across my users who had.

But my root was not listed, so far so good.
When selecting login with another unlisted user, in root case, when entering passwd, I get the message that my password does not match. Not believing that, I joined another user.

In this other user, I can elevate the privileges on the terminal using root, but I can not unlock on the login screen.

What can I do to solve this?
I tried to change the password, access another Xfe interface, but so far nothing successful.
