Can't login from lock screen on Xfce

I cannot log in to my laptop when the screen is locked, both automatically or manually. When i type my password from lock screen it says, password incorrect.

I have auto-login enabled. I can use my system properly in the terminal, pamac, etc with the same password without issues.

Even tty2 not working when the screen is locked, it says "Authentication failure"

This happened suddenly and I am not sure what caused this.
Can anyone help?

Hi,

I'm assuming you set one password for both root and user account. Or do you have two different passwords for each account.?

If a new install, lightdm does have an annoying habit of showing "Dynamic User" rather than your usual login name. Until things settle down after post updates and configuring.

When using TTY, it asks for your login user-name, first, then password.

If any of the above suggestions fail, press Ctrl+Alt+Delete to reboot your system and investigate Power Settings and Screen Saver in Xfce system settings.

If your setting seem correct or to your satisfaction, but still experience issues run this command inxi -Fxzc0 so you may be able find the right advice.

:wink:

Yes when installig I set same password for both..

It's been more than a week and system is updated, it was working properly couple of days ago

Yes, I have provided both

I can only suggest a temporary solution, but it will require someone who has experienced this issue first hand to guide you.

Go to Power Manager:

General - When laptop lid is closed "Lock screen" change to "Switch of screen"

Security - "Never" Automatically lock the session and unclick "Lock screen when system is going to sleep".
