Screen lock on sleep

### What Happened?

When I put the system into sleep mode, the screen does not lock with password. Along with that, the blocking interface when turning on the computer is that of Ubuntu. After an update, the pantheon interface was switched to Ubuntu's and I believe this may be affecting the auto-sleep function.

### Steps to Reproduce

1. I restarted the system

2. Opened lock screen with Ubuntu interface

3. I waited as long as it took to go into auto-sleep mode

4. The screen just turned off, without password locking.

### Expected Behavior

I wanted it to go back to the old lock interface and auto-sleep also lock the screen with password.
