I have installed Elementary OS Hera on Macbook Air from 2010.

It works quite nice but one of the issues I noticed lately is that it doesn't go to sleep but just locks the screen and displays login screen until it is closed.

I configured it to turn off the display after 5 minutes of inactivity and sleeping after 10 minutes. I wanted to have some time after the screen turns off to wake it without having to provide the password.

But instead of going to sleep it "turns on" but locks the screen and stays that way for a long time, until the lid is closed.

This is the screenshot of power settings. Those are in Polish but the placing is the same in other language versions, I hope so.

Here are the relevant entries from kern.log. It seems to be going to sleep and then immediately waking but I don't know what is waking it up. There seems to be some error from WiFi.
