When I turn on the computer, the desktop usually promptly appears. It has entered the emergency mode for some time. So I write systemcl default and everything is okay. But, just out of curiosity, I want to know why it happens. It seems that the emergence mode is the default option but I don't know why. Also wanna change it.
All the best.
