Greeter, кажется, работает, но перезапускается сразу после входа пользователя / pw при новой установке Xubuntu 18.04 - proUbuntu

Lightdm отказывается разрешить мне войти в систему с новой установкой Xubuntu 18.04. После того, как я ввел свое имя пользователя и пароль, вместо входа в систему экран пропадает, и вновь появляется приветствующий. Я озадачен этим циклом входа в систему; Я не вижу ничего плохого. Пароль и пользователь хороши. Разрешения правильные; ssh работает так же, как и консольный вход в систему, но приветствующий - нет. Во время каждого цикла в /var/log/syslog появляются следующие строки:

Fixed. Проблема заключалась в том, что файл .ICEAuthority пользователя при входе принадлежал пользователю root.

Но мне интересно, как это случилось. Я проверил ранее, и я не видел эту ситуацию, и с тех пор я сделал обновление. Наименьшая гипотеза, конечно, заключается в том, что я допустил какую-то ошибку. Я обнаружил проблему, перепроверив .xsession-errors пользователя, но уже это проверил.
