Позвольте новому пользователю получать доступ/использовать/требовать к дому старого пользователя

У меня были проблемы цикла входа в систему с учетной записью пользователя, user1, таким образом, я создал нового администратора user2 с полными правами.

Существует ли простой способ просто ИСПОЛЬЗОВАТЬ среду старого user1 для нового user2?

Идеально я удалил бы user1 из входа в систему, и user2 будет иметь корневой каталог user1?

Я надеюсь, что это легко и решит циклы входа в систему. User2 не имеет цикла входа в систему прямо сейчас.

Вот некоторые надрезы из Auth.log от Ken (user2) и rb1888 (user1). Я вижу, что user1 не имеет systemd: pan_unix(systemd-user:session) в нем, поскольку user2 делает и не имеет никакой проблемы при входе в систему и ПРЕБЫВАНИИ в GUI.
