Проблемы с sddm: отсутствует sddm.conf, не работает sddm sddm-kcm, случайные проблемы с baloo

Системные спецификации, отформатированные для удобства чтения. Я добавлю, какие пакеты, связанные с плазмой, у меня внизу, потому что они довольно длинные

Я могу войти в систему в порядке. GPU установлен на мой 960M GPU, протестирован как активный GPU, а Nouveau не занесен в черный список. Проблемы - это графические глюки, ошибка Baloo, невозможность установить темы и проблема со стабильностью системы, которую я не получил после 4.15. Переустановка sddm не помогает.

Выход из sddm sddm-kcm:

Выдача sudo sddm sddm-kcm зависает, и требует, чтобы я взял на себя ответственность за мои файлы конфигурации, в противном случае у меня возникают проблемы с интерфейсом. Выполнение этих команд в TTY с service sddm stop возвращает отображение не найдено, что является данным.

Мне также не хватает файлов, упомянутых в man sddm.conf:

visitor@visitor-69:~$  /usr/lib/sddm/sddm.conf.d
bash: /usr/lib/sddm/sddm.conf.d: No such file or directory
visitor@visitor-69:~$ /etc/sddm.conf.d
bash: /etc/sddm.conf.d: No such file or directory
visitor@visitor-69:~$ /etc/sddm.conf
bash: /etc/sddm.conf: No such file or directory
visitor@visitor-69:~$ 

Бег whereis sddm.conf возвращает:

sddm: / usr / bin / sddm / usr / lib / x86_64-linux-gnu / sddm / etc / sddm / usr / share / sddm /usr/share/man/man1/sddm.1.gz

Жирный для видимости.

/ usr / bin / sddm: первый результат - приложение.

/ usr / lib / x86_64-linux-gnu / sddm: каталог, содержащий файл, известный как sddm-helper и возвращает ту же ошибку при запуске sddm sddm-helper ,

/etc/sddm: содержит один файл, Xsession, который я добавлю внизу.

/ usr / share / sddm: содержит сессию wayland Xsession Xsetup Xstop

/usr/share/man/man1/sddm.1.gz: содержит один.conf, который я предполагаю по умолчанию. Я хотел бы знать, должен ли я использовать это, чтобы заменить все мои отсутствующие sddm.confs.

Вот пример:
