p.s. если мне нужно проделать какие то действия, то попрошу, чтобы вы уточнили как это делается. linux-ом пользуюсь около месяца.
p.s. раньше стоял lxdm. работает нормально, но захотелось перейти на этот из-за оформления. изменение менеджера осуществлялся командой
#systemctl enable -f lightdm.service
до включения так же был протестирован. если нужно вот результат.

lightdm-gtk-greeter поставили?

lightdm-gtk-greeter поставили?
Спасибо большое. Очень помогли)
Но помимо него есть ещё пакет webkit2, установленный из aur. Даже если поменять пункт в конфигурации лайта, тема не меняется

есть ещё пакет webkit2
А это здесь при чем? У lightdm этого пакета в зависимостях нет.
In Tux We Trust
redix
webkit2
А это здесь при чем? У lightdm этого пакета в зависимостях нет
Наверно имелся ввиду lightdm-webkit2-greeter

webkit2, установленный из aur. Даже если поменять пункт в конфигурации лайта, тема не меняется

Может ошибка в конфиге /etc/lightdm/lightdm.conf
Должно быть (не забудьте решетку #убрать)
greeter-session=lightdm-webkit2-greeter

темы еще можно поставить
lightdm-webkit2-theme-material2
lightdm-webkit-theme-archlinux
или что подобное

А может webkit2-greeter збоит и поэтому грузится по умолчанию gtk
посмотреть что выводит lightdm --test-mode --debug
