Linux mint failed to start light display manager

Arch Linux

Hello! I am pretty new to Arch and decided to run lightdm with xorg. After a reboot the message «[FAILED] Failed to start Light Display Manager.» shows up without any further information.

I have no clue why this suddenly started happening so I require some help. Here my lightdm debug log:

[решено] Не загружается Light display manager (lightdm)

Стал ставить щас обновления (+600мб с чем то) и как то сразу покоробилась паняль с меню и часами. Потом вообще перестала система отвечать и ушла в черный экран. Перезагружил но теперь пишет failed to start Light display manager (lightdm). Переключился в терминал 2 и попытался обновить там систему но она пишет что то про то что не может подключиться к базе данных пакмана. Пробовал переустановить этот lightdm но тоже не может. Останавливал и запуска демон тоже не помогло. Рнбят помогите спасти систему. Что можно сделать. startx тоже не запускает рабочий стол. Видеокарта у меня gtx 1060 6gb дрова были 4хх какие точно не помню а ядро 4.19.

запусти startx из терминала, если пустит, то дальше уже будешь лечить через gui

sudo rm /var/lib/pacman/db.lck

startx делал но не загружается рабочий стол. говорит типа нету доступа или что то типа этого. вернее написано много чего и в конце connection refused.

говорит типа нету доступа или что то типа этого. вернее написано много чего и в конце connection refused.

желательно увидеть, что конкретно говорит, скинь фото.
файл блокировки удалял, пакман заработал? если да, то
1. можно попробовать удалить lightdm-gtk-greeter и заново поставить

sudo pacman -R lightdm-gtk-greeter lightdm-gtk-greeter-settings

sudo pacman -S lightdm-gtk-greeter lightdm-gtk-greeter-settings

2. как запасной(экстренный) вариант, можно поставить другой дисплей менеджер, gdm, sddm — много их, а дальше уже разбираться с lightdm

помогло удаление /var/lib/pacman/db.lck и запуск полного обновления системы sudo pacman -Syyu
и после ребута все появилось. Спасибо.

Если проблема схожая объясните не много по подробнее пожалуйста.
