Док-станция по умолчанию заменена док-станцией типа «тире-в-док»

У меня была такая же проблема. Оказывается, они хранятся в gsettings. Таким образом, чтобы вернуться к состоянию Ubuntu Dock по умолчанию, вы можете сбросить все связанные свойства:

Вы можете использовать следующую команду:

$ dconf reset -f /org/gnome/shell/extensions/dash-to-dock/

Но сначала вам нужно убедиться, что у вас установлен dconf-editor. Если вы этого не сделаете, вы можете просто получить его:

$ sudo apt update
$ sudo apt install dconf-editor
