openshot 团队的一名成员正在帮助我解决问题，突然间所有图形都变成了 Windows 3.1。他帮助我重新安装了 gnome，但一些问题尚未解决。此外，相当多的程序消失了，我不得不下载它们。
如下所示，终端看起来很“旧”。以前它很漂亮，是紫色的。右上角有一个汉堡菜单。现在各种图标看起来也很老式，但有些东西已经恢复正常了。抱歉，我没有更多信息，我只是盲目地听从了他的建议，不记得到底发生了什么。

该终端根本不是 GNOME 终端。它看起来像是来自 LXQt 桌面环境的终端。
sudo apt install gnome-terminal
sudo apt remove qterminal
我还看到了 Discover，这是 KDE Plasma 桌面环境中的应用商店。看起来你混合了一堆 DE，这是不推荐的，你可能需要用
sudo apt remove plasma-discover
我认为您可能还重新安装了普通的 GNOME 软件应用程序，而不是 Canonical 为支持快照而创建的变体。
sudo apt remove gnome-software
sudo snap install snap-store
您还可以尝试以下命令：
sudo apt remove kubuntu-desktop
sudo apt autoremove
