今天我决定只测试kde-等离子体所以我把它安装在我的机器上，Ubuntu 20.04。 我怎样才能彻底删除它? 我已经尝试了下面所有的命令，但它的一些依赖项（如 Konsole）仍然存在于默认的 Ubuntu 桌面上。它还导致了一些问题，例如当我移动应用程序时，它就像出现了滞后。
sudo apt-get remove plasma-desktop
sudo apt-get autoremove
这一个也：
sudo tasksel remove kubuntu-desktop
答案1
我有同样的问题。
打开一个终端（不是 Konsole，可能是 gnome-terminal）
类型
sudo apt --purge remove 'kde*' konsole 'plasma*' 'kubuntu*' systemsettings ksudoku konversation ktorrent ksystemlog kmines kcalc partitionmanager 'gwenview*' 'kwallet*'进而
sudo apt autoremove重新启动系统
我认为这为我解决了问题
我在 Ubuntu 论坛上找到了一个完整的解决方案，来自这个帖子在彻底删除 KDE 桌面（我没有尝试过）：
