我在使用 kde 5.9 时遇到问题，任务栏不再显示。桌面壁纸是黑色的。我仍然可以使用 CTrl+F2 打开应用程序。我尝试了一些命令，得到了以下信息：
关于如何再次显示任务栏有什么想法吗？
提前感谢

首先，尝试重新启动 Plasmashell。
在克兰纳， 跑步：
kquitapp5 plasmashell && kstart5 plasmashell
您能提供更多详细信息吗？发行版？显卡？开源驱动程序还是专有驱动程序？

答案3
我已经成为活跃的 KDE 会员一年了......
但在与管理员多次讨论后，他们拒绝修复 KDE 崩溃问题。我不得不退出这个自私的社区。
目前，我在最新的 KDE 中使用 Debian 11.4 对其进行了测试：
- 在黑屏壁纸上按下
Ctrl+Alt+ ，将打开 Konsole。输入：t
~$ rm .config/plasma-org.kde.plasma.desktop-appletsrc
现在你可以测试它：
killall plasmashell
plasmashell
但我建议你重新启动计算机。
答案4
尝试plasma-desktop在命令行中运行。这对我有用。
