我有 Debian 10 和 KDE Plasma。有时，当我双击 KDE 中的图标来启动 Gnome 系统监视器时，它似乎已加载，然后立即关闭。当我尝试通过输入从命令行启动时
gnome-system-monitor
我明白了：
(gnome-system-monitor:3146): Gtk-WARNING **: 15:21:17.441: Theme parsing error: gtk.css:127:35: The style property GtkButton:child-displacement-x is deprecated and shouldn't be used anymore. It will be removed in a future version

我不确定它如何进入无法启动的状态，或者如何修复它以便它可以再次启动。我试过：
sudo killall gnome-system-monitor
并得到这个：
gnome-system-monitor: no process found
答案1
我能够通过以下方式修复它：
- 右键单击启动器中的应用程序
- 单击编辑应用程序
- 单击应用程序选项卡
- 单击高级选项
- 单击以其他用户身份运行
- 输入“根”
我现在可以在 KDE 中再次启动它。
