它们从 gnome-panel 中的指示器小程序中消失了，没有询问我任何内容，也没有通知我。我该如何在 11.04 中将它们恢复？我已重新启动，但情况仍然存在。
功能仍然存在，但没有图标。只有连接到 wifi 后才会出现连接图标（代表波浪的那些线），但从来没有显示没有 wifi 连接的图标。奇怪！
编辑。-我找到了这个日志文件：
/home/user/.cache/indicator-applet-complete.log
它的修改日期是最近的，并且经过一些测试，我认为每次我在小程序上生成事件时都会生成它。

但我不知道如何使用它来修复该问题。它提到缺少图标文件和断开的链接，因为该目录中只有 .svg 文件、指向 .svg 文件的链接、指向 .svg 文件的断开链接，而且似乎还缺少 .svg 文件。
如何解决这个问题，以及如何知道周围其他地方是否存在更重要的问题？
