Unity 错误：未找到默认装饰，放置位置不正确

在终端中输入 unity 来重置我的顶部任务栏后，它可以正确加载，但我在终端中得到了这个堆栈跟踪：

它仍然运行良好，但我想知道这是怎么回事。

谢谢

compiz (decor) - Warn: No default decoration found, placement will not be correct

让我们分析一下开膛手杰克：

  1. 消息来自compiz
  2. 该插件是装饰插件（因为 compiz 使用插件所以叫插件）
  3. 该消息是警告ing，意思是：某事不存在“好的”但显然我们仍然可以这样工作
  4. 原因排在最后，由于某种原因，compiz 没有找到默认装饰，因此窗口装饰的位置也许不会准确（即所谓的视觉故障）。

那么，是什么告诉你这一点的呢？几乎没有什么，可能是您应该在 compiz 和修复中追踪的配置错误，也可能是 Unity 故障。无论哪种情况，您都应该将其报告给他们的开发人员并获得进一步的指导。
