问题描述
当我今天启动我的机器时，我的系统日志中收到了一些非常奇怪的消息：
...

Aug 17 18:58:15 Floral-Towel systemd[1349]: Starting Default.

...
我在那个时候包含了一些其他消息，以防它们在某种程度上可能有所帮助。但要达到这一点，谁或什么是“失败的鲸鱼”？为什么他/她/它死了？这一切是什么意思？它在我的系统日志中有什么作用？
我正在使用Gnome Shell和Gnome 3.16运行Ubuntu Gnome 15.04。

最佳解决思路
在这种情况下，如果出现问题，”fail whale”是GNOME记录的错误消息。它以Twitter使用的illustration by Yiying Lu命名，以显示错误。
如果它已经死了，则意味着没有足够的GNOME运行来显示错误。
