有几天，每次我启动 Ubuntu（18.04）时，都会收到一个警报窗口，声称系统程序出现了问题，而我唯一能选择的选项是发送通知或关闭警报。
由于不知道哪个应用程序出现了问题，而且我根本不是 Linux 专家，所以我想知道是否有办法找出哪个应用程序出现了问题，以便尝试以某种方式解决问题。
谢谢大家

所以，我尝试查看，/var/crash/但那里只有两个元素，而且都是三天前的，所以我认为与日常问题无关。所以我按照建议尝试了日志选项，但由于我无知无比，结果对我来说毫无意义。我在这里发布了其中的一部分，我认为这部分与时间码有关，希望有人能理解并向我解释。

ubuntu 崩溃报告存储在 /var/crash 中。
您可以执行“ls -l /var/crash/”来获取错误报告列表。
记下最新情况并查看是否可以解决该应用程序遇到的任何问题。
