安装了 ubuntu 14.04 并且系统每天至少会在随机时间冻结一次。
冻结是指鼠标键盘和屏幕完全没有反应。无论系统处于 还是处于空闲状态且锁屏开启，都会发生这种情况。
我每次都必须按住台式机 (powerwash) 的电源按钮才能重新启动。
在我的日志 var/logs/syslog 中，屏幕冻结后似乎仍有进程在运行。考虑到已完成的任务，我认为系统最后一次冻结的时间在 11 到 12 之间。12:50 是我重新启动桌面的时间。
如果有人能在我的系统日志中看到问题或告诉我在哪里可以找到它，那将非常有帮助。我甚至不知道从哪里开始。

尝试在以下帮助下进行故障排除这里。
答案2
Alt+ Ctrl+F1会带您进入功能齐全的命令行界面，您可以登录并执行任何您想做的事情。它比 Ubuntu 的图形部分稳定得多。 Alt+ Ctrl+F7会带您返回图形界面。
尽管 GUI 冻结，您仍然可以使用命令行界面。这使您能够更好地诊断系统。您可以杀有问题的流程。 重启 Xserver可以暂时解决问题。在最坏的情况下，你可以安全地关闭你的电脑。
