HN 提问：您如何排查桌面 Linux 崩溃/冻结的问题？
2 分•作者: Curiositry•3 个月前
我一生都在使用 Linux。我很想说它很稳定，但我的经历并非如此 :) 所以我想提高从冻结和崩溃中恢复的能力，并找出根本原因。
我大量使用 Ctrl+Alt+f3，以及 Magic System Request 键（Ctrl+Alt+PrtSc+f；Ctrl+Alt+PrtSc+reisub）。但很多时候系统已经损坏到无法切换到虚拟终端。在这些情况下，我通常会尝试在 dmesg/syslog/journalctl 中寻找线索。
大部分问题似乎是由 Nvidia GPU 和挂起引起的。
你常用的恢复命令是什么？当这些方法无效时，重启后你如何进行事后分析？
