答案1
/var/log/Xorg.0.log.old如果您在恢复后再次登录，您应该希望在或 的末尾看到崩溃消息$HOME/.local/share/xorg/Xorg.0.log.old。也就是说，在您上次登录的 Xorg 日志文件中。
Ubuntu 18.04 上有一个特定的已知问题，我认为它符合你描述的一切。它会在许多不同位置产生崩溃，但它也有一个相当独特的特点。崩溃总是伴随着 SIGBUS 信号（“总线错误”）发生，这很不寻常（在常见的 Intel/AMD 风格的 x86 CPU 上）。
大多数崩溃都是由信号 SIGSEGV（“段错误”）或 SIGABRT（断言失败/中止）引起的。SIGSEGV 是访问空指针或野指针的常见错误，尤其是在 x86 上。请注意，对于 x86 上的 SIGSEGV，Linux 会记录“段错误”消息，该消息会出现在系统日志中。此 SIGBUS 崩溃通常不会在系统日志中留下明显的签名！所以我已经怀疑这个已知问题了。由于您正在使用受此严重错误影响的软件，我建议您查看它，看看是否可以通过测试建议的解决方法之一来排除它。但我不确定这是否回答了您问题的一般含义。
有几条不同的消息有时发生此 SIGBUS 崩溃时。如果您愿意，您可以搜索所有历史日志，看看是否有任何“交换设备上的读取错误”或任何“缓冲区 I/O 错误”。例如zgrep -C5 /var/log/kern* "Read-error"。
请注意，Xorg 会记录自己的崩溃，但这对于软件来说并不常见。它会尝试捕获崩溃，记录崩溃信号以及它们在代码中发生的位置，包括导致崩溃的完整函数调用链。 理论上，调用链可能对搜索其他报告有用。 不幸的是，当我尝试依赖它时，Xorg 记录的调用链似乎不准确，并且对于实际上不同的问题看起来基本相同。
要捕获崩溃位置，使用通用系统（如 Ubuntu Apport 或 systemd-coredump）更可靠。我熟悉后者。如果您安装了systemd-coredump它，它将捕获崩溃的完整核心转储并允许您使用检查它们coredumpctl。但是，安装 systemd-coredump 会删除 Ubuntu Apport。
不幸的是，我不使用 Ubuntu，而且我对 Apport 的行为知之甚少。我读到完整的 Ubuntu Apport 在稳定版本上默认不启用。具体来说，我认为稳定版本不启用允许您创建可在开放网络上搜索的错误报告的功能。显然，启用它会比使用 花费更多时间Xorg.log，并且会减少使用此方法报告的人数。因此，如果Xorg.log信息不是 100% 准确，但清楚的Xorg.log，即使这些信息并不准确，您使用这些信息搜索事故报告也可能会更幸运。
答案2
这肯定是 NVIDIA 驱动程序或 NVIDIA 专有驱动程序与 Ubuntu 内核的兼容性问题。
我的笔记本电脑上有 NVIDIA 740M GPU，我也遇到了同样的问题。每当我放下笔记本电脑盖或暂停笔记本电脑时，恢复 X 时都会无法打开。有时它会显示类似
GPU 从总线上掉下来了。
但当我从 BIOS 关闭 NVIDIA GPU 时，我能够顺利暂停和恢复操作系统
