我刚刚升级到 Ubuntu 20.04.1，重新启动后出现黑屏，光标闪烁（但无法输入）。

来自Xorg.0.log：

以下是文件开头的一些版本信息：

任何想法如何解决它/获取更多信息？我不介意简单地降级 ubuntu，但我读到降级也不一定是个好主意。

我发现了这个错误，它看起来有点相关。但我不知道如何恢复台面，或者这是否真的是原因。

我的机器是运行 Ubuntu Server 20.04 的 HP ProDesk 400 G4 SFF。

它在原来的 Intel i5-6500 CPU 上运行良好，但升级到 i7-6700 后系统将不再启动。

我试过进入救援模式和紧急模式，但它们都不会真正启动系统。有任何想法吗？

编辑：我也无法从 USB 驱动器上的安装媒体启动。以下是启动失败的屏幕截图：

启动问题

我今天在我的机器上关闭了 Ubuntu 18.04.4，稍后再冷启动它。现在它开始但不再到达 UI 阶段。启动过程以屏幕上的以下输出结束（输出的尾部）：

...
[  OK  ] Started Hostname Service.
[  OK  ] Started Network Manager.
         Starting Network Manager Wait Online...
[  OK  ] Reached target Network.
         Starting Permit User Sessions...

[  OK  ] Started Disk Manager.
[  OK  ] Started LSB: Speech Dispatcher.
[  OK  ] Started LSB: Record successful boot for GRUB.
[  OK  ] Started LSB: automatic crash report generation.

注意：当我重新开始时，shell 输出的顺序会有所不同。

我唯一能做的就是按下POWER按钮。结果 Ubuntu 关闭了。

GRUB 和恢复模式

我在启动时按右键进入了 GRUB (2.02) SHIFT。

我正在使用 Linux 4.15.0.-112-generic。还有4.15.0.-111-generic, 4.2.0.-42-generic, 4.2.0.-41-generic, 3.13.0.-64-generic, ... 可用。

当我选择时4.15.0.-112-generic (recovery mode)，启动过程不会进一步。但我到了Recovery menu: filesystem state: read-only).

恢复菜单

当我选择时，Resume normal boot我会进入通常的 UI 登录。

我调查/var/log/apt/history.log并发现了这些：

错误提交

建议的后续步骤

我怀疑启动问题是由最近的软件包更新引起的。我可能不小心安装了部分软件包Software Updater，因为我记得窗口中有一个警告。使系统恢复稳定状态的最佳方法是什么？

有关的

一步一步的解决方案

  1. 由于“mesa”发生分段错误，我删除了上面列出的history.logsudo apt-get remove mesa-vdpau-drivers:amd64 mesa-va-drivers:amd64 libegl1-mesa-dev:amd64 mesa-common-dev:amd64 libglapi-mesa:amd64 libgl1-mesa-dri:amd64 libglx-mesa0:amd64中发生的所有包。结果 Ubuntu 开始进入 shell 提示符。
  2. 然后我尝试安装一些最新的“mesa”包。我找到了ppa:kisak/kisak-mesa并通过sudo add-apt-repository ppa:kisak/kisak-mesa && sudo apt-get update.
  3. 然后我在sudo apt-get install mesa-utils libglu1-mesa-dev xserver-xorg-video-all不知道需要什么的情况下通过安装。

仍然 UI 没有启动。

  1. 然后我查看/var/log/dpkg.log并看到gdm3:amd64（GNOME 显示管理器）已被删除。我安装了它，重新启动，幸运的是可以再次登录。

但是桌面是空的，我无法启动任何文件夹。

  1. 然后我重新安装nautilus并在注销并再次打开后重新出现桌面（图标和文件夹）。

基本上就是这样。

我不断收到这些奇怪的 Firefox 段错误。每次我在挂起后打开笔记本电脑的盖子时，Firefox 都会冻结，只有强制退出有帮助。

这已经在几周前开始了。

当我做dmesg | grep segfault，我收到与“Cameras IPC”相关的错误。

这可能是什么？

Firefox 会尝试访问我的网络摄像头吗？

以下是错误消息：

最近我在我的笔记本电脑（Dell Precision M4700，16GB RAM）上安装了 Ubuntu 18.04.1，目前它非常纯净。问题是 Evince 3.30.0 在启动时会产生分段错误（核心转储）。自从安装了系统并且清除和重新安装（也通过 Synaptic）没有帮助后，它就发生了。任何想法如何使它工作？

我进入了

~/.local/share/gnome-shell

检查扩展文件夹中的内容 - 它发生了，没有这样的文件夹（根本没有文件夹），/gnome-shell 中的 'ls' 产生：

application_state

切换到另一个（新创建的）用户并在那里运行 Evince 会产生相同的结果。

运行 sudo debsums -s 提供的输出：

debsums: changed file /usr/share/X11/xkb/symbols/pl (from xkb-data package)

这是我手动编辑的文件。将其替换为原始文件（并删除我创建的新用户）我从终端中运行 evince 获得了更多输出：

Attempting to read the recently used resources file at 
'/home/january/.local/share/recently-used.xbel', but the parser failed:
Failed to open file “/home/january/.local/share/recently-used.xbel”: 
Permission denied.
Segmentation fault (core dumped)

该文件对我的用户有读写权限，但对我的组没有权限。我编辑了这些权限，为我的小组提供读写权限，现在Segmentation fault就像我之前运行 Evince 时一样。

我还使用 Synaptic 再次清除了 Evince 以安装版本3.28.2-1（通过 Synaptic）。首先，当我Apply尝试再次安装 Evince 时使用 GUI 按钮时遇到错误：

E: Unable to correct problems, you have held broken packages.
E: Error, pkgProblemResolver::Resolve generated breaks, this may be caused by held packages.
E: Unable to correct dependencies
E: Unable to lock the download directory.

当我选择Edit->Apply Marked Changes. 运行 Evince 时重新安装仍会产生 Seg.fault。

运行sudo evince我得到：

No protocol specified
Unable to init server: Could not connect: Connection refused
Cannot parse arguments: Cannot open display:

由于事情是随机发生的，有时我设法从 GUI 中的 evince 中得到一个错误（你会称之为飞溅吗？），抱歉它太大了，我想包含所有可能的数据。

fsck在恢复根命令行中运行没有产生错误。

几天前我做了memtest，然后我做了一个fsck，收到了这个结果：

我在 gnome-shell 中遇到了很多 segv 崩溃，虽然 apport 窗口有很多信息，但它对用户不是很友好（窗口非常小，无法搜索，无法将副本保存到文本文件等） .

有没有办法可以直接从终端访问可用于申请的信息？gnome-shell 是否将回溯日志保存在某处？

我知道 /var/log 中有一个用于 apport 的日志文件，但该日志文件没有提供几乎相同级别的详细信息。
