X 服务器在昨晚更新后崩溃

我昨天进行了升级，其中有一些 plymouth 软件包（不确定这是否与这些软件包有关，但我认为那些是唯一的“图形”软件包。）今天早上，当我将我的 Dell XPS 13 (9370) 连接到我的 TB 16 扩展坞并启动时，X 一直崩溃。如果我拔下扩展坞，X 可以正常启动，并且在登录屏幕出现后我就可以连接扩展坞。以下是 X 崩溃日志：

我目前有一个解决方法，但如果有人能提示如何解决这个问题，我将不胜感激。但也许我需要一个或两个改进版本的包？

问候，

如下面引用的堆栈跟踪所示，库中有一个空指针取消引用libpciaccess.so.0：

[     6.656] (EE) 3: /usr/lib/x86_64-linux-gnu/libpciaccess.so.0 (pci_device_next+0x118) [0x7fcd1a259a38]
...
[     6.656] (EE) Segmentation fault at address 0x0

使用apt-file search libpciaccess.so.0，可以位于包中的库libpciaccess0，在 Ubuntu 16.04 中，它返回以下信息aptitude show libpciaccess0：

Package: libpciaccess0
State: installed
Automatically installed: yes
Multi-Arch: same
Version: 0.13.4-1
Priority: optional
Section: libs
Maintainer: Ubuntu Developers <[email protected]>
Architecture: amd64
Uncompressed Size: 63.5 k
Depends: libc6 (>= 2.7), zlib1g (>= 1:1.1.4)
Suggests: pciutils
Description: Generic PCI access library for X
 Provides functionality for X to access the PCI bus and devices in a
 platform-independent way.

然而，在 Ubuntu 20.04 中，该库较新，但具有相同的依赖性，如下所示：

Package: libpciaccess0
Version: 0.16-0ubuntu1
State: installed
Automatically installed: yes
Multi-Arch: same
Priority: optional
Section: libs
Maintainer: Ubuntu Developers <[email protected]>
Architecture: amd64
Uncompressed Size: 62.5 k
Depends: libc6 (>= 2.7), zlib1g (>= 1:1.1.4)
Suggests: pciutils
Breaks: libpciaccess0:i386 (!= 0.16-0ubuntu1)
Replaces: libpciaccess0:i386 (< 0.16-0ubuntu1)
Description: Generic PCI access library for X
 Provides functionality for X to access the PCI bus and devices in a
 platform-independent way.

因此，解决问题的方法是简单地安装 Ubuntu 20.04 提供的软件包，如下所示，即可解决问题：

  • 在 Ubuntu 20.04 中，下载软件包：aptitude download libpciaccess.so.0。
  • 将获取的文件复制libpciaccess0_0.16-0ubuntu1_amd64.deb到Ubuntu 16.04。
  • 在 Ubuntu 16.04 中，安装该包：sudo dpkg -i libpciaccess0_0.16-0ubuntu1_amd64.deb
  • 重新启动 Ubuntu 16.04，问题就解决了。
