我试图修复在 Sony Vaio VGN-NS135E 上安装 Ubuntu 12.04 64 位时出现的双显示器问题。
我运行了以下命令（从以下位置下载了 deb -https://launchpad.net/ubuntu/+source/xorg/1:7.6+12ubuntu1/+build/3309759)：
sudo dpkg -i xorg_7.6+12ubuntu1_amd64.deb
因为我很沮丧，有人告诉我恢复 xorg 可能会有帮助。我最终以某种方式解决了我遇到的显示器问题，但现在我遇到了安装失败的问题。（顺便说一句，一旦我在启动前插入显示器并重新启动，显示器现在就可以正常工作了。）
我现在的错误是，我有一个部分配置的 xorg 包，似乎无法删除它。我也无法打开软件中心，因为它不想修复，修复失败的原因与下一个代码块相同。以下是 sudo apt-get autoremove 的输出：
sudo apt-get autoremove

You might want to run 'apt-get -f install' to correct these.
The following packages have unmet dependencies:
xorg : Depends: xserver-xorg (>= 1:7.6+12ubuntu1)
E: Unmet dependencies. Try using -f.
我已尝试帖子上的所有命令：如何强制配置部分安装的软件包？

在虚拟控制台 (ctrl+alt+F1) 上尝试以下命令，
sudo service lightdm stop
sudo dpkg --purge --force-all --force-remove-reinstreq xorg
sudo apt-get install xorg
在 tty 中执行上述命令是安全的。
reinst-required
A package marked reinst-required is broken and requires rein‐
stallation. These packages cannot be removed, unless forced with
option --force-remove-reinstreq
purge
The package is selected to be purged (i.e. we want to remove
everything from system directories, even configuration files).
force-all
Set all force options
