我想自己编写一些针对笔记本电脑显示器的帮助脚本，并且希望使其通用。
我注意到，在 3 台装有 Ubuntu 22 的不同笔记本电脑上，笔记本电脑显示屏始终标记为xrandr“ eDP-1 ”。
情况总是如此吗？
如果不是 - 影响此生成的显示名称的条件是什么？
我在某处发现 eDP 应该意味着“嵌入式显示端口”，因此我假设如果笔记本电脑没有更多嵌入式显示端口，它将始终标记为eDP-1. 但后来我发现这个问题 - eDP-1-1 到 eDP-1 - 对于 Ubuntu 20 和这个存档https://lists.x.org/archives/xorg/2017-March/058634.html提到“eDP-1 -1”在初始状态 - 这让我有点担心。我也未能找到描述 eDP 含义和规则的文档。
设想：
我尝试使用meldGUI，但完成这些结构需要无穷无尽的时间。
我尝试使用diff --brief --report-identical-files folder1 folder2，但它基本上报告了所有内容，它甚至不包括文件夹，所以我什至不能| grep identical。
我是否使用了错误的工具？还是有一些我没有从中得到的技巧diff --help？还是我做错了什么？
谢谢
我最初对 swap(piness) 的问题是它交换得太频繁了（即使是swappiness=1! ）。
我还认为 0 会关闭 swappiness - 这是一个误解，
即使你设置了 Swap 仍然有效sudo sysctl -w vm.swappiness=0！:-)
（要永久设置，编辑/etc/sysctl.conf和添加/更新vm.swappiness = 0- 对于 GUI 文本编辑器，我推荐一个“linux notepad”“gedit”，然后你可以这样做sudo gedit /etc/sysctl.conf）
只有在交换0时，它才开始表现得更像人们所期望的那样（从大约 98% 的 RAM 满时开始交换），但是我仍然遇到另一个问题 - 当实际上再次释放足够的 RAM 时，交换不会自动返回到 RAM，甚至随着时间的推移。
当然，您可以手动执行sudo swapoff -a; sudo swapon -a每次关闭交换，最终强制交换被清空到 RAM，然后交换再次开始。
然而，这并不方便，原因有两个 a) 交换会暂时关闭 b) 这是手动的额外检查/运行
有没有办法自动以某种方式实现这一点，最好是“本地” ？
因此，当我尝试安装时，wine它没有问题，但是它显然没有安装我要运行的应用程序所需的 wine32。
我已经加了sudo dpkg --add-architecture i386
但是，当我尝试sudo apt install wine32遇到这些错误时：

经过深入研究，似乎有两个问题：
1）一些依赖关系“打破”对方
2) 在 Ubuntu 20.04 中不可用的版本中需要许多依赖项
我可以以某种方式强制 wine32 install 安装所需版本的依赖项吗？
旁注：从 Ubuntu 18.04 升级到 20.04 后，wine 坏了，在 18.04 上，我不知何故使用 add architecture 和 winehq 存储库让它工作得很好......

我在运行 Ubuntu 17（使用 Xfce 会话）的根分区上需要更多空间。
我之前确实有很多未分配的空间。
但是，当我尝试调整根分区的大小 -/dev/sdb2时，我无法添加/删除 MiB ...
这甚至可能吗？
如果是这样，是否可以通过实时系统以某种方式完成，还是我必须使用实时 CD/USB？
实际上只有 Ubuntu 和 Xcfe 会话，LUBUNTU_SYSTEM 只是一个旧标签 :)
