NeoDesktop集成Linux图形化界面文档

前言​

目前 Neo 集成了一个完整的 termux，与 termux app 完全独立，软件源是根据 termux-package 编译的，编译一次大概需要一天的时间，目前编译了 2800+ 的包

由于与 termux 完全独立，所以 termux-x11 也需要配合 Neo 的包名，需要重新编译一个版本

Termux X11 Neo 下载

创建 Linux 容器​

目前我已经编写好了一键创建的命令 打开 Neo 自带终端，执行

install_debian

然后就是漫长的等待，终端一直在输出问题就不大，软件源我已经换成了清华源，不用梯子

我后面会尝试做一个整合包

运行 Linux 容器​

直接启动会有个问题，termux-x11-neo 会被打开，Neo 会被切换到后台，而 x11 和 Neo 是需要通信的，但是小米这类，就会直接掐断他们之间的连接

所以你要么将 Neo 悬浮窗出来

要么就先在 Neo 中打开 termux-x11-neo

打开后是这样的

image

这个时候我们再打开 Neo 的终端

./start_debian_x11.sh

如图

运行其他的发行版​
