Linux: runs X sessions within X sessions

Article Title: linux: run X sessions within X sessions. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source.
XFree86 is the basis of the graphic interface of the Linux operating system. Although she seems outdated in many aspects, it is still quite powerful.

One of the advantages of using Linux is that you can use a program named Xnest to run another X session in one session window. Like its name, the Xnest program allows you to run another full-screen X session without closing the current session window.

To nest an X session, open an xterm or a similar control platform in X and run the following command:

$ Xnest: 1-ac &

This command line uses the session window identifier: 1 to start another X session. (By default, session: 0 is used to start X .) This command opens a new window named Xnest, that is, a blank page or a color background page is displayed.

Now, you can start a Window manager such as Window Maker in the new session Window by executing the following command.

$ DISPLAY =: 1 wmaker &

In the new nested session window, you can perform all operations in the regular X session window. When sending a program to the window outside the nested session window, you need to set the DISPLAY environment parameter to start the nested internal session window. You can also process the program in the background so that the program does not run in the session window.
