What is the difference between xorg server and xorg x11

X11 is the Unix and Linux graphics drivers. Wayland is a protocol for a compositor to talk to its clients as well as a C library implementation of that protocol.

The compositor can be a standalone display server running on Linux kernel modesetting and evdev input devices, an X application, or a wayland client itself.

What is display server in Linux? A display server is a program which is responsible for the input and output coordination of its clients, to and from the rest of the operating system , and among the hardware and the operating system. Basically, thanks to a display server, you can use your computer graphically GUI. Wayland is a communication protocol that specifies the communication between a display server and its clients.

Please share to your friends:. A client cannot assume that another client can open the same files or even communicate directly.

Thus, passing indirect references to data such as file names, host names and port numbers, and so on is permitted only if both clients specifically agree. So far I thought that "server" was a figure of speech, now I am doubting: is X server a server as in a "web server"? If so, is there anything else in this X11 bundle? X also needs mouse or keyboard or any other kind of input: is this part of X Server's functions too? Is X Window Manager strictly looking after the display only?

Finally, the quote here above also mentions client communicating or not with each other: this reminded me of D-Bus, which I've used a bit for learning purposes. With D-Bus you can also trigger window events. It's a shame this information remains somehow obscure, it makes it harder to learn, but hopefully you can bring some light on this : Thanks.

X is a server and can be compared to a "web server" in that it is a process that listens for incoming connections that speak a particular protocol the X protocol and it issues answers. The connections come from X clients, which may be on the local host or on a remote host accessed over a network. X11 is a "major version" of the X protocol, which has evolved since inception.

X11 is the most recent protocol and the most common. Xorg is an implementation of an X server, X libraries and a collection of clients, all talking X A "window manager" is an X client which manages windows. X requires input and it has a shared responsibility to manage that with the Kernel. Historically, X did a lot of hardware management itself. In modern times, on the Linux platform, X is gradually becoming "smaller" and delegating this responsibility to the Linux kernel.

The advantages of this are: smaller X codebase; fewer "crossed-wires" with the kernel and X both trying to manage the same stuff. There are many, many ways for processes to communicate with each other. I believe X clients can interact by way of the X protocol for example, traditional X window managers need to know when other clients draw windows, in order to decorate them; pagers need to know when a window's size or position changes, in order to reflect that in the pager.

D-Bus is a modern inter-process communication IPC technology developed to address the shortcomings of other methods. It is not X specific. So how to create a common GUI?

Here comes the widget toolkits. They are popular in Wayland and X11 windowing systems. I draw a rough conceptual illustration. The 3 parts above the OS are very customizable.

That's why so much flexibility confusion arise. Xorg and the earlier Xfree, and earlier X10 is a server for a protocol more completely called the X Window System; it allows applications to draw on "the screen".

There are several display servers available. What is X? Here is a list of major windowing systems for both Linux and Windows systems.
