![]() The functionality of the composite manager can be either built into the window manager or be a separate program. Thus, increasing the quality of rendering and significantly reducing the load on the central processor. One of the most important (but optional) functions of the composite window manager is to use the capabilities of the video card to draw the window, usually through Opengl. In this case, the window manager is composite. ![]() Some window managers, in addition to controlling the window, can draw shadows on its edges, add various animations, smoothness, translucency, and so on. In this case, the load for rendering falls on the central processor (the so-called software rendering). In the simplest case, the window manager simply manages the windows and how the input equipment interacts with them, and does nothing else with them. In this case, the window manager works on top of the existing window system. Namely: carries out the positioning of windows on the screen, is responsible for changing their size, focusing and so on. Window manager is the program that manages the application windows on the system. I hope it will be interesting to everyone. I will consider in detail the functions of the window manager, functionality, write about the so-called composite window managers, and so on. But now I finally found the time, and today we will talk about several window managers in popular graphical environments for Linux. Unfortunately, life (and not only) circumstances did not allow this to be done on time. Greetings! Digging through the drafts, I found an old draft for an article that I was going to write a few months ago. Window manager without desktop environment
