Display Server Protocol
In computing, a windowing system (or window system) is software that manages separately different parts of Electronic visual display, display screens. It is a type of graphical user interface (GUI) which implements the WIMP (computing), WIMP (Window (computing), windows, Icon (computing), icons, Menu (computing), menus, Pointer (user interface), pointer) paradigm for a User Interface Toolkit, user interface. Each currently running Application software, application is assigned a usually resizable and usually rectangular surface of the display to present its GUI to the user; these windows may overlap each other, as opposed to a tiling interface where they are not allowed to overlap. Usually a Window (computing)#window decoration, window decoration is drawn around each window. The programming of both the window decoration and of available Graphical widget, widgets inside of the window, which are Computer graphics, graphical elements for direct user interaction, such as sliders, but ...

Evdev
evdev (short for 'event device') is a generic input event interface in the Linux kernel and FreeBSD. It generalizes raw input events from device drivers and makes them available through character devices in the /dev/input/ directory. The user-space library for the kernel component evdev is called libevdev. Libevdev abstracts the evdev ioctls through type-safe interfaces and provides functions to change the appearance of the device. Libevdev shares similarities with the read system call. It sits below the process that handles input events, in between the kernel and that process. : kernel → libevdev → xf86-input-evdev → X server → X client For Weston/Wayland, the stack would look like this: : kernel → libevdev → libinput → Wayland compositor → Wayland client Since version 1.16 the xorg-xserver obtained support for libinput: : kernel → libevdev → libinput → xf86-input-libinput → X server → X client evdev is primarily used by display server In c ...
