The Linux framebuffer (fbdev) is a graphic hardware-independent abstraction layer to show graphics on a console without relying on system-specific libraries such as svgalib or the heavy overhead of the X Window System. The framebuffer is a part of RAM in a computer allocated to hold the graphics information for one frame or picture. ...
A layer is the following: In abstraction, a layer is an abstract place conceived as having depth. ...
Computer graphics (CG) is the field of visual computing, where one utilizes computers both to generate visual images synthetically and to integrate or alter visual and spatial information sampled from the real world. ...

In computer science, and moreso in computer programming, overhead is generally considered any combination of excess or indirect computation time, memory, bandwidth, or other resources that are required to be utilized or expended to enable a particular goal. ...
In computing, the X Window System (commonly X11 or X) is a windowing system for bitmap displays. ...
It was originally implemented to allow the Linux kernel to emulate a text console on systems such as the Apple Macintosh that do not have a text-mode display, and was later expanded to Linux's originally-supported IBM PC compatible platform, where it became popular largely for the ability to show the Tux logo on boot up. More significantly, it serves as a way of displaying Unicode characters on the Linux console. Under the non-framebuffer, VGA display of the PC, comprehensive Unicode support was impossible, for VGA console fonts were limited to 512 characters. The Linux mascot Tux created by Larry Ewing The Linux kernel is a free Unix-like operating system kernel that was created by Linus Torvalds in 1991 and subsequently improved with the assistance of developers around the world. ...

Nowadays several Linux programs such as MPlayer, and libraries such as SDL or GTK can use the framebuffer immediately, avoiding the overhead of the XFree86 server. This is particularly popular in embedded systems. MPlayer is a free media player with support for more multimedia formats than any other media player. ...
Simple DirectMedia Layer (SDL) is a cross-platform multimedia library that creates an abstraction over various platforms graphics, sound, and input APIs, allowing a developer to write a computer game or other multimedia application once and run it on GNU/Linux, Windows, Mac OS Classic, Mac OS X, BeOS and...

The Linux framebuffer has long suffered from its poor performance, but there is now a library DirectFB which provides a framework for hardware acceleration. DirectFB is a computer library for Linux operating system that provides hardware graphics acceleration, input device handling and abstraction, integrated windowing system with support for translucent windows and multiple display layers on top of the Linux Framebuffer Device. ...
FBUI (FrameBuffer UI) provides in-kernel windowing system (GUI) for the framebuffer subsystem at very low cost: the entire subsystem is about 50 kilobytes in size. It permits multiple programs to share the framebuffer simultaneously; it permits overlapping moveable windows; each program may have multiple windows; and it allows windows on every virtual console. Included with FBUI is libfbui which provides abstractions for windows, events, etc., as well as quite a few sample programs such as load monitor, clock, calculator, scribble pad, image viewer, window managers, and a simple MPEG2 player. FBUI includes an optimized code for the VESA framebuffer driver. fbui (FrameBuffer UI) is an in-kernel graphical user interface for Linux that sits on top of the framebuffer subsystem. ...
