Framebuffer Framebuffer

Framebuffer - Definition and Overview

The framebuffer is a part of RAM in a computer allocated to hold the graphics information for one frame or picture. This information typically consists of color values for every pixel (point that can be displayed) on the screen. A framebuffer is either:

  • Off-screen, meaning that writes to the framebuffer don't appear on the visible screen
  • On-screen, meaning that the framebuffer is directly coupled to the visible display

The linux framebuffer device (fbdev) driver was added to Linux to support the Macintosh display, which does not have a text mode. It was ported to x86 and is used to display a logo (often Tux) above a screen of text.
