Introduction
Even if using an Xserver in an embedded context is most of the times not a necessity, it could be interesting in some "PDA like" applications, where existing applications reuse is needed. Even if recent embedded systems are capable of running a full Xorg server, in low RAM embedded systems we prefer to use the reduced version TinyX/Xfbdev, which is an upper layer of the Linux Framebuffer.
