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.
Installing
$ make menuconfig
| Low RAM | > 256 Mbytes RAM |

Launching
| Low RAM | High RAM |
|---|---|
* For example, with a mouse and a keyboard (event0):
# /usr/bin/X -mouse evdev -retro -keybd evdev,,device=/dev/input/event0 &
# /usr/bin/X -retro -mouse tslib,,device=/dev/input/event0 & |
# /usr/bin/Xorg :0.0 vt01 -s 0 -noreset -retro |
then you will need to launch a window manager (like Matchbox/Blackbox/Fluxbox/Openbox) and some applications....
# xterm & # xeyes &
