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

            X11R7 Applications  --->
                ...
                [*] xclock
                ...
                [*] xeyes
        ...
        [*] xterm

Launching

  • For example, with a mouse and a keyboard (event0):
# /usr/bin/X -mouse evdev -retro -keybd evdev,,device=/dev/input/event0 &
  • Or with a touchscreen (event0):
# /usr/bin/X -retro -mouse tslib,,device=/dev/input/event0 &

then you will need to launch a window manager (like Matchbox/Blackbox/Fluxbox/Openbox) and some applications....

# xterm &
# xeyes &
