How to develop a DirectFB app without leaving X.11 environment

Question

I\'m trying to develop a GUI application for an embedded platform, without any windowing whatsoever and I\'m doing that with DirectFB, and it suits my needs very fine.

Answer 1

DirectFB has a X11 backend.

$ sudo apt-get install libdirectfb-extra  # for Debian and Ubuntu, anyhow
$ cat ~/.directfbrc
system=x11
force-windowed

Also, DirectFB has a SDL backend, and SDL has a X11 backend. Also, SDL has a GGI backend, and GGI has an X backend. That's a bit circuitous, but it should work :)

I tested it with

$ SDL_VIDEODRIVER=directfb ffplay some_movie.avi

and got a nice 640x480 window with media playing and DirectFB handling layering and input, so I'm sure this works.
