Hi,
important here is now DFB is initialized.
It is possible to run DFB on top of the frame buffer device, or on top
of X11.
If you run DFB on top of the frame buffer device, then X11 is not
allowed to run.
If you want to run enlightenment etcetera, you have to compile these to
run on top of DFB using GTK.
You cannot run X11. You can easily see this by doing ldd on your
required libraries.
If you run DFB on top of X11, than you can specify a window where all
DirectFB applications run inside. I think you want this.
Please note that DFB cannot perform hardware acceleration as long as X11
is running!
By default DFB runs on top of the frame buffer device, you need to
specify "system=X11" to run it on top of X11.

Yes, I have, but at the beginning, DFB will flush the whole screen as
white, then it will render the images in the defined region, how can I
disable the whole screen flush at the beginning? Thanks

Why not create a window correctly positionned/sized to fit your
needs ?
