The driver modules usually get installed when you do "make DESTDIR=/foo/bar
install".
Without an accelerator, using the frame buffer device, you don't need a graphics
driver module. But in most cases you'd like to have input at least, though you
could
have your own way of receiving input on a device, if you just run one
application
which is written for it.
If you copied over the libraries manually, you also need to copy the following
directory:
/usr/lib/directfb-1.1-0

The rest seems fine. You can try the DirectFB-examples next. Nice to see are the
test programs df_dok (benchmarking) and df_andi (sprite demo).
For a user interface you should have a look at LiTE, Disko or GTK+, while the
first
one has the least overhead, but also the least features at the moment. It's
merely
an engine for writing your own widgets on top of DirectFB, but there is a
growing
number of base or example widgets incorporated.

It's the base UI library behind the "lightweight DirectFB windowing system
[that] sets a new
standard of responsiveness and simplicity for mobile Linux" as said by David
Beers after evaluating
the Palm Foleo.
