Since sending the questions I have got event driven keyboard and mouse
input to work. I still don't know why
the example that does non-event driven keyboard access doesn't appear to
work. (Still investigating.)

What is the linuxinput driver? This is not so important now that the
mouse and keyboard are working, but what do
I need to do to use the linuxinput driver?

Yes the dfbinfo example showed this for the mouse and kbd:
Input (00) Keyboard (primary keyboard)
Type: KEYBOARD
Caps: KEYS
Input (01) IMPS/2 Mouse (primary mouse)
Type: MOUSE
Caps: AXES BUTTONS
Max. Axis: 2
Max. Button: 2
And the df_input example worked. The only small question mark is that I
noticed that the program can get well
behind the mouse if there is a lot of movement, as if the drawing of the
mouse position crosslines could not keep
up with the mouse movement events, which kind of surprised me.

Before I was running the directfb programs I had been running an
X-server, but stopped it. After I stop the X-server, then
from then on the X-server's mouse cursor shows up on the screen when a
DirectFB program is run - it always shows
up in the same position and doesn't move with the mouse. I tried a few
things to clear it but couldn't find anything that
worked. DirectFB's mouse cursor is displayed in some of the test
examples, and looks, as you say, like a water droplet.
