Mike,

Thanks for the reply. Before trying to add xorg config files
I would like to understand what is going on.

Why does the trackpoint work but not the touchpad though both
are recognized at startup and seem to be "initialized" judging
by dmesg, etc. (F15).

I would expect the touchpad to also work in a primitive way.
