fedup 20 -> 21 -> xinit -> KDE -> No mouse/keyboard input

[Rich Emberson]

So, I am now at the point where xinit (calling startkde)
has the KDE screen appearing, but ...

The pointer-cursor appears but can not be moved by the mouse, and
(after some timeout and the login screen appears) keyboard
entry fails.

What does one do to enable both the mouse and keyboard.

Thanks
Richard
