Oh thanks, I unfortunally allready DID pay attention to him, but will
take it in mind for future.

I just managed to put down the X-Server Error Window with a PS2-Keyboard
instead of one with USB plug. I guess that behaviour roots in the udev
failure.
The error report of the X-Server states dozens of files not found and
objects not loadable, and warnings amount to about hundred.

Now I have installed a parallel edge version that runs fine, but if
anyone dared to explain what went so terribly wrong with the update I
would be grateful still.

Thanks anyway,

Robert
