I upgraded my Dell Inspiron 6500 from Kubuntu 12.10 to 13.04.
Then things "went south".
The worst remaining problem is that the desktop display
breaks after kdm login: the login itself works fine but then
the screen turns _completely black_ during desktop setup.
X and all related processes appear to keep running: the process
table contains them and I hear the sounds the Plasma desktop
makes as it starts running. But I cannot see any of it because
it is all black.

Any idea how to fix this or where to look for clues as to what
is malfunctioning?
