I have almost the same setup (ubuntu instead of kubuntu) and similar
problems.

I connected two TFTs (Dell 20", 1600x1200) to the docking station and
booted up the notebook. GRUB and the splash screen show up correctly on
the primary display which is connected to the DVI port of the docking
station. The graphical login appears on the secondary display which is
connected to the VGA port of the docking station, everything is OK so
far.

After logging in I used the NVidia settings panel in order to enable the
second screen (the one connected to the DVI port) using "twinview" and
configure it to be left of the secondary display. I choose "apply" and I
get garbled output on both displays. Sometimes I can restart the X
server now, but quite often it simply switches to a completely black
screen on which I only have the mouse cursor. At this point, keyboard
input is ignored completely, so I have to turn the power off in order to
restart the computer.

An interesting detail: If I just activate the primary display but don't
configure it to be on left (it's on the right of the secondary display
per default), everything works in most cases even though I get the
problem as described above _sometimes_. I really couldn't find any way
to reproduce the problem, it's unnervingly non-deterministic. One time I
got the interesting effect that everything looked fine (except the
displays being swapped because I didn't move the primary display to the
left) but mouse klicks and keyboard events were ignored completely. I
had a mouse cursor I could move around, but clicking didn't have any
effect.
