screen rotation - kde display problems

[Fred Schaer]

Funny : after I just reinstalled the kubuntu nvidia drivers and went
back to KDE, the screen display was both rotated and OK...
Doing then a "xrandr -o normal" reverted back the screen as expected,
but then "xrandr -o left" had the same behaviour as below : looks like
some bug...
