I recently tried to add a secondary monitor to the left of my laptop screen by using xrandr --output VGA --auto --left-of LVDS. this work fine except when I add/removed the secondary monitor, the origin point of the vitural screen changed, but kwin only remember the old coordinate of the windows. So by adding/removing a secondary monitor, all the windows is moved a lot to the left or to the right(out of the screen). I do not know how hard it is to implement, but is it possible to detect the origin of the vitual screen is actually moved and shift the coordinate of the windows accordingly?
