As it's always the same hardware, it's a question of getting the software to program the video hardware in a way which gives identical timing to 'doze. The differences between distros is nothing intrinsic - just how each of them decides to program the video timing. The correct course of action is to find out the correct modelines which give a good result. First I'd try to find any Linux which comes up with useable modelines. Or perhaps good ones, as opposed to just usable ones. If that turns a blank, some action with an oscilloscope (I have access to one) might be in order for debugging and investigation. KDE or gnome should not have anything to do with the video timing, which is controlled by the X server. It some cases however it appears that KDE/gnome have control over timing, because they can interface to the X server and e.g. cause a screen resolution change.
