I have also seen the disappearing mouse trick under non-KDE Ubuntu (Breezy). I'm running an ATI video card. I can't recall if I was using the accelerated fglrx video driver or the open source radeon video driver.
Like Rick says, it only happens once in a blue moon. I have not seen this particular problem on my (K)ubuntu nVidia machine at work.
