Hi,
  Judging by the behavior you're observing, the system hang indicates
either a bad kernel, or a bad video driver. Since your email doesn't
indicate what video card or driver you're using, it's hard for me to
judge specifically. Those are the two most likely candidates leading
to your problem. Since the system hang occurs when you change the
graphical representation, I wonder if it might be a problem with the
video card or video driver. If you tell me more about your system,
I may have further suggestions.
