Marking incomplete pending more info. Intel driver has known dual-screen limitation of 2048 by 2048 pixel space. If your screens (combined) exceed this limit (in either direction) you will get an xorg crash. Log file shows hitting video memory limit before lockup.
Try reducing resolution on both screens to stay within 2048 pixel limitation. KDE4 may choose safe resolutions by default.
