Symptom:
During startup of (eg) gnome3 or (ew) unity, the system locks up hard.
'classic' mode on gnome3 works though. (unity still unusable, but I'm not sure it ever could be on this system)
Probably cause:
ION2 chipset - is Intel + nVidia chipset, the nVidia is not supposed to be called unless it is explicitely activated. Am guessing the application is attempting to make calls on non-operational nvidia.
(note: crashes FAR worse if neuveaux driver present, causing data loss)
Primary driver is intel. Secondary (nvidia) operates within a memory window - it's like the 3DfX driver back in the day. Computer and chipset both new.
Purpose of dual chipset is that intel is low-power mode, nvidia kicks in for high-performance apps. (eg: NOT the desktop)

critical bug, makes system unusable.
Probably affects all installations with dual layered graphics chipsets - ION, ION2 (intel+nvidia or intel+ATI). May affect systems with overlay hardware (tv cards, 3dfx if any still around, ...)
