This may be related to DVMT; Intel's Dynamic Video Memory Technology.
... its supposed to work with Microsoft's proprietary driver to
dynamically allocate video memory resources (up to 128 M) for 2D - 3D
performance and then return the memory resource to the OS when finished.
My machine defaults to 8M preallocated, 0M fixed, and 120M DVMT...

I changed the default settings to 8M preallocated 120M fixed and 0M
DVMT... and the freeze is gone...  even with compiz.real running w/
screensaver.    I left the silly thing running all night... no problems.

Perhaps the i915 driver isn't working well with DVMT ;  Intel integrated
graphics chipset 915   945  ?

m harris
