gpu crash dump

Ubuntu 15.10, Intel Atom N280, Intel 945GME integrated graphics.

On occasion, the screen will appear to stop responding, although the cursor
will still move.  The screen then goes black, before coming back as a corrupted
mess.  The corruption appears as incoherent horizontal lines, and the screen
appears to be comprised of multiple small tiles of the same image, as movement
of the cursor or scrolling of the open application causes identical change in
each tile.  Pressing the Super (Windows) key causes the Ubuntu 'Start' (I
forget what it's actually called) menu to display normally, and the corruption
and tiling to resolve itself.

Some corruption does remain in the applications display, although scrolling the
content or otherwise modifying the window geometry does cause this to
disappear.

I have observed this happening in Midori, Firefox, Gnome Terminal, Geany, and
likely other applications I cannot remember right now.
