If you're using Intel graphics, try adding this to your video device section:
Option "MigrationHeuristic" "greedy"

Then it'll use the same settings as 8.10 uses.  It actually keeps my graphics 
(i965) from locking (the mouse-moves-but-nothing-else-works thing).

There's also, experimentally, DRI2 available.  It makes very pretty smooth 
animations like on a better-quality graphics card.  It's also, like I said, 
experimental.  It makes X crash & restart when I suspend if I have compositing 
enabled at the time.  Which means I just disable compositing before I suspend.  
The effects vary by specific graphic card.  See 
https://wiki.ubuntu.com/X/UxaTesting for results by card and instructions.
