Ubuntu > dragging windows to desktop sides not working

Problem

Basically, dragging windows to sides of the screen isn't readjusting the window size to half the screen.

(I later found out this feature was called "window grid".)

Solution

I'm reposting the solution, because it worked.

In the terminal...

1. compiz --replace & disown
2. (I then needed to logout and log back in, as none of my windows were responding)
3. unity --reset

That should be it, windows now snap to half the screen, when dragged to the sides of the desktop.
