my windows do not resize when I drag them on top or on side of my screen

Solution 1:

You'll need to make sure that settings is setup in Compiz. Here's how to do it.

If you don't Have Compiz Config Settings Manager installed you can install it by running the following command in a terminal:

 sudo apt-get install compizconfig-settings-manager 

You can then launch it by running the following command in the terminal

ccsm

You'll then want to find the 'Grid' Settings Option under Window Management. Then if you click on the 'Edges' tab you'll be able to change the drop-down menus in "Resize Actions" to whatever you want to setup the edge-binding resize actions.
