Sticky Edges

Seems that sticky edges cannot be configured under Display settings in 12.10.
Instead go to CCSM -> Unity -> Experimental and uncheck Capture Mouse.

Move window

Working with two monitors is very nice, and there is a nice feature in Compiz to quickly move current window to the other display.

To enable it:

1. Install packages compiz-plugins compiz-config-settings-manager
2. Open ccsm and enable plugin Put
3. Go to the configuration for Put
4. Set a keyboard shortcut for the function Put to next output 
5. (Not always needed) Restart Unity by running setsid unity from a terminal
