Although the Unity launcher is very useful for general use computing it can get in the way when playing windows games in Wine. Here is a trick I use to disable the Unity launcher in wine

unity-wine.sh

#!/bin/sh 
 
dconf write /org/compiz/profiles/unity/plugins/unityshell/show-launcher '""'
$1
dconf write /org/compiz/profiles/unity/plugins/unityshell/show-launcher '"<Super>"'
