Do you miss an "show desktop" icon on the Unity Launcher?

Show desktop Unity

Run the following commands in a terminal:
sudo apt-get install wmctrl
cd
wget http://webupd8.googlecode.com/files/showdesktop.tar.gz
tar -xvf showdesktop.tar.gz && rm showdesktop.tar.gz
sudo mv showdesktop /usr/local/bin/

Then navigate to your home folder and drag and drop the "showdesktop.desktop file on your Unity launcher. Or use SUPER + D keyboard shortcut to show/hide the desktop.

홈폴더에서  "showdesktop.desktop" 파일을 클릭해서 유니티로 가져가시면 됩니다.
