How to change Menu Opacity

Question

I know how to change the Opacity of the task bar in Unity on Ubuntu 12.10 VIA Compiz. My question is, is there a way I can change the Opacity of the Menus? See, in the image below, it shows the App Bar that it almost transparent. But, on the Calendar, it is mostly black. I would like to make it match the App Menu and all other menus.

You can set the opacity from Compiz Config Settings Manager (install it by sudo apt-get install ccsm). Open CCSM and go to Accessibility page, Then check the opacity brightness and saturation option if not already checked. Then click the same button to go view its options.
In there you'll find the tab Opacity, in this tab clikc on the New button in bottom and enter the values:

Window: DropdownMenu
Window Rules: 75  

Window: popupmenu
Window Rules: 75  

Window: Menu
Window Rules: 75

and back.

Compiz might crash when you check the button but dont worry about that. Just log out then in again and unity will be fixed.
