Before upgrading to 12.04, I was running 11.10. I had a Compiz setting enabled via Ubuntu Tweak. That setting was 'Enable Transparent Menus'. This option allowed all 'right click menus' to be partially transparent, a feature I have grown fond of.

After upgrading to 12.04, I am unable to locate this option. I have installed all of the same packages that were on 11.10, so packages aren't the problem.

I would like to know, where can I enable this? And was this feature removed?



There is a way to do this using the CompizConfig Settings Manager (CCSM), although it is a bit more complicated.


You can very easily break your desktop using CCSM. Follow these instructions and any other answers recommending CCSM at your own risk. If you run into problems, see this question for instructions on how to restore Unity to working condition.

You can install CCSM by looking for it in the Ubuntu Software Center or by entering in a terminal:

sudo apt-get install compizconfig-settings-manager

Once installed, start it up and go into the options for the Opacity, Brightness and Saturation plugin. Click the checkbox to the left of it to enable the plugin first, then add a new rule under the Window specific settings section of the Opacity tab. The "Windows" textbox should contain:


...and the "Window values" slider should be set to 90 (recommended). This value can be tweaked to your taste.

  • +1 for the warning, CCSM is very powerful, but very easy to break – Radu Maris Feb 19 '13 at 8:48
