how to remove tooltip message feature from all of Ubuntu 12.04 desktop and user applications?

Tooltips annoy me too! Here's what I did to get rid of them.

  1. Install Compizconfig Settings Manager

  2. Enable the Opacity, Brightness, and Saturation plugin

  3. Click the New button and add a Tooltip rule as follows:

  • Optional: for awesome slightly transparent right click, drop-down, and app-indicators, make a rule like I have (just above my Tooltip rule), and specify the opacity as 90.
