I searched and not able to find a way to do this.
I find this very annoying. After installing 12.04, I keep getting these tooltip messages from all the applications I use. I want to remove this feature.
For example, now when I move the mouse to launcher near an icon, the toolip message (black background and white font) comes up. I do not want this to show.
I am using the default desktop after installing 12.04 (I think this is called unity).
Here is an answer that shows how to edit a configuration file to change the message itself. But I really want to disable this feature from all applications. Do I have to go edit configurations files to do this?
Here is a screen shot from my desktop showing a tooltip when using firefox. Such tooltips show up in every application I open !
You can see how annoying they are and they get in the way.
I found a way to disable tooltip in firefox, using
and then search for the word tip and make it false.
I hope that I do not have to do this for each application that I use now. It seems every application I use have tooltips enabled on Ubuntu (such as gedit, Libre office software, thunderbird, etc...). On windows, I did not have this problem with these applications. I noticed these tooltips on these applications only on 12.04, that is why I thought it is a configuration feature on 12.04.
I thought there might be a global option to disable tooltips for all applications. May be there is not.
But the point remains, I'd really like to turn off these tooltips for the desktop itself. Like on the launcher and other places on the desktop.
