How to add custom icon for specific application in a unity ubuntu 12.04

I installed a new icon theme for ubuntu 12.04 using "My Unity" i found a very beautiful theme named Breathe, the only problem is it doesn't show an icon for one of my favorite applications (PulseAudio Equalizer) and its icon in unity  shows as a folder icon . (which very annoying)
Here is how to add a custom icon for a specific application in ubuntu 12.04 Unity (hopefully works for all previous unity verions)

First: Find an icon

Fir we need to find an icon for your icon-less application, you can do one of the following:


  1. Steal from another icon theme set
    the location of icon images for icon themes are like this : (Humanity is the name of the icon theme set) :
                                 /usr/share/icons/Humanity/apps/32
  2. Search in google images or in flicker
  3. Take a screenshot of the application (my favorite)
  • Run the application
  • Make sure it is the active window
  • Press alt+print , you will have something like this:


Second: Set the icon


1- Open a root nautilus
sudo nautilus
2- Go to
/usr/share/applications
3- find your application's name in my case (PulseAudio Equalizer), right click and click on properties

4- click on the current icon
5- change it to the image that you found in Step 1 .


now you will see your custom icon for the application that was missing icon file for your icon theme.
