In this tutorial, we give the solution to the problem of not being able to change the mouse theme in Ubuntu, and the cause of this problem because Ubuntu distribution uses Compiz.
You may notice that when your choose a mouse theme different theme from the default one which is DMZ-White, through you used tweak-tool or other tools, it will not change, except in a few applications, such as Firefox, and others ... As in the other parts of the system, it will remains on the default theme.
To solve this problem, follow these instructions :
1 Open the terminal Ctrl + Alt + T and paste the following command :
sudo gedit /usr/share/icons/default/index.theme
2. will open a window containing the text of the following codes, or similar :
[Icon Theme]
Inherits=DMZ-White
3, note, the red color, which must be changed to the name of the desired Theme mouse :
Suppose we want black mouse Theme, you must first open tweak-tool application in order to know the name of the theme that we want a DMZ-Black, then we write in the text file as it is written entirely in the tweak-tool, taking into account the large and small letters.
Thus, for the rest of themes, for example, I want the red mouse, looking for its name in the tweak-tool and then type it in the script editor.
4. log out of the system, which is an important step to activate the new mouse theme.
5. Enjoy it.
