How to make ambiance title bar corners squared?

Is there a way to make the corners squared in ambiance or another theme for ubuntu 14.04?

I prefer the look and feel of squared corners.

Solution 1:

Edit unity.css;

1. Open a terminal with Ctrl+Alt+t;

2. Type in the terminal;
   cd /usr/share/themes/Ambiance/gtk-3.0/apps/

3. Now type;
   sudo -i gedit unity.css

4. In gedit (text editor) press Ctrl+f & in the search field that appears type;
   border-radius

5. You should see the search phrase highlighted, our interest is in the proceeding text;
   : 6px 6px 0 0;

6. Modify this text so that the line reads;
   border-radius: 0px 0px 0 0;

   I recommend keeping the px indicators in this line for easy future reference

7. Save and Exit the document.

8. Logout& back in, or change the theme & back again, enjoy!

This method should work with other themes as well, replacing Ambiance in the directory above with the appropriate theme package name;

/usr/share/themes/*theme-name*/gtk-3.0/apps/

Then modifying the corresponding unity.css file as before.

Keep in mind that for some themes there may be another border-radius entry in a separate css class within the same unity.css document that has to do with the window when it is not in focus.

This class will have the name;

UnityDecoration.top:backdrop

the border-radius value here will also need to be changed in order for square corners to work for windows currently unfocused.
