I just solved my issue by doing the following steps: ''' $ sudo apt-get purge unity* $ sudo apt-get update $ sudo apt-get install trisquel $ sudo apt-get install mate-dock-applet $ sudo apt-get install mate-desktop-environment-extra '''
The icon theme seems a bit wonky still but this is MUCH better. No need to type "marco" in the terminal in order to get the window buttons to appear.
