It's very tiring to have to keep looking at the default image of the Ubuntu logo in the dash. How do you change this default image into a custom image (btw, in my case I have a 48x48
.png ready to be changed to)?
Just copy your
/usr/share/unity/icons/. In your case(I am assuming that your png file located in /home/flatenken/Downloads/launcher_bfb.png), you must give this command:
sudo mv /home/flatenken/Downloads/launcher_bfb.png /usr/share/unity/icons/
