I have the cursor theme that I want, but how do I install it? Do I have to move it to a folder, then go to Ubuntu Tweak or MyUnity for example and choose it from there?
just copy your downloaded files to your .icons (ctrl+h to see it) folder located in your home directory. Create a folder then paste the index.theme, cursor.theme files and the folder of the cursors inside it. Use Ubuntu Tweak to choose it.
