sudo gainroot cd /usr/share/applications leafpad defaults.list The above will create & open up an empty file called defaults.list in the /usr/share/applications folder. Copy & paste the following into it: text/plain=hildon-osso_notes.desktop & then save it. Now when you open a text file it will open in 'notes' again; you don't need to restart anything as its effect is immediate. [based on info I found here]
