I started using Ubuntu 12.10 today, and put in my social networking details in Online Accounts under System Settings. I like being able to chat with my Facebook friends in Empathy, but I don't necessarily want my tweets to go to Facebook. I want to remove Facebook from Gwibber, but not Empathy. How do I do this? There is nothing in Gwibber preferences and I can't see how to do it in Online Accounts. The reason I want to remove it is that it isn't clear enough which accounts are posted to and I don't necessarily want the feeds mixing together.
As an option, you can delete the package
I haven't tried this yet, but I recently asked the same question on G+, and this is the answer I received:
'sudo sed -i 's/NoDisplay=true/NoDisplay=false/g' /etc/xdg/autostart/*.desktop
Go into startup applications and uncheck gwibber'
Hope that helps.
