Re: How do I completely remove a program and all it's data in Ubuntu 12.04 ?
Although others are answering the thread title, what would be more useful is to be able to see the program's notification area icon.
This old article still applies to Ubuntu 12.10. You should also contact the developer of the program and ask them for Indicator support, as the notification area will be removed in 13.04.
I try to treat the cause, not the symptom. I avoid the terminal in instructions, unless it's easier or necessary. My instructions will work within the Ubuntu system, instead of breaking or subverting it. Those are the three guarantees to the helpee.
