Also, if you need any kind of low-latency audio recording / synthesizing 
/ mixing / etc, you definitely need jackd. JACK is to Linux what ASIO is 
to Window$, but on steroids. If you do work with audio, I recommend 
having your kernel patched with the low-latency things and jack 
installed. It works great.
