I just received a laptop from a friend to fix up. I cleared the hard drive and put Ubuntu on it. This was just yesterday, so it's a fresh install. I'm trying to run PureData, but I'm having issues with it. When I try to start it, it says

Code:
JACK: unable to connect to JACK server
JACK: server returned status 17
I downloaded qjackctl, and upon pressing the start button I get this

Code:
13:08:50.488 JACK is starting...13:08:50.490 /usr/bin/jackd -dalsa -r44100 -p1024 -n3 -D -Chw:0 -Phw:0

Is there a package missing that I can install or is it something more in depth, and what would I have to do? Any help is appreciated, thanks.
I'm running vanilla Ubuntu 13.04.
