ive had decent luck by renicing the X server to a lower priority (higher number) and doing
the opposite to jackd. depending on how your X is started (gdm, xdm, startx) the way to
nice it on launch may differ, but give it a shot..
im not sure 'top' can be trusted. for ex running ices doing a realtime ogg encode
takes 5-6% CPU , without X running, and as soon as X is launched, that number doubles,
according to top..
