Thread: jack Server not working

i enjoy making music ubuntu amsynth , hydrogen...i connect midi keyboard thru kaconnect because when try start jackd server never works.

sucks cause connect effects sounds make rakarrack example , output ardour.
both programms tell me jack server isn't running.
if start qjacktctl , hit start gives me following output:

code:
