"pasuspender -- jackd" That would start jackd using $HOME/.jackdrc as the 
commandline. Then qjackctl would not start using it's settings because 
jack is already running. Now that qjackctl has been able to start jackd at 
least once, those settings should have been saved to $HOME/.jackdrc so 
adding the "pasuspender -- jackd" back in would _appear_ to work. 
Pasuspender shouldn't be needed anyway unless you are running with no dbus 
running. Dbus running or not seems to be a personal choice even with no X
