-  To function as intended, JACK needs to run with access to two
-  operating system facilities called "realtime scheduling" and "memory
-  locking". This means that you, the user who starts JACK, must be
-  allowed access to these facilities. By default, Ubuntu does create a
-  user group that has this permission but ... it does not put new
-  users into this group by default. Consequently, you will not have
-  permission to run JACK in the way you should.

-  A message like "Cannot lock down memory" in the output from JACK as
