-<h2>Problems with JACK configuration<h2>
-
-<p>
- 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.
-</p>
-
-<h5>Symptoms</h5>
-
-<p>
- A message like "Cannot lock down memory" in the output from JACK as
- it starts up. This output may be "hidden" in the Messages window of
- QJackctrl (aka JACK Control), so you should check there.
