+<h2>High Level Recommendations for Ubuntu Users</h2>

+  Currently, installing pro audio applications on vanilla Ubuntu requires 
+  some configuration, in order for the user to gain realtime privilege 
+  (read below). 
+  Ubuntu Studio, which is an official flavor of Ubuntu, and thus shares 
+  the repositories with Ubuntu, has this already configured.
+  Another distribution, KXStudio, is largely based on Ubuntu, and also has 
+  these settings preconfigured - also containing many customized and often 
+  more up to date packages.

-<h2>Problems with JACK configuration<h2>
+<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.
-</p>
-
-<h5>How to fix</h5>
-
-<p>
-  Run the command <code>sudo usermod -a -G
-  audio <em>YOUR-LOGIN-NAME</em></code>. Then logout and login again.
