-<p>
-  Unfortunately, Ubuntu has repeatedly caused major headaches for
-  people who want to use Ardour. These problems have arisen from a
-  combination of two basic issues:
-
-  <ul>
-    <li>Badly built packages of Ardour</li>
-    <li>Poor system configuration related to JACK, which Ardour (and
-    most other pro-audio tools on Linux) uses for audio and MIDI I/O.

-<p>
-  If you not yet committed to using Ubuntu for pro-audio or music
-  creation work, you should probably consider using a different
-  distribution that has a demonstrated history of not making life for
-  users like you more complex than it needs to be. In particular you
-  might want to consider a distribution such
-  as <a href="http://www.bandshed.net/AVLinux.html">AVLinux</a>
-  or <a href="http://www.dickmacinnis.com/dreamstudio/">Dreamstudio</a>
-  that is specifically focused on media creation work.
+  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.
+  Other distributions, such as KXStudio, and Dreamstudio are largely based 
+  on Ubuntu, and like Ubuntu Studio, has these settings preconfigured, while
+  also containing customized versions of Ubuntu packages, which often are
+  more up to date.

-<dt>What is the problem?</dt>
-<dd>
-<p>
-  It is not possible to know whether the current package of Ardour
-  released by Ubuntu has been correctly built or not. Ubuntu has a
-  history of making packaging errors that lead to crashes, missing
-  functionality and odd behaviour that is not present in the
-  ready-to-run version of the program that you can get from a
-  href="http://ardour.org/download">ardour.org</a> (or in the packages
-  released by other distributions)
-</p>
-<dt>Symptoms</dt>
-<dd>
-<p>
-  Ardour starts up and basically runs, but you encounter subtle
-  problems (for example, with plugin GUIs or with export, or with the
-  use of certain specific plugins), or are missing functionality, or
-  run into crashes.
-</p>
-</dd>
-<dt>How to Fix</dt>
-<dd>
-<p>
-  Download the ready-to-run version
-  from <a href="http://ardour.org/download">ardour.org</a>. Ardour's
-  lead developer (and many of the most active members of our user
-  community) will not provide support for, and will not investigate
-  bugs reported for, Ubuntu's own packages of Ardour. The ardour.org
-  packages install along side your distribution versions, and do not
-  interfere or interact in anyway other than sharing your own personal
-  Ardour settings and configuration choices.

+<h2>Installing Ardour</h2>
+  There may be unintended differences, and even bugs in Ubuntu native 
+  packages, as a result of a different building method. For this reason,
+  Ardour developers highly recommend you to install the official
+  ready-to-run version of the program that you can get from <a
+  href="http://ardour.org/download">ardour.org</a>, as Ubuntu native
+  packages are not supported in official Ardour forums or other
+  support channels.
