This is great, Kari!  Not only should that "sudo password" 
command be added to the installation instructions on the 
Trinity webpage, but a link to that howtogeek web page 
should be included also.  That page is a very nice visual aid 
for installation and use of Trinity on Ubuntu.

Trinity on Oneiric is probably the most important installation
because:

1 Ubuntu is the most popular Linux distro.

2 Most people probably use the latest version -- Oneiric Ocelot.
  
3 Ubuntu needs TDE more than any other distro, since its 
  default DE is so oversimplified.
