<para xml:id='p2'>'Tis better to be silent and be thought a
fool, than to speak and remove all doubt.
</para>
</epigraph>

<para xml:id='p1'>Although already well established in the twentieth
century,
<link xlink:href="/2006/03/24/dita2006">DITA 2006</link> was
the first time I'd ever used “dual screen” mode to give a
presentation. In dual screen mode, you get two connected but
independent desktops. With a laptop, that means you can project one
desktop while viewing another on your LCD panel. I can't imagine
giving presentations any other way again!
</para>

<para xml:id='p3'>It took
<link xlink:href="http://mailman.linux-thinkpad.org/pipermail/linux-thinkpad/2006-March/032721.html">a little fiddling</link>
to get dual screen mode working on my laptop, and it's not very useful
“day to day” because I like to be able to take my laptop out of my
office and continue working without worrying about “losing windows” on
what would be the invisible second screen<footnote><para xml:id='p4'>Mac and
Windows users may be able to gloat a little bit here about more
dynamic configuration. I can toggle dual screen mode without rebooting,
but not without logging out and back in.</para></footnote>.</para>

<para xml:id='p5'>But in a presentation setting, being able to have an active
desktop with notes and other props while projecting something else was
really handy. I'll probably wind up working on some improvements to
the Slides document type to make generation of the “real” and “notes”
views easier. And it'd be nice to have some Javascript to drive the
“slide view” browser without having to mouse over to it.</para>

<para xml:id='p6'>Another advantage over simply “cloning” your LCD is that you
can have two different resolutions. So I got to read my notes, etc.,
on my normal 1600x1200 desktop while projecting slides at 1024x768.</para>

<para xml:id='p7'>If you give presentations and you haven't tried dual
screen mode, I highly recommend it!</para>
