I just spent the past three hours or so trying to get my 2005FPW monitor working on Gentoo with my T42 docked. It was not an easy process and I have to go to bed, but there were a couple things that pointed me in the right direction.
<li><a href="http://www.tuxme.com/node/544">Ubuntu on a T42</a>, specifically the Video portion, and even more specifically the MonitorLayout option actually got the monitor functional.</li>
<li>The <a href="http://www.horstmann.com/linux-thinkpad-t41p.html">ModeLine from this page</a> gave me a proper resolution.</li>
This FreeBSD post on dual monitors also helped quite a bit, but it was those two links above that made it perfect.
Now I have to crash. Pulling the night shift tomorrow, that’s why I’m up nice and late. :-)
