I am having a similar problem with the same hardware (the monitor is a 20"
dell though).

I've had a little success by going in to the bios and changing the boot
display to the LCD instead of LCD+DVI.  I've managed to convince ubuntu to
boot and display on the LCD once now, but it's failed other times.

For fun, I tried installing OpenSUSE 11.0 and it has the exact same problem. 
The display disappears (although one monitor doesn't show "off", it has a
light colour indicating something is lighting it up, but not with a proper
image?)

To me, it looks like the output is going to a non-existant display .. maybe
the VGA port on the laptop instead of the dock or something?  

I'd like to be able to use the laptop/monitor as a dual head, or at the very
least, use the monitor to make things easier on my eyes.  I'm going to keep
poking at this, but I am beginning to wonder if the problem is hardware more
than software.

My main trick is to boot the laptop out of the dock, then dock it and enable
the 2nd monitor, but that's not a great long term solution.

Cheers
