not sure exactly what the question is but here is what I am doing that
seems to work.

I don't have an xorg.conf file so you might try
mv /etc/X11/xorg.conf /etc/X11/xorg.conf-bak
just to keep it around but not loaded

Then make sure that the monitor is attached when you restart so that it
fully senses it.

Log in as user

Run 'systemsettings' and choose 'Display'

You should be able to pick the resolution for the built-in laptop and
the monitor separately - click Apply

I **think** that the nv module might be better than vesa if you are
going to use an open source video driver.
