Thanks for this, and everybody elses help.  Ended up getting a G450 and
now have both monitors working (c xorg.conf below).

Have a slight problem, when I go to change resolution I get 'The X
Server does not support the XRandR extension.  Runtime resolution
changes to the display size are not available'

Have done a bit of googeling and it looks maybe the mga drivers I am
using do not support this but any insight would be, well insightful.
