Dual monitor possible?

[Brian McKee]

If it's on the new plug it's using the new card.  That means the
'fuzion' card is actually a rebranded nVidia Fx5500 which makes sense
according to the fuzion web site.

Now where the heck did your old Geforce MX4 go?

Are you sure you haven't bumped the cards around so that they aren't
quite seated right?

lspci should show it whether linux is using it or not.

Can you try reseating the cards (with the power off) and then try
lspci without the grep?
