I now have the correct nvidia drivers working, and tried an external monitor. Home it's a single Dell 24' ultrasharp, work it's 3 22' monitors into a matrox triplehead to go, but had both working with a diff distro (should have saved x config).
But alas, nvidia-settings shows the other monitor, I can select it, the default res only goes as high as 1024x768 but even I select that, reboot, disable the laptop screen as I dont want that on, the laptop goes black and the monitor never comes on. I am thinking I may need to edit the conf by hand, but a little rusty as to both what to change, and what can be removed.
If I can get this working with the single dell, the work should be just as easy as it's just a resolution change, but here is the file;
