How can I set up twin view on 11.04 with a Matrox G400/G450?

Question

I've been trying, quite unsuccessfully, to set up "twin view" on 11.04 with a Matrox G400/G450.

At this point I can't recall what I may have tried.

Currently each monitor is displaying the same video and pressing "Detect Monitors" within System -> Preferences -> Monitors does nothing.

I have scoured the interwebs for instructions, tried several of them to no avail.

Most recently I read through several threads on the Ubuntu forums and it seems many others have the same problem with no resolution.

Thank you for your time!

Did you see this website and the example xorg.conf

The important part to checkout is Section "ServerLayout" at the bottom of the file.

I also have this exact same requirement with the same issue at the moment. Please could someone suggest some ideas. One monitor is a Belinea LCD. The other is a LCD TV with PC input. Here are some more details about the graphics card.
