I think they might go 'free software' later. The rumours about this haven been
circulating for months with some substance from people who are close to
NVidia. Now that OpenGL is Free software...

> Multimonitor Support in WDDM
>
> On Windows Vista, older XPDM drivers still work and the multi-monitor
> behavior with XPDM drivers hasn't changed, because the operating
> system uses the legacy graphics stack.
>
> However, the Windows Vista Display Driver Model (WDDM) brings
> fundamental changes to the management of multiple graphics adapters
> and external displays. This includes a new restriction, because WDDM
> drivers do not support "heterogeneous multi-adapter" multi-monitor
> implementations. Specifically:
>
> o All graphics adapters in a system must use the same display driver
> model. That is, all of them should either be running XPDM or WDDM.
> The driver models are mutually exclusive, and Windows Vista does not
> allow the simultaneous loading of both an XPDM driver and a WDDM
> driver.
>
> o If multiple graphics adapters are present in a system, all of them
> must use the same WDDM driver. If there are two graphics adapters
> with WDDM drivers from two different manufacturers, then Windows will
> disable one of them. The VGA adapter will be enabled, and the second
> device will be disabled.
>
> There's a lot more tinkering described at that site.

> Systems that are dual monitor capable but ship without a monitor must
> ship with 256MB of memory for graphics to support AERO.
> Testing with pre-production versions of Windows Vista
> Initial testing indicates that while some single channel systems can
> run Aero, system performance may depend on applications, and minor
> system or driver changes could result in Aero being disabled later.
What a nuisance. Even gNewSense is better.
