Re: [Xen-users] Help with VGA passthrough

RDP doesn't require any VGA adapters, however it will not allow you to modify 
VGA adapter settings through a remote desktop session.

I'm pretty sure RDP doesn't actually require any VGA cards to function, it does 
it's own thing completely independently.

It sounds like you are losing VNC access once the ATI driver loads, but the ATI 
card then ends up not getting used. I've never seen that happen, usually if 
something goes wrong at this point, it's a BSOD which dumps out to the VNC 
console on the emulated VGA device.
