Re: --base-mosaic and 2x GT240
As far as I can tell, the error messages cover it.
I did manage to get BaseMosaic going on a GTX 460 2Win - a dual GPU card, with an internal PCIe switch.
Apparently something in there made it work, maybe the Nvidia PCIe switch, which may be a 'quadro part'
Apart from that, needs to be Quadro cards in a configuration that supports SLI.
