Re: basemosaic linux
BaseMosaic may not be 'supported' on GeForce cards, but it works on some stuff. One example is the eVGA 2Win cards - with two identical GPUs, linked by an internal PCIe switch. That switch is an NVidia part, afaict, which may be why it works.
Anyhow, you can use BaseMosaic on those. There's a lot of limitations, like with SLI-mosaic - you can't run other GPUs for example. But it works, or did recently (290.10).
