Oh. How did you do this? Are you using an NVidia GPU? Does XRandR work? I couldn't get this to work at all, though I was using the closed drivers (since I couldn't find any evidence CUDA works with the open ones). Do you need the open drivers for this?

In the end I spent £30 on a second GPU. Problem solved... ish. XRandR still didn't work, and GNOME3 switched to fallback mode, which is basically GNOME2, i.e., a totally different window manager and a totally different shell.

I have no opinion on the performance on Windows vs that on Linux (not a concern, hence the £30 GPU...) but this whole situation was certainly a lot less hassle on Windows ;)

I used xrandr --setprovideroutputsource to set one image provider as the source of the others image.
