I have set up dual screen under Ubuntu 12.04. I have a GeForce 8500 GT and have used the nVidia control panel to set up dual screen in "Separate screen mode". Here's the resulting xorg.conf

All well and good and I have a nice blank XWindow displayed on my TV (the 2nd monitor). I then fire up XBMC from a terminal on the PC monitor using

DISPLAY=:0.1 xbmc

XBMC fires up quite nicely on the TV however I can no longer use the main PC monitor / mouse / keyboard as XBMC on the TV screen seems to have focus. I was hoping to have XBMC running on the TV and let the kids use the MCE remote whilst I get on with my work on the PC monitor.

Does anyone have any idea how to overcome this? I'm presuming there's some xorg.conf fun and games needed but I've no idea where to start to be honest.
