I have two monitors set to TwinView in Nvidia's settings. When I run Boxee it expands over both of them. Is it possible to run it in just one of them?
You can press
\ to toggle full screen mode. Then you could at least run it in windowed mode on a single screen.
For a more complete solution, this thread on the Boxee forum may be helpful. It's been a while since I used Boxee on a dual screen system, but when I did, I used something similar to what's outline there.
Also ive noticed that if you enable 'twinview' in the nvidia-settings tool and click apply. That the current session will not competely work as expected. A logout/back in will enable twinview fully, and Hopefully apps will then fullscreen to one or the other monitor.
alternative work around. Compiz can force a window to be on a specific monitor/fullscreened/specific size.
So Try enabling twinview in nvidia settings, log out/back in. If that fails dig into compiz plugins.
