In multi-head setups that use a single large virtual display, fullscreen would be the whole virtual display, including dead space. It would be convenient if we could select only one physical display. The geometry of each physical display should be available via the X server's XINERAMA information, such as:

xdpyinfo -ext XINERAMA | grep -w '^ *head'

The thing we should discuss here, is that whether this information is reasonably universally available and reliable.

So, if you use multi-head, please _reply the output of the the command line above, along with your video card/driver_.

If this is indeed a reliable way to get the geometry of the pysical displays, we've got a deal :) The hypothetical syntax would be:

ffcast -x 1 # select head #1
ffcast -x 0,2 # select head #0 and #2; they will be union'd as usual...
