Hi all,

My Linux box is running Ubunt Natty. I have an nVidia 8400GS video card with
a dual (DVI and D-Sub) head.

I'd like to connect the D-Sub head to my LCD TV and run specific
applications on it - like movies or presentations etc.

How do I tell the movie player to run on the other head?

How do i even find out which is which?

I have a 19" LCD monitor connected to the DVI head, the D-Sub is not in use
for now...
