Virtual video card?
 

Maybe this is completely stupid, but I have an idea and would need something like this to accomplish it.

Does anyone know of (or how I would do it) to make a virtual video card.
Virtual being a video driver that would write to a file instead of the address mappings of a video card. Then I'd be able to load a x session with this and instead of it showing up on my monitor I'd get a file that a program could read.

Possibly I may not be wording my question properly.


Thanks.

I understand what you are after. Not sure if it can be done. Closest thing to a virtual interface I know of is this. http://www.xfree86.org/4.0.1/Xvfb.1.html
Not sure if the /dev can be saved to a file or not.
