framebuffer

I have 2 monitors connected to the PC, one in HDMI, one in DVI. I have Intel integrated graphics HD4600

Now as far my understanding, both the monitors is connected at the same framebuffer /dev/fb0

How can I detach them and create 2 frame buffers at startup, so that I can directly write to the second monitor, by writing on the /dev/fb1, and not hamper the /dev/fb0, so that x-server can run normally on that?
