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?

When you say "so that X-server can run normally on that?" is that the second, or the first? – No Time Jun 1 '14 at 21:32
I mean that x-server should run on the primary monitor as it is, but secondary monitor can be used to directly write data on the framebuffer. – user3692512 Jun 2 '14 at 20:58
