What is FB in Linux?
The frame buffer device provides an abstraction for the graphics hardware. It represents the frame buffer of some video hardware and allows application software to access the graphics hardware through a well-defined interface, so the software doesn’t need to know anything about the low-level (hardware register) stuff.
How do I enable framebuffer?
The framebuffer console can be enabled by using your favorite kernel configuration tool. It is under Device Drivers->Graphics Support-> Console display driver support->Framebuffer Console Support. Select ‘y’ to compile support statically or ‘m’ for module support.

GOTCHA: A common bug report is enabling the framebuffer without enabling the framebuffer console. Depending on the driver, you may get a blanked or garbled display, but the system still boots to completion. If you are fortunate to have a driver that does not alter the graphics chip, then you will still get a VGA console.
