bool Enable Video Mode Handling Helpers depends on FB This is used by drivers that don't provide their own (accelerated) version. Include the cfb_imageblit function for generic software image blitting. Include the cfb_copyarea function for generic software area copying. Include the cfb_fillrect function for generic software rectangle filling. an accelerated X server) and that are not frame buffer device-aware may cause unexpected results. Please note that running graphical applications that directly touch the hardware (e.g. If you are compiling for the x86 architecture, you can say Y if you want to play with it, but it is not essential.
Say Y here and to the driver for your graphics board below if you are compiling a kernel for a non-x86 architecture. Please read and the Framebuffer-HOWTO at for more information. You need a utility program called fbset to make full use of frame buffer devices. The device is accessed through special device nodes, usually located in the /dev directory, i.e. On several non-X86 architectures, the frame buffer device is the only way to use the graphics hardware. Frame buffer devices work identically across the different architectures supported by Linux and make the implementation of application programs easier and more portable at this point, an X server exists which uses the frame buffer device exclusively. 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. (on/off/module) Support for frame buffer devices The frame buffer device provides an abstraction for the graphics hardware.
