  19. ---help---
  20. The frame buffer device provides an abstraction for the graphics
  21. hardware. It represents the frame buffer of some video hardware and
  22. allows application software to access the graphics hardware through
  23. a well-defined interface, so the software doesn't need to know
  24. anything about the low-level (hardware register) stuff.
  25. Frame buffer devices work identically across the different
  26. architectures supported by Linux and make the implementation of
  27. application programs easier and more portable; at this point, an X
  28. server exists which uses the frame buffer device exclusively.
  29. On several non-X86 architectures, the frame buffer device is the
  30. only way to use the graphics hardware.
  31. The device is accessed through special device nodes, usually located
  32. in the /dev directory, i.e. /dev/fb*.
  33. You need an utility program called fbset to make full use of frame
  34. buffer devices. Please read <file:Documentation/fb/framebuffer.txt>
  35. and the Framebuffer-HOWTO at
  36. <http://www.tahallah.demon.co.uk/programming/prog.html> for more
  37. information.
  38. Say Y here and to the driver for your graphics board below if you
  39. are compiling a kernel for a non-x86 architecture.
  40. If you are compiling for the x86 architecture, you can say Y if you
  41. want to play with it, but it is not essential. Please note that
  42. running graphical applications that directly touch the hardware
  43. (e.g. an accelerated X server) and that are not frame buffer
  44. device-aware may cause unexpected results. If unsure, say N.

  50. This enables access to the EDID transferred from the firmware.
  51. On the i386, this is from the Video BIOS. Enable this if DDC/I2C
  52. transfers do not work for your driver and if you are using
  53. nvidiafb, i810fb or savagefb.
  54. In general, choosing Y for this option is safe. If you
  55. experience extremely long delays while booting before you get
  56. something on your display, try setting this to N. Matrox cards in
  57. combination with certain motherboards and monitors are known to
  58. suffer from this problem.

  1050. also load i2c-matroxfb to get it to run.

  1054. PAL or NTSC or to swap primary and secondary head outputs.
  1055. Secondary head driver also always start in 640x480 resolution, you
  1056. must use fbset to change it.
  1057. Also do not forget that second head supports only 16 and 32 bpp
  1058. packed pixels, so it is a good idea to compile them into the kernel
  1059. too. You can use only some font widths, as the driver uses generic
