NAME
       fbdev - video driver for	framebuffer device

SYNOPSIS
       Section "Device"
	 Identifier "devname"
	 Driver	"fbdev"
	 BusID	"pci:bus:dev:func"
	 ...
       EndSection

DESCRIPTION
       fbdev  is  an  XFree86  driver for framebuffer devices.	This is	a non-
       accelerated driver, the following framebuffer depths are	supported:  8,
       15,  16,	24.  All visual	types are supported for	depth 8, and TrueColor
       visual is supported for the other  depths.   Multi-head	configurations
       are supported.

SUPPORTED HARDWARE
       The  fbdev  driver  supports all	hardware where a framebuffer driver is
       available.  fbdev uses the os-specific submodule	fbdevhw(4) to talk  to
       the  kernel device driver.  Currently a fbdevhw module is available for
       linux.

CONFIGURATION DETAILS
       Please refer to XF86Config(5) for general configuration details.	  This
       section only covers configuration details specific to this driver.

       For  this driver	it is not required to specify modes in the screen sec-
       tion of the config file.	 The fbdev driver can pick  up	the  currently
       used  video  mode  from the framebuffer driver and will use it if there
       are no video modes configured.

       For PCI boards you might	have to	add a BusID line to  the  Device  sec-
       tion.   See above for a sample line.  You can use "XFree86 -scanpci" to
       figure out the correct values.

       The following driver Options are	supported:

       Option "fbdev" "string"
	      The framebuffer device to	use. Default: /dev/fb0.

       Option "ShadowFB" "boolean"
	      Enable or	disable	use of the shadow framebuffer layer.  Default:
	      on.

       Option "Rotate" "string"
	      Enable  rotation	of  the	display. The supported values are "CW"
	      (clockwise, 90 degrees), "UD" (upside  down,  180	 degrees)  and
	      "CCW"  (counter  clockwise,  270	degrees).  Implies  use	of the
	      shadow framebuffer layer.	  Default: off.
