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 configu-
       rations are supported.

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

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

       For  this  driver  it is not required to specify modes in the screen section 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 section.  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.
