       wsfb - video driver for wsdisplay framebuffer device

       Section "Device"
         Identifier "devname"
         Driver "wsfb"

       wsfb  is  an  Xorg  driver for OpenBSD and NetBSD wsdisplay framebuffer
       devices.  This is a non-accelerated driver.  The following  framebuffer
       depths  are supported: 1, 8, 16 and 24, given that the wsdisplay device
       underneath supports them.
       A StaticGray monochrome visual is provided  for  depth  1,  all  visual
       types are supported for depth 8 and a TrueColor visual is supported for
       the other depths.  Multi-head configurations are supported.

       The wsfb driver supports all hardware  where  a  wsdisplay  framebuffer
       driver  is available on OpenBSD and NetBSD.  On OpenBSD, currently this
       includes OpenBSD/macppc,  OpenBSD/sgi,  OpenBSD/sparc,  OpenBSD/sparc64
       and  OpenBSD/alpha on TGA graphics cards.  It also supports NetBSD/i386
       using wsdisplay on vesafb(4).

       Please refer to xorg.conf(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 configuration file.  The wsfb driver picks up the currently
       used  video  mode from the framebuffer driver and uses it.  Video modes
       specifications in the configuration file are ignored.

       The following driver options are supported in the Device section:

       Option "device" "string"
              The wsdisplay framebuffer device to use.  Default  for  OpenBSD:
              /dev/ttyC0.  Default for NetBSD: /dev/ttyE0.

       Option "ShadowFB" "boolean"
              Enable  or  disable  use  of  the shadow framebuffer layer.  See
              shadowfb(4) for further information.   Default:  on  for  depths
              were it is supported, off otherwise.
              ShadowFB is currently not supported on monochrome displays.

       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.
