     EndSection

DESCRIPTION

     wsfb is an XFree86 driver for the OpenBSD wsdisplay frame-
     buffer devices. This is a non-accelerated driver. The fol-
     lowing 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 confi-
     gurations are supported.

SUPPORTED HARDWARE

     The wsfb driver supports all hardware where a wsdisplay
     framebuffer driver is available on OpenBSD. Currently this
     includes OpenBSD/macppc, OpenBSD/sparc, OpenBSD/sparc64 and
     OpenBSD/alpha on TGA graphics cards.

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 section 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 confi-
     guration file are ignored.

     The following driver options are supported in the Device
     section:

     Option "device" "string"
          The wsdisplay framebuffer device to use. Default:
          /dev/ttyC0.

     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.
