DESCRIPTION
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.
SUPPORTED HARDWARE
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).
CONFIGURATION DETAILS
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 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 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.
