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/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
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.
