wsfb - video driver for wsdisplay framebuffer device
Section "Device" Identifier "devname" Driver "wsfb" ... EndSection
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(4) framebuffer driver is available on OpenBSD and NetBSD.
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
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.
