NAME
fbdevhw - os-specific submodule for framebuffer device access DESCRIPTION
fbdevhw provides functions for talking to a framebuffer device. It is os-specific. It is a submodule used by other video drivers. A fbdevhw module is currently available for linux framebuffer devices. fbdev(4) is a non-accelerated driver which runs on top of the fbdevhw module. fbdevhw can be used by other drivers too, this is usually activated with `Option "UseFBDev"' in the device section.

NAME
fbdev - video driver for framebuffer device SYNOPSIS
Section "Device" Identifier "devname" Driver "fbdev" BusID "pci:bus:dev:func" ... EndSection DESCRIPTION
fbdev is an Xorg driver for framebuffer devices. This is a non-accelerated driver, the following framebuffer depths are supported: 8, 15, 16, 24. All visual types are supported for depth 8, and TrueColor visual is supported for the other depths. Multi-head configurations are supported. SUPPORTED HARDWARE
The fbdev driver supports all hardware where a framebuffer driver is available. fbdev uses the os-specific submodule fbdevhw(4) to talk to the kernel device driver. Currently a fbdevhw module is available for linux. 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 config file. The fbdev driver can pick up the currently used video mode from the framebuffer driver and will use it if there are no video modes configured. For PCI boards you might have to add a BusID line to the Device section. See above for a sample line. You can use " -scanpci" to figure out the correct values. The following driver Options are supported: Option "fbdev" "string" The framebuffer device to use. Default: /dev/fb0. Option "ShadowFB" "boolean" Enable or disable use of the shadow framebuffer layer. Default: on. 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. SEE ALSO
