      fbdev - video driver for framebuffer device
  • SYNOPSIS

   Identifier \*q  devname q
     Driver \*qfbdev\*q     BusID  \*qpci: bus : dev : func q   ...

  • 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(4x) to talk
      to the kernel
      device driver.  Currently a fbdevhw module is available for 1.
  • CONFIGURATION DETAILS
      Please refer to xorg.conf(5x) 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 qXorg
      -scanpciq
      to figure out the correct values.
      The following driver
      Options are supported:
      Option \*qfbdev\*q \*q string q
      The framebuffer device to use. Default: /dev/fb0.
      Option \*qShadowFB\*q \*q boolean q
      Enable or disable use of the shadow framebuffer layer.  Default: on.
      Option \*qRotate\*q \*q string q
      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.
