DESCRIPTION

       modesetting  is  an  Xorg  driver  for  KMS  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.  RandR 1.2 is supported.

SUPPORTED HARDWARE

       The modesetting driver supports all hardware where a KMS driver is available.  modesetting uses the Linux
       DRM KMS ioctls and dumb object create/map.

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
       modesetting driver can pick up the currently used video mode from the kernel 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.

       The following driver Options are supported:

       Option "SWcursor" "boolean"
              Selects software cursor.  The default is off.

       Option "kmsdev" "string"
              The framebuffer device to use. Default: /dev/dri/card0.

       Option "ShadowFB" "boolean"
              Enable or disable use of the shadow framebuffer layer.  Default: on.

       Option "AccelMethod" "string"
              One of "glamor" or "none".  Default: glamor

       Option "PageFlip" "boolean"
              Enable DRI3 page flipping.  The default is on.

       Option "ZaphodHeads" "string"
              Specify  the RandR output(s) to use with zaphod mode for a particular driver instance.  If you use
              this option you must use this option for all instances of the driver.
              For example: Option "ZaphodHeads" "LVDS,VGA-0" will assign xrandr outputs LVDS and VGA-0  to  this
              instance of the driver.
