       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


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


       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
              For  example: Option "ZaphodHeads" "LVDS,VGA-0" will assign xrandr outputs LVDS and
              VGA-0 to this instance of the driver.
