DESCRIPTION

       nv  is  an  XFree86  driver  for	 NVIDIA video cards.  The
       driver supports full 2D acceleration and provides  support
       for  the	 following  framebuffer depths: 8, 15, 16 (except
       Riva128) and 24.	 All visual types are supported for depth
       8, TrueColor and DirectColor visuals are supported for the
       other depths with the exception of the Riva128 which  only
       supports TrueColor in the higher depths.



SUPPORTED HARDWARE

       The  nv	driver	supports PCI and AGP video cards based on
       the following NVIDIA chips:

       RIVA 128		     NV3

       RIVA TNT		     NV4

       RIVA TNT2	     NV5

       GeForce 256, QUADRO   NV10

       GeForce2, QUADRO2     NV11 & NV15

       GeForce3, QUADRO DCC  NV20

       nForce, nForce2	     NV1A, NV1F

       GeForce4, QUADRO4     NV17, NV18, NV25, NV28

       GeForce FX, QUADRO FX NV30


CONFIGURATION DETAILS

       Please refer to XF86Config(5)  for  general  configuration
       details.	  This	section only covers configuration details
       specific to this driver.

       The driver auto-detects the chipset type and the amount of
       video memory present for all chips.

       The following driver Options are supported:

       Option "HWCursor" "boolean"
	      Enable or disable the HW cursor.	Default: on.



4.3.0			     Version				1





NV(4)			     XFree86			    NV(4)


       Option "NoAccel" "boolean"
	      Disable or enable acceleration.  Default: accelera
	      tion is enabled.

       Option "UseFBDev" "boolean"
	      Enable or disable use of on OS-specific  fb  inter
	      face  (and is not supported on all OSs).	See fbde
	      vhw(4) for further information.  Default: off.

       Option "CrtcNumber" "integer"
	      nForce2, Quadro4, GeForce4 and NV30  may	have  two
	      video  outputs.	The driver attempts to autodetect
	      which one the monitor is connected to.  In the case
	      that autodetection picks the wrong one, this option
	      may be used to force usage of a particular  output.
	      The options are "0" or "1".  Default: autodetected.

       Option "FlatPanel" "boolean"
	      The driver usually cannot autodetect  the	 presence
	      of  a  flat panel so this option should be set when
	      used with a flat panel.  With this  driver  a  flat
	      panel  will only work if it was POSTed by the BIOS,
	      that is, the machine must have booted to the panel.
	      Default: off.

       Option "FPDither" "boolean"
	      Most  digital flat panels have only 6 bits per com
	      ponent color resolution.	 This  option  tells  the
	      driver  to  dither  from	8 bits per component to 6
	      before the flat panel truncates it.  This	 is  only
	      suported	in  depth  24 on NV11, nForce2, GeForce4,
	      Quadro4 and NV30.	 Default: off.

       Option "Rotate" "CW"

       Option "Rotate" "CCW"
	      Rotate the display clockwise  or	counterclockwise.
	      This  mode is unaccelerated.  Default: no rotation.

	      Note: Option Rotate does not work unless the Resize
	      and Rotate extension has been turned off.

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