NAME
       nv - NVIDIA video driver

SYNOPSIS
       Section "Device"

	 Driver	"nv"
	 ...
       EndSection

DESCRIPTION
       nv is an	XFree86	driver for NVIDIA video	cards.	The driver supports 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, PCI-Express 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, NV31, NV34, NV35, NV36, NV37, NV38

       GeForce 6XXX	     NV40, NV41, NV43, NV44, NV45, C51

       GeForce 7XXX	     G70, G71, G72, G73

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.

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

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

       Option "CrtcNumber" "integer"
	      Many graphics cards with NVIDIA chips have  two  video  outputs.
	      The  driver attempts to autodetect which one the monitor is con-
	      nected 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 can autodetect	the presence of	a digital flat
	      panel.   In the case that	this fails, this option	can be used to
	      force the	driver to treat	the attached device as a digital  flat
	      panel.  With this	driver,	a digital flat panel will work only if
	      it was POSTed by the BIOS,  that	is,  the  computer  must  have
	      booted  to the panel.  If	you have a dual	head card you may also
	      need to set the option  CrtcNumber  described  above.   Default:
	      autodetected.

       Option "FPDither" "boolean"
	      Many  digital  flat  panels  (particularly ones on laptops) have
	      only 6 bits per component	color resolution.  This	 option	 tells
	      the  driver  to dither from 8 bits per component to 6 before the
	      flat panel truncates it.	Default: off.

       Option "FPScale"	"boolean"
	      Supported	only on	GeForce4 and newer chips, this option tells to
	      the  driver  to  scale  lower resolutions	up to the flat panel's
	      native resolution.  Default: on.

       Option "Rotate" "CW"

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

	      Note:  The  Resize  and Rotate extension will be disabled	if the
	      Rotate option is used.

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