       nv - NVIDIA video driver

SYNOPSIS
       Section "Device"
	 Identifier "devname"
	 Driver	"nv"
	 ...
       EndSection

DESCRIPTION
       nv  is  an  Xorg	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

CONFIGURATION DETAILS
       Please  refer  to xorg.conf(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 for pre-G80 hardware:

       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(4x) 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 "Dualhead" "boolean"
	      Enables simple VBE-based dual head mode.	 This  sets  the  same
	      resolution  on both outputs and lays them	out side-by-side.  The
	      screens will be panned together as one big metamode if the  vir-
	      tual desktop is larger than both screens combined.

       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 "CW" or Rotate "CCW" options are used.

       Option "Rotate" "RandR"
	      Enable rotation of the screen using the Resize and Rotate	exten-
	      sion.  This mode is unaccelerated.  Default:  no	rotation  sup-
	      port.

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

       The following driver Options are	available for G80 and higher:

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

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

       Option "AccelMethod" "string"
	      Choose acceleration architecture,	either "XAA" or	"EXA".	XAA is
	      the old but stable architecture.	 EXA  is  newer	 and  supports
	      resizing	the desktop larger than	it started out with RandR 1.2.
	      If you choose to use EXA,	you might also consider	setting	Option
	      "MigrationHeuristic"  "greedy" to	improve	performance.  Default:
	      XAA.

       Option "FPDither" "boolean"
	      Enable or	disable	flat panel dithering  by  default.   Dithering
	      can  also	 be  enabled  or disabled using	the RandR 1.2 "dither"
	      output property.	Default: off.

       Option "AllowDualLinkModes" "boolean"
	      Allow validation of dual-link DVI	modes.	Not all	GPUs are  con-
	      figured  at  boot	 time to be able to handle dual-link modes, so
	      they are disabled	by default.

       The following RandR 1.2 properties are available	for flat panels	on G80
       and higher GPUs:

       dither Enable  or disable flat panel dithering.	Valid values: 0	(off),
	      1	(on).

       scale  Control how the image is scaled to fit  the  flat	 panel.	  Note
	      that some	flat panels perform their own scaling, overriding this
	      option.  "off" is	not  valid  for	 laptop	 flat  panels  (LVDS).
	      Valid  values:  "off", "aspect", "fill", and "center".  Default:
	      "aspect".
