       nv - NVIDIA video driver

       Section "Device"
	 Identifier "devname"
	 Driver	"nv"

       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.

       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, NV31, NV34, NV35, NV36, NV38

       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:

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

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

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

       Option "CrtcNumber" "integer"
	      GeForce2 MX, nForce2, Quadro4, GeForce4, Quadro FX  and  GeForce
	      FX  may  have two	video outputs.	The driver attempts to autode-
	      tect 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 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 only work if
	      it was POSTed by the BIOS, that is, the machine 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: off.

       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. This is only supported in depth	24  on
	      GeForce2	MX,  nForce2, GeForce4,	Quadro4, Geforce FX and	Quadro
	      FX.  Default: off.

       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:

       Xorg(1),	xorg.conf(5), xorgconfig(1), Xserver(1), X(7)
