       nv - NVIDIA video driver

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

       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 True-
       Color 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

       Please  refer to XF86Config(5x) for general configuration details.  This section only cov-
       ers configuration details specific to this driver.

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

       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 on OS-specific fb interface (and is not supported on all
	      OSs).  See fbdevhw(4x) 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 par-
	      ticular 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  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 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.
