DESCRIPTION

       nv  is  an  XFree86  driver for NVIDIA video cards.  The driver supports full 2D acceleration and provides support for the following frame-
       buffer depths: 8, 15, 16 (except Riva128) and 24.  All visual types are supported for depth 8, TrueColor and DirectColor visuals  are  sup-
       ported 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(5x) 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 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  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 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.
