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  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 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.
