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 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, NV40,
                             NV41, NV43, NV44, NV45


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 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 "FPScale" "boolean"
              Supported  only  on GeForce4, Quadro4, Geforce FX and Quadro FX.
              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.
