NAME
       nv - NVIDIA video driver

SYNOPSIS

         Driver "nv"

       EndSection

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.
