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, NV38


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 "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.
