DESCRIPTION

       nv  is  an  Xorg 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 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

       GeForce 8XXX          G80

CONFIGURATION DETAILS

       Please  refer  to xorg.conf(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 for pre-G80 hardware:

       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 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 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 "CW" or Rotate "CCW" options are used.

       Option "Rotate" "RandR"
              Enable rotation of the screen using the Resize and Rotate exten-
              sion.   This  mode  is unaccelerated.  Default: no rotation sup-
              port.

       Option "ShadowFB" "boolean"
              Enable or disable use of the shadow framebuffer layer.  Default:
              off.

       The following driver Options are available for G80:

       Option "HWCursor" "boolean"
              Enable or disable the hardware cursor.  Default: on.

       Option "NoAccel" "boolean"
              Disable   or  enable  acceleration.   Default:  acceleration  is
              enabled.

       Option "BackendMode" "mode"
              Designate a mode to be used as the  physical  mode  driving  the
              display.   The  screen will be scaled to fit the requested mode.
              For example, if Option "BackendMode" "1280x1024"  is  specified,
              the  monitor  will  always  display  the  1280x1024 mode and the
              screen will be scaled to match.
