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 and AGP video cards based on the following NVIDIA chips:

    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 xorg.conf(5x) 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 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 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.
