nv - NVIDIA video driver
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.
The nv driver supports PCI and AGP video cards based on the following
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
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
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.
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".
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:
XFree86(1), XF86Config(5), xf86config(1), Xserver(1), X(7)
