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 NVIDIA chips:
- RIVA 128
- NV3
- RIVA
TNT
- NV4
- RIVA TNT2
- NV5
- GeForce 256, QUADRO
- NV10
- GeForce2, QUADRO2

- 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
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 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.
