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 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
GeForce 6XXX NV40, NV41, NV43, NV44, NV45, C51
GeForce 7XXX G70, G71, G72, G73
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:
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 "ScalingMode" "string"
Only for the randr-1.2 driver, this allows to set the DFP scal‐
ing mode. The options are "fullscreen", "aspect", "noscale" and
"panel". Default: "aspect".
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.
