DESCRIPTION
nv is an XFree86 driver for NVIDIA video cards. The
driver supports full 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:
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
CONFIGURATION DETAILS
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.
4.3.0 Version 1
NV(4) XFree86 NV(4)
Option "NoAccel" "boolean"
Disable or enable acceleration. Default: accelera
tion is enabled.
Option "UseFBDev" "boolean"
Enable or disable use of on OS-specific fb inter
face (and is not supported on all OSs). See fbde
vhw(4) for further information. Default: off.
Option "CrtcNumber" "integer"
nForce2, Quadro4, GeForce4 and NV30 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 cannot autodetect the presence
of a flat panel so this option should be set when
used with a flat panel. With this driver a flat
panel will only work if it was POSTed by the BIOS,
that is, the machine must have booted to the panel.
Default: off.
Option "FPDither" "boolean"
Most digital flat panels have only 6 bits per com
ponent 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
suported in depth 24 on NV11, nForce2, GeForce4,
Quadro4 and NV30. Default: off.
Option "Rotate" "CW"
Option "Rotate" "CCW"
Rotate the display clockwise or counterclockwise.
This mode is unaccelerated. Default: no rotation.
Note: Option Rotate does not work unless the Resize
and Rotate extension has been turned off.
Option "ShadowFB" "boolean"
Enable or disable use of the shadow framebuffer
layer. Default: off.
