is an XFree86 driver for NVIDIA video cards. The driver supports full 2D
18
acceleration and provides support for the following framebuffer depths:
19
8, 15, 16 (except Riva128) and 24. All
20
visual types are supported for depth 8, TrueColor and DirectColor
21
visuals are supported for the other depths with the exception of
22
the Riva128 which only supports TrueColor in the higher depths.

.SH SUPPORTED HARDWARE
27
driver supports PCI and AGP video cards based on the following NVIDIA chips:

44
.B GeForce3, QUADRO DCC
51
NV17, NV18, NV25, NV28

.SH CONFIGURATION DETAILS
56
Please refer to XF86Config(__filemansuffix__) for general configuration
57
details. This section only covers configuration details specific to this
60
The driver auto-detects the chipset type and the amount of video memory
61
present for all chips.
67
.BI "Option \*qHWCursor\*q \*q" boolean \*q
68
Enable or disable the HW cursor. Default: on.
70
.BI "Option \*qNoAccel\*q \*q" boolean \*q
71
Disable or enable acceleration. Default: acceleration is enabled.
73
.BI "Option \*qUseFBDev\*q \*q" boolean \*q
74
Enable or disable use of on OS-specific fb interface (and is not supported
75
on all OSs). See fbdevhw(__drivermansuffix__) for further information.
78
.BI "Option \*qCrtcNumber\*q \*q" integer \*q
79
nForce2, Quadro4, GeForce4 and NV30 may have two video outputs.
80
The driver attempts to autodetect
81
which one the monitor is connected to. In the case that autodetection picks
82
the wrong one, this option may be used to force usage of a particular output.
83
The options are "0" or "1".
84
Default: autodetected.
86
.BI "Option \*qFlatPanel\*q \*q" boolean \*q
87
The driver usually cannot autodetect the presence of a flat panel so
88
this option should be set when used with a flat panel. With this driver
89
a flat panel will only work if it was POSTed by the BIOS, that is, the
90
machine must have booted to the panel.
93
.BI "Option \*qFPDither\*q \*q" boolean \*q
94
Most digital flat panels have only 6 bits per component color resolution.
95
This option tells the driver to dither from 8 bits per component to 6 before
96
the flat panel truncates it. This is only suported in depth 24 on NV11,
97
nForce2, GeForce4, Quadro4 and NV30.
100
.BI "Option \*qRotate\*q \*qCW\*q"
102
.BI "Option \*qRotate\*q \*qCCW\*q"
103
Rotate the display clockwise or counterclockwise. This mode is unaccelerated.
104
Default: no rotation.
106
Note: Option Rotate does not work unless the Resize and Rotate extension has
109
.BI "Option \*qShadowFB\*q \*q" boolean \*q
110
Enable or disable use of the shadow framebuffer layer. Default: off.
