is an __xservername__ driver for NVIDIA video cards. The driver supports 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.
24

.SH CONFIGURATION DETAILS
63
Please refer to __xconfigfile__(__filemansuffix__) for general configuration
64
details. This section only covers configuration details specific to this
67
The driver auto-detects the chipset type and the amount of video memory
68
present for all chips.
74
.BI "Option \*qHWCursor\*q \*q" boolean \*q
75
Enable or disable the HW cursor. Default: on.
77
.BI "Option \*qNoAccel\*q \*q" boolean \*q
78
Disable or enable acceleration. Default: acceleration is enabled.
80
.BI "Option \*qUseFBDev\*q \*q" boolean \*q
81
Enable or disable use of an OS-specific fb interface (and is not supported
82
on all OSs). See fbdevhw(__drivermansuffix__) for further information.
85
.BI "Option \*qCrtcNumber\*q \*q" integer \*q
86
Many graphics cards with NVIDIA chips have two video outputs.
87
The driver attempts to autodetect
88
which one the monitor is connected to. In the case that autodetection picks
89
the wrong one, this option may be used to force usage of a particular output.
90
The options are "0" or "1".
91
Default: autodetected.
93
.BI "Option \*qFlatPanel\*q \*q" boolean \*q
94
The driver usually can autodetect the presence of a digital flat panel. In
95
the case that this fails, this option can be used to force the driver to
96
treat the attached device as a digital flat panel. With this
97
driver, a digital flat panel will work only if it was POSTed by the BIOS,
99
must have booted to the panel. If you have a dual head card
100
you may also need to set the option CrtcNumber described above.
101
Default: autodetected.
103
.BI "Option \*qFPDither\*q \*q" boolean \*q
104
Many digital flat panels (particularly ones on laptops) have only 6 bits
105
per component color resolution.
106
This option tells the driver to dither from 8 bits per component to 6 before
107
the flat panel truncates it.
110
.BI "Option \*qFPScale\*q \*q" boolean \*q
111
Supported only on GeForce4 and newer chips, this option
112
tells to the driver to scale lower resolutions up to the flat panel's native
113
resolution. Default: on.
115
.BI "Option \*qScalingMode\*q \*q" string \*q
116
Only for the randr-1.2 driver, this allows to set the DFP scaling mode.
117
The options are "fullscreen", "aspect", "noscale" and "panel". Default: "aspect".
119
.BI "Option \*qRotate\*q \*qCW\*q"
121
.BI "Option \*qRotate\*q \*qCCW\*q"
122
Rotate the display clockwise or counterclockwise. This mode is unaccelerated.
123
Default: no rotation.
125
Note: The Resize and Rotate extension will be disabled if the Rotate "CW" or
126
Rotate "CCW" options are used.
128
.BI "Option \*qRotate\*q \*qRandR\*q"
129
Enable rotation of the screen using the Resize and Rotate extension.
130
This mode is unaccelerated.
131
Default: no rotation support.
133
.BI "Option \*qShadowFB\*q \*q" boolean \*q
134
Enable or disable use of the shadow framebuffer layer. Default: off.
