17 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 SUPPORTED HARDWARE
27 driver supports PCI, PCI-Express and AGP video cards based on the following NVIDIA chips:
38 .B GeForce 256, QUADRO
44 .B GeForce3, QUADRO DCC
51 NV17, NV18, NV25, NV28
53 .B GeForce FX, QUADRO FX
54 NV30, NV31, NV34, NV35, NV36, NV37, NV38
57 NV40, NV41, NV43, NV44, NV45, C51
62 .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 \*qRotate\*q \*qCW\*q"
117 .BI "Option \*qRotate\*q \*qCCW\*q"
118 Rotate the display clockwise or counterclockwise. This mode is unaccelerated.
119 Default: no rotation.
121 Note: The Resize and Rotate extension will be disabled if the Rotate "CW" or
122 Rotate "CCW" options are used.
124 .BI "Option \*qRotate\*q \*qRandR\*q"
125 Enable rotation of the screen using the Resize and Rotate extension.
126 This mode is unaccelerated.
127 Default: no rotation support.
129 .BI "Option \*qShadowFB\*q \*q" boolean \*q
130 Enable or disable use of the shadow framebuffer layer. Default: off.
