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

25 The nv driver supports PCI, PCI-Express and AGP video cards based on
26 the following NVIDIA chips:
27 RIVA 128 NV3
29 RIVA TNT NV4
31 RIVA TNT2 NV5
33 GeForce 256, Quadro NV10
35 GeForce2, Quadro2 NV11 & NV15
37 GeForce3, Quadro DCC NV20
39 nForce, nForce2 NV1A, NV1F
41 GeForce4, Quadro4 NV17, NV18, NV25, NV28
43 GeForce FX, Quadro FX NV30, NV31, NV34, NV35, NV36, NV37, NV38
45 GeForce 6XXX NV40, NV41, NV43, NV44, NV45, C51
47 GeForce 7XXX G70, G71, G72, G73
49 GeForce 8XXX, GeForce 9XXX
51 G80, G84, G86, G92, G94, G96, G98
52 GeForce GTX GT200

56 Please refer to xorg.conf(5) for general configuration details. This
57 section only covers configuration details specific to this driver.
58 The driver auto-detects the chipset type and the amount of video memory
60 present for all chips.
61 The following driver Options are supported for pre-G80 hardware:
63 Option "HWCursor" "boolean"
65 Enable or disable the HW cursor. Default: on.
66 Option "NoAccel" "boolean"
68 Disable or enable acceleration. Default: acceleration is
69 enabled.
70 Option "UseFBDev" "boolean"
72 Enable or disable use of an OS-specific fb interface (and is not
73 supported on all OSs). See fbdevhw(4) for further information.
74 Default: off.
75 Option "CrtcNumber" "integer"
77 Many graphics cards with NVIDIA chips have two video outputs.
78 The driver attempts to autodetect which one the monitor is con‐
79 nected to. In the case that autodetection picks the wrong one,
80 this option may be used to force usage of a particular output.
81 The options are "0" or "1". Default: autodetected.
82 Option "Dualhead" "boolean"
84 Enables simple VBE-based dual head mode. This sets the same
85 resolution on both outputs and lays them out side-by-side. The
86 screens will be panned together as one big metamode if the vir‐
87 tual desktop is larger than both screens combined.
88 Option "FlatPanel" "boolean"
90 The driver usually can autodetect the presence of a digital flat
91 panel. In the case that this fails, this option can be used to
92 force the driver to treat the attached device as a digital flat
93 panel. With this driver, a digital flat panel will work only if
94 it was POSTed by the BIOS, that is, the computer must have
95 booted to the panel. If you have a dual head card you may also
96 need to set the option CrtcNumber described above. Default:
97 autodetected.
98 Option "FPDither" "boolean"
100 Many digital flat panels (particularly ones on laptops) have
101 only 6 bits per component color resolution. This option tells
102 the driver to dither from 8 bits per component to 6 before the
103 flat panel truncates it. Default: off.
104 Option "FPScale" "boolean"
106 Supported only on GeForce4 and newer chips, this option tells to
107 the driver to scale lower resolutions up to the flat panel's
108 native resolution. Default: on.
109 Option "Rotate" "CW"
111 Option "Rotate" "CCW"
113 Rotate the display clockwise or counterclockwise. This mode is
114 unaccelerated. Default: no rotation.
115 Note: The Resize and Rotate extension will be disabled if the
117 Rotate "CW" or Rotate "CCW" options are used.
118 Option "Rotate" "RandR"
120 Enable rotation of the screen using the Resize and Rotate exten‐
121 sion. This mode is unaccelerated. Default: no rotation sup‐
122 port.
123 Option "ShadowFB" "boolean"
125 Enable or disable use of the shadow framebuffer layer. Default:
126 off.
127 The following driver Options are available for G80 and higher:
129 Option "HWCursor" "boolean"
131 Enable or disable the hardware cursor. Default: on.
132 Option "NoAccel" "boolean"
134 Disable or enable acceleration. Default: acceleration is
135 enabled.
136 Option "AccelMethod" "string"
138 Choose acceleration architecture, either "XAA" or "EXA". XAA is
139 the old but stable architecture. EXA is newer and supports
140 resizing the desktop larger than it started out with RandR 1.2.
141 If you choose to use EXA, you might also consider setting Option
142 "MigrationHeuristic" "greedy" to improve performance. Default:
143 XAA.
144 Option "FPDither" "boolean"
146 Enable or disable flat panel dithering by default. Dithering
147 can also be enabled or disabled using the RandR 1.2 "dither"
148 output property. Default: off.
149 Option "AllowDualLinkModes" "boolean"
151 Allow validation of dual-link DVI modes. Not all GPUs are con‐
152 figured at boot time to be able to handle dual-link modes, so
153 they are disabled by default.
154 The following RandR 1.2 properties are available for flat panels on G80
156 and higher GPUs:
157 dither Enable or disable flat panel dithering. Valid values: 0 (off),
159 1 (on).
160 scale Control how the image is scaled to fit the flat panel. Note
162 that some flat panels perform their own scaling, overriding this
163 option. "off" is not valid for laptop flat panels (LVDS).
164 Valid values: "off", "aspect", "fill", and "center". Default:
165 "aspect".
