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.
22
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 G80, G84, G86

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