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

52 Please refer to xorg.conf(5) for general configuration details. This
53 section only covers configuration details specific to this driver.
54 The driver auto-detects the chipset type and the amount of video memory
56 present for all chips.
57 The following driver Options are supported:
59 Option "HWCursor" "boolean"
61 Enable or disable the HW cursor. Default: on.
62 Option "NoAccel" "boolean"
64 Disable or enable acceleration. Default: acceleration is
65 enabled.
66 Option "UseFBDev" "boolean"
68 Enable or disable use of an OS-specific fb interface (and is not
69 supported on all OSs). See fbdevhw(4) for further information.
70 Default: off.
71 Option "CrtcNumber" "integer"
73 Many graphics cards with NVIDIA chips have two video outputs.
74 The driver attempts to autodetect which one the monitor is con‐
75 nected to. In the case that autodetection picks the wrong one,
76 this option may be used to force usage of a particular output.
77 The options are "0" or "1". Default: autodetected.
78 Option "FlatPanel" "boolean"
80 The driver usually can autodetect the presence of a digital flat
81 panel. In the case that this fails, this option can be used to
82 force the driver to treat the attached device as a digital flat
83 panel. With this driver, a digital flat panel will work only if
84 it was POSTed by the BIOS, that is, the computer must have
85 booted to the panel. If you have a dual head card you may also
86 need to set the option CrtcNumber described above. Default:
87 autodetected.
88 Option "FPDither" "boolean"
90 Many digital flat panels (particularly ones on laptops) have
91 only 6 bits per component color resolution. This option tells
92 the driver to dither from 8 bits per component to 6 before the
93 flat panel truncates it. Default: off.
94 Option "FPScale" "boolean"
96 Supported only on GeForce4 and newer chips, this option tells to
97 the driver to scale lower resolutions up to the flat panel's
98 native resolution. Default: on.
99 Option "Rotate" "CW"
101 Option "Rotate" "CCW"
103 Rotate the display clockwise or counterclockwise. This mode is
104 unaccelerated. Default: no rotation.
105 Note: The Resize and Rotate extension will be disabled if the
107 Rotate "CW" or Rotate "CCW" options are used.
108 Option "Rotate" "RandR"
110 Enable rotation of the screen using the Resize and Rotate exten‐
111 sion. This mode is unaccelerated. Default: no rotation sup‐
112 port.
113 Option "ShadowFB" "boolean"
115 Enable or disable use of the shadow framebuffer layer. Default:
116 off.
