nv - NVIDIA video driver
nv is an Xorg driver for NVIDIA video cards. The driver supports
2D acceleration and provides support for the following framebuffer depths:
8, 15, 16 (except Riva128) and 24. All visual types are supported for depth
8, TrueColor and DirectColor visuals are supported for the other depths
with the exception of the Riva128 which only supports TrueColor in the
The nv driver supports PCI and AGP video
cards based on the following NVIDIA chips:
Please refer to xorg.conf(5x)
for general configuration details.
This section only covers configuration details specific to this driver.
- RIVA 128
- RIVA TNT
- GeForce 256, QUADRO
- GeForce2, QUADRO2
- NV11 & NV15
- nForce, nForce2
- NV1A, NV1F
- GeForce4, QUADRO4
- NV17, NV18,
- GeForce FX, QUADRO FX
- NV30, NV31, NV34, NV35, NV36, NV38
The driver auto-detects the chipset type and the amount of video memory
present for all chips.
The following driver Options are supported:
include: David McKay, Jarno Paananen, Chas Inman, Dave Schmenk, Mark Vojkovich
- Enable or disable the HW cursor. Default: on.
- Disable or enable acceleration. Default: acceleration
- Option "UseFBDev" "boolean"
- Enable or disable use of on OS-specific
fb interface (and is not supported on all OSs). See fbdevhw(4)
information. Default: off.
- Option "CrtcNumber" "integer"
- GeForce2 MX, nForce2,
Quadro4, GeForce4, Quadro FX and GeForce FX may have two video outputs.
The driver attempts to autodetect which one the monitor is connected
to. In the case that autodetection picks the wrong one, this option may
be used to force usage of a particular output. The options are "0" or "1".
- Option "FlatPanel" "boolean"
- The driver usually can
autodetect the presence of a digital flat panel. In the case that this
fails, this option can be used to force the driver to treat the attached
device as a digital flat panel. With this driver, a digital flat panel
will only work if it was POSTed by the BIOS, that is, the machine must
have booted to the panel. If you have a dual head card you may also need
to set the option CrtcNumber described above. Default: off.
- Option "FPDither"
- Many digital flat panels (particularly ones on laptops) have
only 6 bits per component color resolution. This option tells the driver
to dither from 8 bits per component to 6 before the flat panel truncates
it. This is only supported in depth 24 on GeForce2 MX, nForce2, GeForce4,
Quadro4, Geforce FX and Quadro FX. Default: off.
- Option "Rotate" "CW"
- Rotate the display clockwise or counterclockwise. This mode
is unaccelerated. Default: no rotation.
Note: The Resize and Rotate extension
will be disabled if the Rotate option is used.
- Option "ShadowFB" "boolean"
- Enable or disable use of the shadow framebuffer layer. Default: off.
