.SH DESCRIPTION
|
|
.B nv
|
|
is an __xservername__ 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 higher depths.
|
|
|

.SH CONFIGURATION DETAILS
|
|
Please refer to __xconfigfile__(__filemansuffix__) for general configuration
|
|
details. This section only covers configuration details specific to this
|
|
driver.
|
|
.PP
|
|
The driver auto-detects the chipset type and the amount of video memory
|
|
present for all chips.
|
|
.PP
|
|
The following driver
|
|
.B Options
|
|
are supported:
|
|
.TP
|
|
.BI "Option \*qHWCursor\*q \*q" boolean \*q
|
|
Enable or disable the HW cursor. Default: on.
|
|
.TP
|
|
.BI "Option \*qNoAccel\*q \*q" boolean \*q
|
|
Disable or enable acceleration. Default: acceleration is enabled.
|
|
.TP
|
|
.BI "Option \*qUseFBDev\*q \*q" boolean \*q
|
|
Enable or disable use of on OS-specific fb interface (and is not supported
|
|
on all OSs). See fbdevhw(__drivermansuffix__) for further information.
|
|
Default: off.
|
|
.TP
|
|
.BI "Option \*qCrtcNumber\*q \*q" integer \*q
|
|
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".
|
|
Default: autodetected.
|
|
.TP
|
|
.BI "Option \*qFlatPanel\*q \*q" boolean \*q
|
|
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.
|
|
.TP
|
|
.BI "Option \*qFPDither\*q \*q" boolean \*q
|
|
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.
|
|
.TP
|
|
.BI "Option \*qRotate\*q \*qCW\*q"
|
|
.TP
|
|
.BI "Option \*qRotate\*q \*qCCW\*q"
|
|
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.
|
|
.TP
|
|
.BI "Option \*qShadowFB\*q \*q" boolean \*q
|
|
Enable or disable use of the shadow framebuffer layer. Default: off.
