|
|
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 for pre-G80 hardware:
|
|
.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 an 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
|
|
Many graphics cards with NVIDIA chips 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 \*qDualhead\*q \*q" boolean \*q
|
|
Enables simple VBE-based dual head mode.
|
|
This sets the same resolution on both outputs and lays them out side-by-side.
|
|
The screens will be panned together as one big metamode if the virtual desktop is larger than both screens combined.
|
|
.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 work only if it was POSTed by the BIOS,
|
|
that is, the computer
|
|
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: autodetected.
|
|
.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.
|
|
Default: off.
|
|
.TP
|
|
.BI "Option \*qFPScale\*q \*q" boolean \*q
|
|
Supported only on GeForce4 and newer chips, this option
|
|
tells to the driver to scale lower resolutions up to the flat panel's native
|
|
resolution. Default: on.
|
|
.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 "CW" or
|
|
Rotate "CCW" options are used.
|
|
.TP
|
|
.BI "Option \*qRotate\*q \*qRandR\*q"
|
|
Enable rotation of the screen using the Resize and Rotate extension.
|
|
This mode is unaccelerated.
|
|
Default: no rotation support.
|
|
.TP
|
|
.BI "Option \*qShadowFB\*q \*q" boolean \*q
|
|
Enable or disable use of the shadow framebuffer layer. Default: off.
|
|
.
|
|
.\" ******************** begin G80 section ********************
|
|
.PP
|
|
The following driver
|
|
.B Options
|
|
are available for G80 and higher:
|
|
.TP
|
|
.BI "Option \*qHWCursor\*q \*q" boolean \*q
|
|
Enable or disable the hardware cursor. Default: on.
|
|
.TP
|
|
.BI "Option \*qNoAccel\*q \*q" boolean \*q
|
|
Disable or enable acceleration. Default: acceleration is enabled.
|
|
.TP
|
|
.BI "Option \*qAccelMethod\*q \*q" string \*q
|
|
Choose acceleration architecture, either \*qXAA\*q or \*qEXA\*q.
|
|
XAA is the old but stable architecture.
|
|
EXA is newer and supports resizing the desktop larger than it started out with RandR 1.2.
|
|
If you choose to use EXA, you might also consider setting
|
|
.B Option \*qMigrationHeuristic\*q \*qgreedy\*q
|
|
to improve performance.
|
|
Default: XAA.
|
|
.TP
|
|
.BI "Option \*qFPDither\*q \*q" boolean \*q
|
|
Enable or disable flat panel dithering by default.
|
|
Dithering can also be enabled or disabled using the RandR 1.2 \*qdither\*q output property.
|
|
Default: off.
|
|
.TP
|
|
.BI "Option \*qAllowDualLinkModes\*q \*q" boolean \*q
|
|
Allow validation of dual-link DVI modes.
|
|
Not all GPUs are configured at boot time to be able to handle dual-link modes, so they are disabled by default.
|
|
.
|
|
.\" RandR 1.2
|
|
.PP
|
|
The following RandR 1.2 properties are available for flat panels on G80 and higher GPUs:
|
|
.TP
|
|
.B dither
|
|
Enable or disable flat panel dithering.
|
|
Valid values:
|
|
.BR 0 " (off), " 1 " (on)."
|
|
.TP
|
|
.B scale
|
|
Control how the image is scaled to fit the flat panel.
|
|
Note that some flat panels perform their own scaling, overriding this option.
|
|
.RB \*q off \*q
|
|
is not valid for laptop flat panels (LVDS).
|
|
Valid values:
|
|
.RB \*q off "\*q, \*q" aspect "\*q, \*q" fill "\*q, and \*q" center \*q.
|
|
Default:
|
|
.RB \*q aspect \*q.
