求教：nvidia显卡xorg.conf里的Option
以前在公社里看见过，关于nolog以及透明支持、字体渲染的各个选项的解释以及命令，今天怎么也找不着了，哪位大哥给个链接吧！叩谢！！__________________________________________________________________________
Appendix D. X Config Options
__________________________________________________________________________
The following driver options are supported by the NVIDIA X driver. They may be
specified either in the Screen or Device sections of the X config file.
X Config Options
Option "NvAGP" "integer"
Configure AGP support. Integer argument can be one of:
Value Behavior
----------------------------- -----------------------------
0 disable agp
1 use NVIDIA's internal AGP
support, if possible
2 use AGPGART, if possible
3 use any agp support (try
AGPGART, then NVIDIA's AGP)
Please note that NVIDIA's internal AGP support cannot work if AGPGART
is either statically compiled into your kernel or is built as a
module, but loaded into your kernel (some distributions load AGPGART
into the kernel at boot up). Default: 3 (the default was 1 until after
1.0-1251).
Option "NoLogo" "boolean"
Disable drawing of the NVIDIA logo splash screen at X startup.
Default: the logo is drawn.
Option "RenderAccel" "boolean"
Enable or disable hardware acceleration of the RENDER extension. THIS
OPTION IS EXPERIMENTAL. ENABLE IT AT YOUR OWN RISK. There is no
correctness test suite for the RENDER extension so NVIDIA can not
verify that RENDER acceleration works correctly. Default: hardware
acceleration of the RENDER extension is disabled.
Option "NoRenderExtension" "boolean"
Disable the RENDER extension. Other than recompiling it, the X server
does not seem to have another way of disabling this. Fortunately, we
can control this from the driver so we export this option. This is
useful in depth 8 where RENDER would normally steal most of the
default colormap. Default: RENDER is offered when possible.
Option "UBB" "boolean"
Enable or disable Unified Back Buffer on any Quadro based GPUs
(Quadro4 NVS excluded); please see Appendix M for a description of
UBB. This option has no affect on non-Quadro chipsets. Default: UBB is
on for Quadro chipsets.
Option "NoFlip" "boolean"
Disable OpenGL flipping; please see Appendix K for a description.
Default: OpenGL will swap by flipping when possible.
Option "DigitalVibrance" "integer"
Enables Digital Vibrance Control. The range of valid values are 0
through 255. This feature is not available on products older than
GeForce2. Default: 0.
Option "Dac8Bit" "boolean"
Most Quadro parts by default use a 10 bit color look up table (LUT) by
default; setting this option to TRUE forces these graphics chips to
use an 8 bit (LUT). Default: a 10 bit LUT is used, when available.
Option "Overlay" "boolean"
Enables RGB workstation overlay visuals. This is only supported on
Quadro4 and Quadro FX chips (Quadro4 NVS excluded) in depth 24. This
option causes the server to advertise the SERVER_OVERLAY_VISUALS root
window property and GLX will report single and double buffered,
Z-buffered 16 bit overlay visuals. The transparency key is pixel
0x0000 (hex). There is no gamma correction support in the overlay
plane. This feature requires XFree86 version 4.1.0 or newer, or the
Xorg X server. NV17/18 based Quadros (i.e. 500/550 XGL) have
additional restrictions, namely, overlays are not supported in
TwinView mode or with virtual desktops larger than 2046x2047 in any
dimension (eg. it will not work in 2048x1536 modes). Quadro 7xx/9xx
and Quadro FX will offer overlay visuals in these modes (TwinView, or
virtual desktops larger than 2046x2047), but the overlay will be
emulated with a substantial performance penalty. RGB workstation
overlays are not supported when the Composite extension is enabled.
Default: off.
Option "CIOverlay" "boolean"
Enables Color Index workstation overlay visuals with identical
restrictions to Option "Overlay" above. The server will offer visuals
both with and without a transparency key. These are depth 8
PseudoColor visuals. Enabling Color Index overlays on X servers older
than XFree86 4.3 will force the RENDER extension to be disabled due to
bugs in the RENDER extension in older X servers. Color Index
workstation overlays are not supported when the Composite extension is
enabled. Default: off.
Option "TransparentIndex" "integer"
When color index overlays are enabled, use this option to choose which
pixel is used for the transparent pixel in visuals featuring
transparent pixels. This value is clamped between 0 and 255 (Note:
some applications such as Alias's Maya require this to be zero in
order to work correctly). Default: 0.
Option "OverlayDefaultVisual" "boolean"
When overlays are used, this option sets the default visual to an
overlay visual thereby putting the root window in the overlay. This
option is not recommended for RGB overlays. Default: off.
Option "RandRRotation" "boolean"
Enable rotation support for the XRandR extension. This allows use of
the XRandR X server extension for configuring the screen orientation
through rotation. This feature is supported on GeForce2 or better
hardware using depth 24. This requires an Xorg X 6.8.1 or newer X
server. This feature does not work with hardware overlays, emulated
overlays will be used instead at a substantial performance penalty.
See Appendix U for details. Default: off.
Option "AllowDDCCI" "boolean"
Enables DDC/CI support in the NV-CONTROL X extension. DDC/CI is a
mechanism for communication between your computer and your display
device. This can be used to set the values normally controlled through
your display device's On Screen Display. Please see the DDC/CI
NV-CONTROL attributes in 'NVCtrl.h' and functions in 'NVCtrlLib.h' in
the 'nvidia-settings' source code. Default: DDC/CI is disabled.
Option "SWCursor" "boolean"
Enable or disable software rendering of the X cursor. Default: off.
Option "HWCursor" "boolean"
Enable or disable hardware rendering of the X cursor. Default: on.
Option "CursorShadow" "boolean"
Enable or disable use of a shadow with the hardware accelerated
cursor; this is a black translucent replica of your cursor shape at a
given offset from the real cursor. This option is only available on
GeForce2 or better hardware (ie everything but TNT/TNT2, GeForce 256,
GeForce DDR and Quadro). Default: no cursor shadow.
Option "CursorShadowAlpha" "integer"
The alpha value to use for the cursor shadow; only applicable if
CursorShadow is enabled. This value must be in the range [0, 255] -- 0
is completely transparent; 255 is completely opaque. Default: 64.
Option "CursorShadowXOffset" "integer"
The offset, in pixels, that the shadow image will be shifted to the
right from the real cursor image; only applicable if CursorShadow is
enabled. This value must be in the range [0, 32]. Default: 4.
Option "CursorShadowYOffset" "integer"
The offset, in pixels, that the shadow image will be shifted down from
the real cursor image; only applicable if CursorShadow is enabled.
This value must be in the range [0, 32]. Default: 2.
Option "ConnectedMonitor" "string"
Allows you to override what the NVIDIA kernel module detects is
connected to your video card. This may be useful, for example, if you
use a KVM (keyboard, video, mouse) switch and you are switched away
when X is started. In such a situation, the NVIDIA kernel module
cannot detect what display devices are connected, and the NVIDIA X
driver assumes you have a single CRT.
Valid values for this option are "CRT" (cathode ray tube), "DFP"
(digital flat panel), or "TV" (television); if using TwinView, this
option may be a comma-separated list of display devices; e.g.: "CRT,
CRT" or "CRT, DFP".
NOTE: anything attached to a 15 pin VGA connector is regarded by the
driver as a CRT. "DFP" should only be used to refer to flatpanels
connected via a DVI port.
Default: string is NULL.
Option "UseEdidFreqs" "boolean"
This option causes the X server to use the HorizSync and VertRefresh
ranges given in a display device's EDID, if any. EDID provided range
information will override the HorizSync and VertRefresh ranges
specified in the Monitor section. If a display device does not provide
an EDID, or the EDID does not specify an hsync or vrefresh range, then
the X server will default to the HorizSync and VertRefresh ranges
specified in the Monitor section.
Option "IgnoreEDID" "boolean"
Disable probing of EDID (Extended Display Identification Data) from
your monitor. Requested modes are compared against values gotten from
your monitor EDIDs (if any) during mode validation. Some monitors are
known to lie about their own capabilities. Ignoring the values that
the monitor gives may help get a certain mode validated. On the other
hand, this may be dangerous if you do not know what you are doing.
Default: Use EDIDs.
Option "NoDDC" "boolean"
Synonym for "IgnoreEDID"
Option "FlatPanelProperties" "string"
Requests particular properties of any connected flat panels as a
comma-separated list of property=value pairs. Currently, the only two
available properties are 'Scaling' and 'Dithering'. The possible
values for 'Scaling' are: 'default' (the driver will use whatever
scaling state is current), 'native' (the driver will use the flat
panel's scaler, if it has one), 'scaled' (the driver will use the
NVIDIA scaler, if possible), 'centered' (the driver will center the
image, if possible), and 'aspect-scaled' (the driver will scale with
the NVIDIA scaler, but keep the aspect ratio correct). The possible
values for 'Dithering' are: 'default' (the driver will decide when to
dither), 'enabled' (the driver will always dither when possible), and
'disabled' (the driver will never dither). If any property is not
specified, it's value shall be 'default'. An example properties string
might look like:
"Scaling = centered, Dithering = enabled"
Option "UseInt10Module" "boolean"
Enable use of the X Int10 module to soft-boot all secondary cards,
rather than POSTing the cards through the NVIDIA kernel module.
Default: off (POSTing is done through the NVIDIA kernel module).
Option "TwinView" "boolean"
Enable or disable TwinView. Please see Appendix G for details.
Default: TwinView is disabled.
Option "TwinViewOrientation" "string"
Controls the relationship between the two display devices when using
TwinView. Takes one of the following values: "RightOf" "LeftOf"
"Above" "Below" "Clone". Please see Appendix G for details. Default:
string is NULL.
Option "SecondMonitorHorizSync" "range(s)"
This option is like the HorizSync entry in the Monitor section, but is
for the second monitor when using TwinView. Please see Appendix G for
details. Default: none.
Option "SecondMonitorVertRefresh" "range(s)"
This option is like the VertRefresh entry in the Monitor section, but
is for the second monitor when using TwinView. Please see Appendix G
for details. Default: none.
Option "MetaModes" "string"
This option describes the combination of modes to use on each monitor
when using TwinView. Please see Appendix G for details. Default:
string is NULL.
Option "NoTwinViewXineramaInfo" "boolean"
When in TwinView, the NVIDIA X driver normally provides a Xinerama
extension that X clients (such as window managers) can use to discover
the current TwinView configuration. Some window mangers get confused
by this information, so this option is provided to disable this
behavior. Default: TwinView Xinerama information is provided.
Option "TVStandard" "string"
Please see Appendix H for details on configuring TV-out.
Option "TVOutFormat" "string"
Please see Appendix H for details on configuring TV-out.
Option "TVOverScan" "Decimal value in the range 0.0 to 1.0"
Valid values are in the range 0.0 through 1.0; Please see Appendix H
for details on configuring TV-out.
Option "Stereo" "integer"
Enable offering of quad-buffered stereo visuals on Quadro. Integer
indicates the type of stereo glasses being used:
Value Equipment
----------------------------- -----------------------------
1 DDC glasses. The sync signal
is sent to the glasses via
the DDC signal to the
monitor. These usually
involve a passthrough cable
between the monitor and video
card.
2 "Blueline" glasses. These
usually involve a passthrough
cable between the monitor and
video card. The glasses know
which eye to display based on
the length of a blue line
visible at the bottom of the
screen. When in this mode,
the root window dimensions
are one pixel shorter in the
Y dimension than requested.
This mode does not work with
virtual root window sizes
larger than the visible root
window size (desktop
panning).
3 Onboard stereo support. This
is usually only found on
professional cards. The
glasses connect via a DIN
connector on the back of the
video card.
4 TwinView clone mode stereo
(aka "passive" stereo). On
video cards that support
TwinView, the left eye is
displayed on the first
display, and the right eye is
displayed on the second
display. This is normally
used in conjuction with
special projectors to produce
2 polarized images which are
then viewed with polarized
glasses. To use this stereo
mode, you must also configure
TwinView in clone mode with
the same resolution, panning
offset, and panning domains
on each display.
Stereo is only available on Quadro cards. Stereo options 1, 2, and 3
(aka "active" stereo) may be used with TwinView if all modes within
each metamode have identical timing values. Please see Appendix J for
suggestions on making sure the modes within your metamodes are
identical. The identical modeline requirement is not necessary for
Stereo option 4 ("passive" stereo). Currently, stereo operation may be
"quirky" on the original Quadro (NV10) chip and left-right flipping
may be erratic. We are trying to resolve this issue for a future
release. Default: Stereo is not enabled.
UBB must be enabled when stereo is enabled (this is the default
behavior).
Stereo options 1, 2, and 3 (aka "active" stereo) are not supported on
digital flat panels.
Option "AllowDFPStereo" "boolean"
By default, the NVIDIA X driver performs a check which disables active
stereo (stereo options 1, 2, and 3) if the X screen is driving a DFP.
The "AllowDFPStereo" option bypasses this check.
Option "NoBandWidthTest" "boolean"
As part of mode validation, the X driver tests if a given mode fits
within the hardware's memory bandwidth constraints. This option
disables this test. Default: the memory bandwidth test is performed.
Option "IgnoreDisplayDevices" "string"
This option tells the NVIDIA kernel module to completely ignore the
indicated classes of display devices when checking what display
devices are connected. You may specify a comma-separated list
containing any of "CRT", "DFP", and "TV". For example:
Option "IgnoreDisplayDevices" "DFP, TV"
will cause the NVIDIA driver to not attempt to detect if any
flatpanels or TVs are connected. This option is not normally
necessary; however, some video BIOSes contain incorrect information
about what display devices may be connected, or what i2c port should
be used for detection. These errors can cause long delays in starting
X. If you are experiencing such delays, you may be able to avoid this
by telling the NVIDIA driver to ignore display devices which you know
are not connected. NOTE: anything attached to a 15 pin VGA connector
is regarded by the driver as a CRT. "DFP" should only be used to refer
to flatpanels connected via a DVI port.
Option "MultisampleCompatibility" "boolean"
Enable or disable the use of separate front and back multisample
buffers. This will consume more memory but is necessary for correct
output when rendering to both the front and back buffers of a
multisample or FSAA drawable. This option is necessary for correct
operation of SoftImage XSI. Default: a singlemultisample buffer is
shared between the front and back buffers.
Option "NoPowerConnectorCheck" "boolean"
The NVIDIA X driver will abort X server initialization if it detects
that a GPU that requires an external power connector does not have an
external power connector plugged in. This option can be used to bypass
this test. Default: the power connector test is performed.
Option "XvmcUsesTextures" "boolean"
Forces XvMC to use the 3D engine for XvMCPutSurface requests rather
than the video overlay. Default: video overlay is used when available.
Option "AllowGLXWithComposite" "boolean"
Enables GLX even when the Composite X extension is loaded. ENABLE AT
YOUR OWN RISK. OpenGL applications will not display correctly in many
circumstances with this setting enabled. Default: GLX is disabled when
Composite is loaded.
Option "ExactModeTimingsDVI" "boolean"
Forces the initialization of the X server with the exact timings
specified in the ModeLine. Default: For DVI devices, the X server
inilializes with the closest mode in the EDID list.
Option "Coolbits" "integer"
Enables support in the NV-CONTROL X extension for manipulating GPU
clock settings. When this option is set to "1" the nvidia-settings
utility will contain a page labeled "Clock Frequencies" through which
clock settings can be manipulated. Coolbits is only available on
GeForce FX, Quadro FX, and newer GPUs.
WARNING: this may cause system damage and void warranties. This
utility can run your computer system out of the manufacturer's design
specifications, including, but not limited to: higher system voltages,
above normal temperatures, excessive frequencies, and changes to BIOS
that may corrupt the BIOS. Your computer's operating system may hang
and result in data loss or corrupted images. Depending on the
manufacturer of your computer system, the computer system, hardware
and software warranties may be voided, and you may not receive any
further manufacturer support. NVIDIA does not provide customer service
support for the Coolbits option. It is for these reasons that
absolutely no warranty or guarantee is either express or implied.
Before enabling and using, you should determine the suitability of the
utility for your intended use, and you shall assume all responsibility
in connection therewith.
Option "LoadKernelModule" "boolean"
By default, the NVIDIA Linux X driver module will attempt to load the
NVIDIA Linux kernel module. Set this option to "off" to disable
automatic loading of the NVIDIA kernel module by the NVIDIA X driver.

忘记说一下了：不同版本的驱动能用的option也不同，我上面贴的是7676的
最好的做法是，安装完驱动以后，退出到字符终端，然后 Xorg -configure 一下，这样在家目录下新生成的xorg.conf.new的device字段就会有你当前所有可用的option了
