|
|
.br
|
|
(when only one port is used, it will be treated as the primary regardless)
|
|
.br
|
|
.B Primary head:
|
|
.br
|
|
DVI port on DVI+VGA cards
|
|
.br
|
|
LCD output on laptops
|
|
.br
|
|
Internal TMDS port on DVI+DVI cards
|
|
.br
|
|
.B Secondary head:
|
|
.br
|
|
VGA port on DVI+VGA cards
|
|
.br
|
|
VGA port on laptops
|
|
.br
|
|
External TMDS port on DVI+DVI cards
|
|
|
|
The default value is
|
|
.B undefined.
|
|
.TP
|
|
.BI "Option \*qMergedFB\*q \*q" boolean \*q
|
|
This enables merged framebuffer mode. In this mode you have a single
|
|
shared framebuffer with two viewports looking into it. It is similar
|
|
to Xinerama, but has some advantages. It is faster than Xinerama, the
|
|
DRI works on both heads, and it supports clone modes.
|
|
.br
|
|
Merged framebuffer mode provides two linked viewports looking into a
|
|
single large shared framebuffer. The size of the framebuffer is
|
|
determined by the
|
|
.B Virtual
|
|
keyword defined on the
|
|
.B Screen
|
|
section of your __xconfigfile__ file. It works just like regular virtual
|
|
desktop except you have two viewports looking into it instead of one.
|
|
.br
|
|
For example, if you wanted a desktop composed of two 1024x768 viewports
|
|
looking into a single desktop you would create a virtual desktop of
|
|
2048x768 (left/right) or 1024x1536 (above/below), e.g.,
|
|
.br
|
|
.B Virtual 2048 768
|
|
or
|
|
.B Virtual 1024 1536
|
|
.br
|
|
The virtual desktop can be larger than larger than the size of the viewports
|
|
looking into it. In this case the linked viewports will scroll around in the
|
|
virtual desktop. Viewports with different sizes are also supported (e.g., one
|
|
that is 1024x768 and one that is 640x480). In this case the smaller viewport
|
|
will scroll relative to the larger one such that none of the virtual desktop
|
|
is inaccessible. If you do not define a virtual desktop the driver will create
|
|
one based on the orientation of the heads and size of the largest defined mode in
|
|
the display section that is supported on each head.
|
|
.br
|
|
The relation of the viewports in specified by the
|
|
.B CRT2Position
|
|
Option. The options are
|
|
.B Clone
|
|
,
|
|
.B LeftOf
|
|
,
|
|
.B RightOf
|
|
,
|
|
.B Above
|
|
, and
|
|
.B Below.
|
|
MergedFB is enabled by default if a monitor is detected on each output. If
|
|
no position is given it defaults to clone mode (the old clone options are now
|
|
deprecated, also, the option OverlayOnCRTC2 has been replaced by the Xv
|
|
attribute XV_SWITCHCRT; the overlay can be switched to CRT1 or CRT2 on the fly
|
|
in clone mode).
|
|
.br
|
|
The maximum framebuffer size that the 2D acceleration engine can handle is
|
|
8192x8192. The maximum framebuffer size that the 3D engine can handle is
|
|
2048x2048.
|
|
.br
|
|
.B Note:
|
|
Page flipping does not work well in certain configurations with MergedFB. If you
|
|
see rendering errors or other strange behavior, disable page flipping. Also MergedFB
|
|
is not compatible with the
|
|
.B UseFBDev
|
|
option.
|
|
.br
|
|
The default value is
|
|
.B undefined.
|
|
.TP
|
|
.BI "Option \*qCRT2HSync\*q \*q" "string" \*q
|
|
Set the horizontal sync range for the secondary monitor.
|
|
It is not required if a DDC\-capable monitor is connected.
|
|
.br
|
|
For example, Option "CRT2HSync" "30.0-86.0"
|
|
.br
|
|
The default value is
|
|
.B undefined.
|
|
.TP
|
|
.BI "Option \*qCRT2VRefresh\*q \*q" "string" \*q
|
|
Set the vertical refresh range for the secondary monitor.
|
|
It is not required if a DDC\-capable monitor is connected.
|
|
.br
|
|
For example, Option "CRT2VRefresh" "50.0-120.0"
|
|
.br
|
|
The default value is
|
|
.B undefined.
|
|
.TP
|
|
.BI "Option \*qCRT2Position\*q \*q" "string" \*q
|
|
Set the relationship of CRT2 relative to CRT1. Valid options are:
|
|
.B Clone
|
|
,
|
|
.B LeftOf
|
|
,
|
|
.B RightOf
|
|
,
|
|
.B Above
|
|
, and
|
|
.B Below
|
|
.
|
|
.br
|
|
For example, Option "CRT2Position" "RightOf"
|
|
.br
|
|
This option also supports an offset. This is most useful when
|
|
.B MergedNonRectangular
|
|
is enabled. For example if you want CRT2 to be offset 100 pixels down from
|
|
the start of CRT1, you'd type:
|
|
.br
|
|
Option "CRT2Position" "LeftOf 100"
|
|
.br
|
|
The offset is vertical for LeftOf and RightOf and horizontal for Above and
|
|
Below. Offsets can be positive or negative.
|
|
.br
|
|
The default value is
|
|
.B Clone.
|
|
.TP
|
|
.BI "Option \*qMetaModes\*q \*q" "string" \*q
|
|
MetaModes are mode combinations for CRT1 and CRT2. If you are using merged
|
|
frame buffer mode and want to change modes (CTRL-ALT-+/-), these define which
|
|
modes will be switched to on CRT1 and CRT2. The MetaModes are defined as
|
|
CRT1Mode-CRT2Mode (800x600-1024x768). Modes listed individually (800x600)
|
|
define clone modes, that way you can mix clone modes with non-clone modes.
|
|
Also some programs require "standard" modes. If you want to add clone modes
|
|
of different refreshes or sizes to the mix, they are defined as CRT1Mode+CRT2Mode
|
|
(800x600+1024x768).
|
|
.br
|
|
Note: Any mode you use in the MetaModes must be defined in the
|
|
.B Screen
|
|
section of your __xconfigfile__ file. Modes not defined there will be ignored when
|
|
the MetaModes are parsed since the driver uses them to make sure the monitors can
|
|
handle those modes. If you do not define a MetaMode the driver will create
|
|
one based on the orientation of the heads and size of the largest defined mode in
|
|
the display section that is supported on each head.
|
|
.br
|
|
.B Modes "1024x768" "800x600" "640x480"
|
|
.br
|
|
For example, Option "MetaModes" "1024x768-1024x768 800x600-1024x768 640x480-800x600 800x600"
|
|
.br
|
|
The default value is
|
|
.B undefined.
|
|
.TP
|
|
.BI "Option \*qMergedXinerama\*q \*q" boolean \*q
|
|
Since merged framebuffer mode does not use Xinerama, apps are not able to intelligently
|
|
place windows. Merged framebuffer mode provides its own pseudo-Xinerama. This allows
|
|
Xinerama compliant applications to place windows appropriately. There are some caveats.
|
|
Since merged framebuffer mode is able to change relative screen sizes and orientations on
|
|
the fly, as well has having overlapping viewports, pseudo-Xinerama, might not always
|
|
provide the right hints. Also many Xinerama compliant applications only query Xinerama
|
|
once at startup; if the information changes, they may not be aware of the change. If
|
|
you are already using Xinerama (e.g., a single head card and a dualhead card providing
|
|
three heads), pseudo-Xinerama will be disabled.
|
|
.br
|
|
This option allows you turn off the driver provided pseudo-Xinerama extension.
|
|
.br
|
|
The default value is
|
|
.B TRUE.
|
|
.TP
|
|
.BI "Option \*qMergedXineramaCRT2IsScreen0\*q \*q" boolean \*q
|
|
By default the pseudo-Xinerama provided by the driver makes the left-most or bottom
|
|
head Xinerama screen 0. Certain Xinerama-aware applications do special things with
|
|
screen 0. To change that behavior, use this option.
|
|
.br
|
|
The default value is
|
|
.B undefined.
|
|
.TP
|
|
.BI "Option \*qMergedDPI\*q \*q" "string" \*q
|
|
The driver will attempt to figure out an appropriate DPI based on the DDC information
|
|
and the orientation of the heads when in merged framebuffer mode. If this value does
|
|
not suit you, you can manually set the DPI using this option.
|
|
.br
|
|
For example, Option "MergedDPI" "100 100"
|
|
.br
|
|
The default value is
|
|
.B undefined.
|
|
.TP
|
|
.BI "Option \*qMergedNonRectangular\*q \*q" boolean \*q
|
|
If you are using MergedFB with two modes of different sizes, turn this option on to
|
|
keep the smaller head from scrolling within the larger virtual desktop and to keep
|
|
the mouse from moving into that area. Applications that are not Xinerama aware can
|
|
potentially end up stranded in this area.
|
|
.br
|
|
The default value is
|
|
.B FALSE.
|
|
.TP
|
|
.BI "Option \*qColorTiling\*q \*q" "boolean" \*q
|
|
Frame buffer can be addressed either in linear or tiled mode. Tiled mode can provide
|
|
significant performance benefits with 3D applications, for 2D it shouldn't matter
|
|
much. Tiling will be disabled if the virtual x resolution exceeds 2048 (3968 for R300
|
|
and above), if option
|
|
.B UseFBDev
|
|
is used, or (if DRI is enabled) the drm module is too old.
|
|
.br
|
|
If this option is enabled, a new dri driver is required for direct rendering too.
|
|
.br
|
|
Color tiling will be automatically disabled in interlaced or doublescan screen modes.
|
|
.br
|
|
The default value is
|
|
.B on.
|
|
.TP
|
|
.BI "Option \*qIgnoreEDID\*q \*q" boolean \*q
|
|
Do not use EDID data for mode validation, but DDC is still used
|
|
for monitor detection. This is different from NoDDC option.
|
|
.br
|
|
The default value is
|
|
.B off.
|
|
.TP
|
|
.BI "Option \*qPanelSize\*q \*q" "string" \*q
|
|
Should only be used when driver cannot detect the correct panel size.
|
|
Apply to both desktop (TMDS) and laptop (LVDS) digital panels.
|
|
When a valid panel size is specified, the timings collected from
|
|
DDC and BIOS will not be used. If you have a panel with timings
|
|
different from that of a standard VESA mode, you have to provide
|
|
this information through the Modeline.
|
|
.br
|
|
For example, Option "PanelSize" "1400x1050"
|
|
.br
|
|
The default value is
|
|
.B none.
|
|
.TP
|
|
.BI "Option \*qPanelOff\*q \*q" boolean \*q
|
|
Disable panel output.
|
|
.br
|
|
The default value is
|
|
.B off.
|
|
.TP
|
|
.BI "Option \*qEnablePageFlip\*q \*q" boolean \*q
|
|
Enable page flipping for 3D acceleration. This will increase performance
|
|
but not work correctly in some rare cases, hence the default is
|
|
.B off.
|
|
.TP
|
|
.BI "Option \*qForceMinDotClock\*q \*q" frequency \*q
|
|
Override minimum dot clock. Some Radeon BIOSes report a minimum dot
|
|
clock unsuitable (too high) for use with television sets even when they
|
|
actually can produce lower dot clocks. If this is the case you can

override the value here.
|
|
.B Note that using this option may damage your hardware.
|
|
You have been warned. The
|
|
.B frequency
|
|
parameter may be specified as a float value with standard suffixes like
|
|
"k", "kHz", "M", "MHz".
|
|
.TP
|
|
.BI "Option \*qRenderAccel\*q \*q" boolean \*q
|
|
Enables or disables hardware Render acceleration. This driver does not
|
|
support component alpha (subpixel) rendering. It is only supported on
|
|
Radeon series up to and including 9200 (9500/9700 and newer
|
|
unsupported). The default is to
|
|
.B enable
|
|
Render acceleration.
|
|
.TP
|
|
.BI "Option \*qAccelMethod\*q \*q" "string" \*q
|
|
Chooses between available acceleration architectures. Valid options are
|
|
.B XAA
|
|
and
|
|
.B EXA.
|
|
XAA is the traditional acceleration architecture and support for it is very
|
|
stable. EXA is a newer acceleration architecture with better performance for
|
|
the Render and Composite extensions, but the rendering code for it is newer and
|
|
possibly unstable. The default is
|
|
.B XAA.
|
|
.TP
|
|
.BI "Option \*qAccelDFS\*q \*q" boolean \*q
|
|
Use or don't use accelerated EXA DownloadFromScreen hook when possible (only
|
|
when Direct Rendering is enabled, e.g.).
|
|
Default:
|
|
.B off
|
|
with AGP due to issues with GPU->host transfers with some AGP bridges,
|
|
.B on
|
|
otherwise.
|
|
.TP
|
|
.BI "Option \*qFBTexPercent\*q \*q" integer \*q
|
|
Amount of video RAM to reserve for OpenGL textures, in percent. With EXA, the
|
|
remainder of video RAM is reserved for EXA offscreen management. Specifying 0
|
|
results in all offscreen video RAM being reserved for EXA and only GART memory
|
|
being available for OpenGL textures. This may improve EXA performance, but
|
|
beware that it may cause problems with OpenGL drivers from Mesa versions older
|
|
than 6.4. With XAA, specifiying lower percentage than what gets reserved without
|
|
this option has no effect, but the driver tries to increase the video RAM
|
|
reserved for textures to the amount specified roughly.
|
|
Default:
|
|
.B 50.
|
|
.TP
|
|
.BI "Option \*qDepthBits\*q \*q" integer \*q
|
|
Precision in bits per pixel of the shared depth buffer used for 3D acceleration.
|
|
Valid values are 16 and 24. When this is 24, there will also be a hardware
|
|
accelerated stencil buffer, but the combined depth/stencil buffer will take up
|
|
twice as much video RAM as when it's 16.
|
|
Default:
|
|
.B The same as the screen depth.
|
|
.TP
|
|
.BI "Option \*qDMAForXv\*q \*q" boolean \*q
|
|
Try or don't try to use DMA for Xv image transfers. This will reduce CPU
|
|
usage when playing big videos like DVDs, but may cause instabilities.
|
|
Default:
|
|
.B on.
|
|
.TP
|
|
.BI "Option \*qSubPixelOrder\*q \*q" "string" \*q
|
|
Force subpixel order to specified order.
|
|
Subpixel order is used for subpixel decimation on flat panels.
|
|
.br
|
|
NONE \-\- No subpixel (CRT like displays)
|
|
.br
|
|
RGB \-\- in horizontal RGB order (most flat panels)
|
|
.br
|
|
BGR \-\- in horizontal BGR order (some flat panels)
|
|
|
|
.br
|
|
This option is intended to be used in following cases:
|
|
.br
|
|
1. The default subpixel order is incorrect for your panel.
|
|
.br
|
|
2. Enable subpixel decimation on analog panels.
|
|
.br
|
|
3. Adjust to one display type in dual-head clone mode setup.
|
|
.br
|
|
4. Get better performance with Render acceleration on
|
|
digital panels (use NONE setting).
|
|
.br
|
|
The default is
|
|
.B NONE
|
|
for CRT,
|
|
.B RGB
|
|
for digital panels
|
|
.TP
|
|
.BI "Option \*qDynamicClocks\*q \*q" boolean \*q
|
|
Enable dynamic clock scaling. The on-chip clocks will scale dynamically
|
|
based on usage. This can help reduce heat and increase battery
|
|
life by reducing power usage. Some users report reduced 3D performance
|
|
with this enabled. The default is
|
|
.B off.
|
|
.TP
|
|
.BI "Option \*qBIOSHotkeys\*q \*q" boolean \*q
|
|
Enable BIOS hotkey output switching. This allows the BIOS to toggle outputs
|
|
using hotkeys (e.g., fn-f7, etc.). Since the driver does not support ACPI,
|
|
there is no way to validate modes on an output switch and the BIOS can
|
|
potentially change things behind the driver's back. The default is
|
|
.B off.
|
|
.TP
|
|
.BI "Option \*qVGAAccess\*q \*q" boolean \*q
|
|
Tell the driver if it can do legacy VGA IOs to the card. This is
|
|
necessary for properly resuming consoles when in VGA text mode, but
|
|
shouldn't be if the console is using radeonfb or some other graphic
|
|
mode driver. Some platforms like PowerPC have issues with those, and they aren't
|
|
necessary unless you have a real text mode in console. The default is
|
|
.B off
|
|
on PowerPC and
|
|
.B on
|
|
on other architectures.
|
|
.TP
|
|
.BI "Option \*qReverseDDC\*q \*q" boolean \*q
|
|
When BIOS connector informations aren't available, use this option to
|
|
reverse the mapping of the 2 main DDC ports. Use this if the X serve
|
|
obviously detects the wrong display for each connector. This is
|
|
typically needed on the Radeon 9600 cards bundled with Apple G5s. The
|
|
default is
|
|
.B off.
|
|
.TP
|
|
.BI "Option \*qLVDSProbePLL\*q \*q" boolean \*q
|
|
When BIOS panel informations aren't available (like on PowerBooks), it
|
|
may still be necessary to use the firmware provided PLL values for the
|
|
panel or flickering will happen. This option will force probing of
|
|
the current value programmed in the chip when X is launched in that
|
|
case. This is only useful for LVDS panels (laptop internal panels).
|
|
The default is
|
|
.B on.
