.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 all device information necessary to initialize
the card.  However, if you have problems with auto\-detection, you can
specify:
.PP
.RS 4
VideoRam \- in kilobytes
.br
MemBase  \- physical address of the linear framebuffer
.br
IOBase   \- physical address of the MMIO registers
.br
ChipID   \- PCI DEVICE ID
.RE
.PP
In addition, the following driver
.B Options
are supported:
.TP
.BI "Option \*qSWcursor\*q \*q" boolean \*q
Selects software cursor.  The default is
.B off.
.TP
.BI "Option \*qNoAccel\*q \*q" boolean \*q
Enables or disables all hardware acceleration.
.br
The default is to
.B enable
hardware acceleration.
.TP
.BI "Option \*qDac6Bit\*q \*q" boolean \*q
Enables or disables the use of 6 bits per color component when in 8 bpp
mode (emulates VGA mode).  By default, all 8 bits per color component
are used.
.br
The default is
.B off.
.TP
.BI "Option \*qVideoKey\*q \*q" integer \*q
This overrides the default pixel value for the YUV video overlay key.
.br
The default value is
.B 0x1E.
.TP
.BI "Option \*qUseFBDev\*q \*q" boolean \*q
Enable or disable use of an OS\-specific framebuffer device interface
(which is not supported on all OSs).  MergedFB does not work when this
option is in use.  See fbdevhw(__drivermansuffix__) for further information. 
.br
The default is
.B off.
.TP
.BI "Option \*qAGPMode\*q \*q" integer \*q
Set AGP data transfer rate.
(used only when DRI is enabled)
.br
1      \-\- x1 (default)
.br
2      \-\- x2
.br
4      \-\- x4
.br
8      \-\- x8
.br
others \-\- invalid
.TP
.BI "Option \*qAGPFastWrite\*q \*q" boolean \*q
Enable AGP fast write.  Enabling this option is frequently the cause of
instability. Used only when the DRI is enabled.
.br
The default is
.B off.
.TP
.BI "Option \*qBusType\*q \*q" string \*q
Used to replace previous ForcePCIMode option.
Should only be used when driver's bus detection is incorrect
or you want to force a AGP card to PCI mode. Should NEVER force
a PCI card to AGP bus.
.br
PCI    \-\- PCI bus
.br
AGP    \-\- AGP bus
.br
PCIE   \-\- PCI Express (falls back to PCI at present)
.br
(used only when DRI is enabled)
.br
The default is
.B auto detect.
.TP 
.BI "Option \*qDDCMode\*q \*q" boolean \*q
Force to use the modes queried from the connected monitor.
.br
The default is
.B off.
.TP
.BI "Option \*qDisplayPriority\*q \*q" string \*q
.br
Used to prevent flickering or tearing problem caused by display buffer underflow.
.br
AUTO   \-\- Driver calculated (default).
.br
BIOS   \-\- Remain unchanged from BIOS setting.
          Use this if the calculation is not correct
          for your card.
.br
HIGH   \-\- Force to the highest priority.
          Use this if you have problem with above options.
          This may affect performance slightly.
.br
The default value is
.B AUTO.
.TP
.BI "Option \*qMonitorLayout\*q \*q" string \*q
.br
This option is used to overwrite the detected monitor types.
This is only required when driver makes a false detection.
The possible monitor types are:
.br
NONE   \-\- Not connected
.br
CRT    \-\- Analog CRT monitor
.br
TMDS   \-\- Desktop flat panel
.br 
LVDS   \-\- Laptop flat panel
.br
This option can be used in following format:
.br
Option "MonitorLayout" "[type on primary], [type on secondary]"
.br
For example, Option "MonitorLayout" "CRT, TMDS"

Primary/Secondary head for dual\-head cards:
.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.
