.SH CONFIGURATION DETAILS
Please refer to XF86Config(__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 undefined.
.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).  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
others \-\- invalid
.TP 
.BI "Option \*qAGPFastWrite\*q \*q" boolean \*q
Enable AGP fast write.
.br
(used only when DRI is enabled)
.br
The default is
.B off.
.TP 
.BI "Option \*qForcePCIMode\*q \*q" boolean \*q
Force to use PCI GART for DRI acceleration.
.br
(used only when DRI is enabled)
.br
The default is
.B off.
.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 \*qCloneDisplay\*q \*q" integer \*q
.br 
This option is only used for dual\-head cards with only single 
screen section specified in the configuration file.

0      \-\- disable
.br 
1      \-\- auto\-detect (default)
.br 
2      \-\- force on
.br 
3      \-\- auto\-detect + 2nd head overlay
.br 
4      \-\- force on + 2nd head overlay
.br 
others \-\- auto\-detect

.B disable 
means only one CRTC is used for both heads.
.B auto\-detect 
means the secondary head will be driven by CRTC2 
if a monitor is detected there.
.B force on
means the secondary head will be driven by CRTC2
even no monitor is detected there.
.B 2nd-head overlay 
means the only hardware overlay will be placed to the secondary head.

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 prot 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
 
.TP 
.BI "Option \*qCloneMode\*q \*q" "string" \*q
Set the first mode for the secondary head.
It can be different from the modes used for the primary head. If you don't
have this line while clone is on, the modes specified for the primary head
will be used for the secondary head.
.TP 
.BI "Option \*qCloneHSync\*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
The default value is
.B undefined.
.TP 
.BI "Option \*qCloneVRefresh\*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
The default value is
.B undefined.
.TP 
.BI "Option \*qPanelOff\*q \*q" boolean \*q
Disable panel output. Only used when clone is enabled.
.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.
