.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 \*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

.br
The default is
.B auto detect.
.TP
.BI "Option \*qForcePCIMode\*q \*q" boolean \*q

This option is deprecated in favor of the
.BI BusType
option above and will be removed in the next release.
.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).

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 performence 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   \-\- Lapto 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 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

The default value is
.B undefined.
.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.
.br
For example, Option "CloneMode" "1024x768"
.br
The default value is
.B undefined.
.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
For example, Option "CloneHSync" "30.0-86.0"
.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
For example, Option "CloneVRefresh" "50.0-120.0"
.br
The default value is
.B undefined.
.TP
.BI "Option \*qOverlayOnCRTC2\*q \*q" boolean \*q
Force hardware overlay to clone head.
.br
The default value is
.B off.
.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. 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.

.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".
