|
||
|
|
and newer models. All visuals are supported in depth 8. TrueColor and
|
||
|
|
DirectColor visuals are supported in the other depths.

|
|
Please refer to __xconfigfile__(__filemansuffix__) for general configuration
|
||
|
|
details. This section only covers configuration details specific to this
|
||
|
|
driver.

The following driver
|
||
|
|
.B Options
|
||
|
|
are supported
|
||
|
|
.TP
|
||
|
|
.BI "Option \*qNoAccel\*q \*q" boolean \*q
|
||
|
|
Disable or enable acceleration. Default: acceleration is enabled.
|
||
|
|
.TP
|
||
|
|
.BI "Option \*qSWCursor\*q \*q" boolean \*q
|
||
|
|
Disable or enable software cursor. Default: software cursor is disable
|
||
|
|
and a hardware cursor is used.
|
||
|
|
.TP
|
||
|
|
.BI "Option \*qPCIBurst\*q \*q" boolean \*q
|
||
|
|
Disable or enable PCI burst modes. Default: enabled.
|
||
|
|
.TP
|
||
|
|
.BI "Option \*qRotate\*q \*qCW\*q"
|
||
|
|
.TP
|
||
|
|
.BI "Option \*qRotate\*q \*qCCW\*q"
|
||
|
|
Rotate the display clockwise or counterclockwise. This mode is unaccelerated.
|
||
|
|
Default: no rotation.
|
||
|
|
.TP
|
||
|
|
.BI "Option \*qShadowFB\*q \*q" boolean \*q
|
||
|
|
Enable or disable use of the shadow framebuffer layer. Default: off.
|
||
|
|
.TP
|
||
|
|
.BI "Option \*qOverlayMem\*q \*q" integer \*q
|
||
|
|
Reserve the given amount of memory (in bytes) for the XVideo overlay. On
|
||
|
|
boards with limited memory, display of large XVideo buffers might fail due
|
||
|
|
to insufficient available memory. Using this option solves the problem at
|
||
|
|
the expense of reducing the memory available for other operations. For
|
||
|
|
full\-resolution DVDs, 829440 bytes (720x576x2) are necessary.
