These cards have been ported but need further testing and
may not work.
CONFIGURATION DETAILS
Please refer to xorg.conf(5) for general configuration details. This
section only covers configuration details specific to this driver.
The following driver Options are supported:
Option "SWCursor" "boolean"
Enable or disable the SW cursor. Default: off.
Option "NoAccel" "boolean"
Disable or enable acceleration. Default: acceleration is
enabled.
Option "PciRetry" "boolean"
Enable or disable PCI retries. Default: off.
Option "CyberShadow" "boolean"
For Cyber chipsets only, turn off shadow registers. If you only
see a partial display - this may be the option for you. Default:
on.
Option "CyberStretch" "boolean"
For Cyber chipsets only, turn on stretching. When the resolution
is lower than the LCD's screen, this option will stretch the
graphics mode to fill the entire LCD. Default: off.
Option "ShadowFB" "boolean"
Enable or disable use of the shadow framebuffer layer. Default:
off.
Option "VideoKey" "integer"
This sets the default pixel value for the YUV video overlay key.
Default: undefined.
Option "TVChipset" "string"
This sets the TV chipset. Options are CH7005 or VT1621.
Default: off.
Option "TVSignal" "integer"
This sets the TV signalling. Options are 0 for NTSC or 1 for
PAL. Default: undefined.
Option "NoPciBurst" "boolean"
Turn off PCI burst mode, PCI Bursting is on by default.
Default: off.
Option "XvHsync" "integer"
Override the default Horizontal-sync value for the Xv extension.
This is used to center the Xv image on the screen. By default
the values are assigned based on the video card. Default: 0.
Option "XvVsync" "integer"
Override the default Vertical-sync value for the Xv extension.
This is used to center the Xv image on the screen. By default
the values are assigned based on the video card. Default: 0.
Option "XvBskew" "integer"
Override the default Bottom skew value for the Xv extension.
This is used to extend the Xv image on the screen at the bottom.
By default the values are assigned based on the video card.
Default: 0.
Option "XvRskew" "integer"
Override the default Right skew value for the Xv extension.
This is used to extend the Xv image on the screen at the right.
By default the values are assigned based on the video card.
Default: 0.
Option "Display" "string"
Override the display. Possible values are "CRT", "LCD" and
"Dual". Please note that this option is only experimentally.
Default: Use display active when X started.
Option "Display1400" "boolean"
Inform driver to expect 1400x1050 display instead of a
1280x1024. Default: off.
Option "GammaBrightness" "string"
Set display gamma value and brightness. "string" is "gamma,
brightness", where gamma is a floating point value greater than
0 and less or equal to 10. brightness is an integer value
greater or equal to 0 and less than 128. Default: gamma and
brightness control is turned off. Note: This is not supported
on all chipsets. Option "AccelMethod" "string" Choose
acceleration architecture, either "XAA" or "EXA". XAA is the
old (but stable) XFree86 based acceleration architecture. EXA
is a newer and simpler acceleration architecture designed to
better accelerate the X Render extension. Default: "XAA".
