DESCRIPTION

       trident	is  an Xorg driver for Trident video cards.  The driver is accelerated, and provides support for the following framebuffer depths:
       1, 4, 8, 15, 16, and 24. Multi-head configurations are supported.  The XvImage extension is supported on TGUI96xx and greater cards.

SUPPORTED HARDWARE

       The trident driver supports PCI,AGP and ISA video cards based on the following Trident chips:

       Blade	   Blade3D, CyberBlade series i1, i7 (DSTN), i1, i1 (DSTN), Ai1, Ai1 (DSTN), CyberBlade/e4, CyberBladeXP, CyberBladeAi1/XP,  Blad-
		   eXP

       Image	   3DImage975, 3DImage985, Cyber9520, Cyber9525, Cyber9397, Cyber9397DVD

       ProVidia    9682, 9685, Cyber9382, Cyber9385, Cyber9388

       TGUI	   9440AGi, 9660, 9680

       ISA/VLBus   8900C,  8900D,  9000,  9200CXr,  Cyber9320,	9400CXi, 9440AGi 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 graph-
	      ics 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".
