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, BladeXP

       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 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".
